En ellos se muestra que los diamantes, oro, cobre, uranio, fosfatos, bauxita y otros minerales de interés han sido explotados durante muchos siglos por los nativos utilizando métodos primitivos y posteriormente por los colonizadores europeos que introdujeron las máquinas. PALABRAS CLAVE: Minería, filatelia, historia, Africa ABSTRACT The history of mining and metallurgy in Africa can be readily traced by studying the stamps issued over the years by the different African countries. It is shown that diamonds, gold, copper, uranium, phosphate rock, bauxite, and other mineral wealth have been exploited for centuries by the original inhabitants using primitive methods as and then by the European colonizers who introduced machines. KEYWORDS: Mining, stamps, history, Africa. INTRODUCTION Before being colonized by the Europeans, the inhabitants of Africa have pursued mining of ores and the extraction of metals in a primitive way since ancient times. Gold was mined by the ancient Egyptians and made into magnificent artefacts (Fig. 1). They quarried granite (Fig. 2) and other semi-precious stones and made huge statues (Fig. 3) and vessels (Fig. 4). Botswana the former British colony Bechuanaland in southern Africa issued in 1980 stamps entitled “Early Mining”, covering rock breaking (Fig. 5), ore grinding (Fig. 6), ore transport (on oxen) (Fig. 7), ore smelting Fig. (8), and the tools and products of ancient miners (Fig. 9). The stamp showing “ore grinding” is of special interest since it records a technology commonly used by the Africans before the introduction of machines. A large granite boulder was tilted back and forth by two men sitting on a wooden beam fixed on top of the boulder. This method was apparently quite common that it was documented by the South African artist Thomas Figure 2 Figure 1 Baines (1820-1875) who painted this scene that is preserved at the Port Elizabeth Library in South Africa. Modern mining methods were later introduced by Europeans (Figs. 10-13).

The discovery of diamonds at Kimberley in South Africa and the discovery of large gold deposits in the Witwatersrand region of the Transvaal in 1886 caused an influx of European, mainly British immigration and investment. In addition many blacks from neighbouring countries also moved into the area to work in the mines. In 1880, Cecil Rhodes (1853 –1902) (Fig. 14) launched the De Beers Mining Company after the amalgamation of a number of individual claims. The 12 De Re Metallica 9 diciembre 2007 2ª época Boer reactions to this influx and British political plots led to the Anglo-Boer Wars of 1880-81 and 1899-1902 which resulted in the incorporation of the Boer Republics of the Transvaal and Orange Free State into the British Empire. In 1910, the Union of South Africa was formed as a self-governing dominion of the British Empire. Rhodes made a fortune by monopoly of diamond production. He was prime minister of Cape Colony from 1890 to 1896. He left a part of his fortune to public service including Rhodes Scholarships. DIAMONDS The major suppliers of diamonds in Africa issued stamps emphasizing this fact: • Ivory Coast issued in 1972 a stamp showing a diamond and a diamond mine (Fig. 15). • The Kingdom of Lesotho once called Basutoland, issued a stamp entitled “Diamond Mining” which illustrates miners and a mining machine (Fig. 16) and another entitled “Brown Diamond” (Fig. 17). On the occasion of the International Conference on Kimberlites in 1973 Losotho issued a stamp showing a worker prospecting for diamond (Fig. 18). Figura 15 • Sierra Leone issued a stamp in 1961 on the occasion of her independence, showing a man panning for diamonds (Fig. 19). • Botswana (Fig. 20), the Republic of Central Africa (Fig. 21), Ghana (Fig. 22), and South-West Africa (now Namibia) (Fig. 23). • Zaire shows a naturally-occurring diamond and a gem cut from it (Fig. 24). • The Republic of South Africa shows a 530.2 karat diamond known as Cullinan 1 (Fig. 25) on the occasion of the World Diamond Congress; a karat is 200 mg.

Figura 26 Figura 27 Figura 28 Figura 29 Figura 32 Figura 30 Figura 31 Figura 33 Figura 34 Figura 36 Figura 37 Figura 40 Figura 38 14 De Re Metallica 9 Figura 35 diciembre 2007 2ª época Figura 39 GOLD Present day Ghana was formerly known as Gold Coast because of the abundance of gold in the region and its extensive trade with the Europeans (Fig. 41). She is still a large producer of gold; a stamp entitled “Gold” showing a miner with a pneumatic drill and ingots of gold was issued on the occasion of 20th anniversary of the United Nations Conference on Trade and Development (Fig. 42). Figura 46 Figura 45 Figura 42 Figura 47 Figura 41 Gold was discovered in Swaziland in 1879 (Fig. 43). Stamp mills were introduced there for crushing of ore and amalgamation of gold (Fig. 44). Later cyanidation process was introduced (Fig. 45). Witwatersrand in South Africa, also known as the Rand, is the most productive gold-mining district in the world. Surface gold was discovered in the region in 1884, and active mining operations began in 1886, the same year in which Johannesburg was founded as a gold-mining settlement. The main gold reef was discovered in the region in 1889, at a depth of 177 m. The tailings of mining operations form heaps in the background, is a typical sight in the city (Fig. 46). Gold also occurs in Liberia (Fig. 47) and Zimbabwi (Fig. 48). Modern Algeria is also active in gold mining. She showed her gold mine at Tirek-Amesmessa in the south of the country on a map and a sample of the ore. Mozambique issued a stamp entitled “Ouro” showing a miner washing gold-containing sand (Fig. 49). Figura 44 Figura 43 Figura 48 Figura 49 COPPER Zambia, a large copper producer, issued a stamp entitled copper mining showing a miner at work and the alchemists symbol for copper (Fig. 50). Another stamp shows a train transporting copper ore (Fig. 51) and another entitled “Poling a Furnace” showing a worker manipulating a greenwood tree in the anode furnace to remove residual oxygen before casting the molten copper in form of anodes for electrolytic refining (Fig. 52). Uganda, another copper producer, issued a stamp in 1962 celebrating its independence entitled “Copper Mining”. The stamp shows miners drilling the rock to the left and a copper converter pouring its molten charge to the right (Fig. 53). A copper converter also appears on a 1984 Bophuthatswana stamp (Fig. 54) (one of the nine so-called independent Black Homelands in South Africa with its capital Mafeking, during the Apartheid governmenet, is now part of the Republic of South Africa after the fall of the White Rule). Botswana issued a stamp on smelting copper-nickel sulfide concentrates (Fig. 55). A copper mine is shown on a 1959 stamp from Rhodesia & Nyasaland, former British colonies (Fig. 56). De Re Metallica 9 diciembre 2007 2ª época 15 Figura 50 Figura 51 Figura 53 Figura 52 Figura 54 Figura 55 Figura 56 URANIUM South Africa issued a stamp in 1977 entitled “Uranium Development” to mark 25 years nuclear power plants; the stamp shows atom symbol (Fig. 57). The Gabon Republic issued a stamp in 1965 showing the operation at Mounana (Fig. 58). It was there at Oklo mine in the Mounana District that the phenomenon of natural fission was discovered and also the traces of naturally-occurring plutonium. at the entrance of the Red Sea. Djibouti, the territory’s capital was a free port and the terminus of the FrenchEthiopian Railway. The Territory was ethnically and politically divided between the majority Issas (Somali) tribe and the minority Afar (Ethiopian) tribe also known as Danakil. The Issas campaigned for independence while the Afar wanted to maintain ties with France. Clashes between the two factions resulted in bloodshed and France changed the name of the Territory to eliminate reference to the Somali ethnic group. Conflict, however, continued until the territory gained its independence in 1977 after French occupation for over a century, to become the Republic of Djibouti. Figura 58 Figura 59 OTHER METALS Figura 57 A stamp entitled “Ra”, i.e., radium, a decay product of uranium, was issued in 1974 by the French Territory Afars and Issas (Fig. 59). Known until 1967 as French Somaliland and situated in East Africa at Bab el-Mandab 16 De Re Metallica 9 diciembre 2007 2ª época Zimbabwe and South Africa issued stamps showing chromium smelting. Bophuthatswana, a former self-ruling African republic in South Africa, famous for its gambling casinos in Sun City, issued a series of stamps in 1979 entitled “Platinum” showing molten metal pouring from a ladle and application of the metal. South Africa issued in 1984 a stamp entitled “V” for vanadium showing the metal pouring from a furnace and a sample of the metal. Botswana in 1970 recognized its nickel development program with two stamps on mining at Selebi-Pikwe, one portrayed two nickel miners underground and the other a mine head frame and nickel and copper ingots. In 1984, a stamp illustrating copper-nickel mineral was also issued by Botswana. Gold Coast, the present Republic of Ghana issued a stamp in 1948 for its manganese mine (Fig. 60). The Republic of South Africa is also a manganese producer. Tin is produced in Nigeria (Fig. 61) The Republic of South Africa issued in 1984 a series of stamps devoted to her mineral and metal industries of which one is for titanium. Namibia, the former German colony of South West Africa issued a series of stamps in 1991 devoted to her mineral wealth: the Tsumeb copper-lead-zinc mine the Rosh Pinah zinc mine, the Vis tin mine, and the Rössing uranium mine. Mauritania has large iron deposits in the Zouerate district. A stamp showing mining activity was issued (Fig. 62). Sierra Leone shows iron ore production at Marampa on a stamp issued in 1956. An Algerian stamp shows the iron ore deposits of its open pit at Djebel Ouenza, a location map, and a sample of its ore. mines; the stamp is entitled “Natural Resources. Mining”, while Zimbabwe issued a stamp showing modern coal mining equipment. Samples of bauxite are shown on stamp from Ghana, the former British colony Gold Coast. The equatorial west African countries: Guinea (a former French colony) and its neighbor Sierra Leone (a former British colony), possess large deposits of bauxite. The former issued a stamp showing charging bauxite in wagons (Fig. 63). Clays are abundant industrial minerals. They are hydrated alumium silicates. Together with limestone they are used in the manufacture of cement. The raw materials are heated at high temperature in slowly rotating and slightly inclined furnaces known as kilns. Rare crystals of gypsum known as “Flowers of the Desert” are shown on a South West African stamp. Figura 63 PHOSPHATE ROCK Figura 60 Figura 61 Figura 62 North and Central African countries are large producers of phosphate rock. Morocco in 1947, issued a stamp marking the 25th anniversary of the foundation of the industry; the stamp shows the location of the two mines at Khouribga and Louis Gentil, the port of Safi, and Casablanca where the administration is located (Fig. 64). The importance of phosphate for agriculture is indicated by fruits and wheat at the lower right corner of the stamp. In 1991, the 70th anniversary of the industry is marked on another stamp. The phosphate industry in Morocco is a nationalized industry controlled by the Office Cherifien du Phosphate. From Central Africa, a Senegalese stamp (1964) depicts the phosphate mine at Pallo. Togo issued a series of stamps on the exploitation of the local phosphate deposits in 1964 on the occasion of the 4th anniversary of her independence from France in 1960. OTHER ORES Coal has a special place in the mining industry. It is the largest industrial mineral mined in terms of tonnage and the most dangerous because of the presence of explosive and combustible hydrocarbon gases in the mines. Many countries have recognized the importance of coal to their economy and stamps were issued honoring the industry. The Kingdom of Swaziland in southern Africa issued a stamp in 1973 showing the Mpaka coal Figura 64 De Re Metallica 9 diciembre 2007 2ª época 17 SALT EPILOGUE Salt is the most ancient industrial mineral, it was already recovered from sea water and from underground mines by the ancient peoples. Many ancient trade routes have been due to salt localities or salt springs and battles have been fought for their possession. Salt has at times served for currency, and during many centuries in many countries has served as a salary. The word salary comes from Latin for salt. A scene of modern salt production are shown on stamps from the former South West Africa (the present Namibia)1. Postage stamps are important means of communication and many countries have recorded important events, honoured worthy individuals, and described interesting facts through this medium. Many historical facts, sometimes obscure, can be found on stamps; some of these may not be easily located in a history or a science book. Stamps have artistic value, they are created by artists. REFERENCE CONFERENCES It is natural that a mining or metallurgy theme is designed for a conference dealing with any of these topics. For example, when the Seventh Commonwealth Mining and Metallurgy Congress was held in1961 in Rhodesia and Nyasaland2 a stamp was issued on this occasion showing a miner at work underground (Fig. 65), and another showing mine shafts and the processing plant. Morocco issued two stamps in 1987 showing different minerals on the occasion of holding the Congress on Mineral Industries in Marrakesh. Figura 65 18 De Re Metallica 9 diciembre 2007 2ª época F.

E-mail: conseiller@zone.ul.ca NOTES 1 Namibia, formerly South-West Africa, was a German colony since 1884. During World War I, it was occupied by South Africa forces. In terms of the Versailles Treaty it became under South Africa administration. All attempts to annex it to South Africa during the Apartheid regime was rejected by the United Nations. Finally she obtained independence in 1983. 2 Rhodesia, formerly the self-governing colony of Southern Rhodesia, the land that was known to its ruling white population as Rhodesia and to Africans as Zimbabwe occupies the fertile plateaus and mountain ranges between the Zambezi and Limpopo rivers in southeastern Africa. In 1953 it joined with Northern Rhodesia (now Zambia) and Nyasaland (now Malawi) in the so-called Federation of Rhodesia and Nyasaland, reverting to separate status in 1963 when the Federation was dissolved and its two parteners prepared to claim their independence.
