Flotation, which used "frothing" machines to mix air bubbles with oil and finely ground ore, emerged by the early twentieth century to do the same thing. Miners then shipped the resulting concentrates to smelters for further processing. Miners used chemicals, heat, and electricity to process more complex metal and mineral compounds.
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 main ores of copper are sulfides and .
Introduction to Mineral Processing. ... The figure below is a simplified schematic of a typical copper solvent extraction process. Oxide copper ore, lowgrade copper sulfide overburden, and other coppercontaining materials are stacked into a heap. Leach solution (pH approximately 2) is sprinkled or flooded on top of the heap and percolates ...
Copper Mining Info The above flowsheet shows a basic copper mine process, from mine to metal. There are two distinct types of copper ore, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and ...
