    • Mining for Tin in The Dutch Indies Tin is one of the most valuable metals and plays a major role in the economy. Rarely found in its pure form, it is generally mined as an oxide, as so-called tin ore. Pure tin is gained by melting the ore at high temperatures. An international agreement on the mining of tin put an end to its flooding onto the world market and the associated fall in [trade] prices. Thus, the artificially high world market prices for tin allow some tin mines to survive, while others even make enormous profits. Undated Captions for the photos: Negt. 27, 17, 19 Negt. 25 Negt. 15, 16, 18 Negt. 10, 11, 13, 19, 18a (a-negatives are notched) Negt. 4, 5, 6, 7, 8, 9 , 14, 15a, 16a, 17a, 20, 22, 23,24 Negt. 21 A tin excavator in operation. The excavator shown here is operating at the Strait of Banka; last year its owner made a profit of over 4 million guilders. A shovel filled with tin ore. The main part of our tin is gained from black or brown tin oxide, although tin ore can be found in a wide range of colours. The tin ore shown here contains approximately 70% pure tin. Tin ore is washed out of the excavated mud. Workers in the tin mines are practically all Chinese coolies. Malays and Javanese have proven to be less useful. The clearing of a new tin mine. A new tin mine is being cleared on Sinkep Island using hydraulic-jet ventilation. Here, tin ore is found, mixed with rocks and sand. The water washes everything through channels; while the heavy tin ore settles on the bottom, sand and stones are washed out. View across a tin mine under development. The required water is stored in enormous dams, at a distance from the actual site. In arid regions the mining is done in stages and the water used for separating the ore is always recycled in a series of enormous dams that progress in accordance with the mine. The material for building the dams comes at no extra cost. It is logged by the natives in the_ nearby jungle
