FROTH FLOTATION "So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined." The froth flotation process was patented by E. L lman H. F. K. Pickard and John Ballot in 1906 19 years after the first cyanide process patents of MacArthur and the Forests.

The Escondida copper-gold-silver mine is located in the arid northern Atacama Desert of Chile about 160km southeast the port of Antofagasta at an elevation of 3 050m above sea level. The mine is a joint venture between BHP-Billiton (57.5 ) Rio Tinto (30 ) a Japanese consortium (10 ) and the

The material that sinks in the first flotation cell goes on to two more flotation cells to recover as much copper as possible. What doesn t float is called tailings because it goes out the "tail end" of the flotation circuit. About 80 percent of the water used in the milling process is reclaimed and re-used.

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

The four major steps in the production of marketable copper are mining concentrating smelting and refining. In a few instances however leaching takes the place of concentrating smelting and refining. At present although considerable leaching and direct-smelting ores are produced the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
