Flotation ore dressing Britannica. Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
Treatment of 1 t of copper ore consumes in the region of 1500 2000 kWh of electrical energy which at a cost of say 3.5p per kWh is around 60 t, well above the contained value of all current copper ores.（p.8） The cost of transportation of mined ore to remote smelters could in many cases be greater than the contained value of the ore. （p.8）.

May 22, 2018 You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.
Porphyry copper ore was crushed to 10 mesh and 700 g of the crushed ore was ground in the laboratory ball mill together with 500 mls of water, 3.8 g of lime, 5 mg of A 54 (a liquid hydrocarbon fraction supplied by Shell Oil Company), and 5 mg of one of the above collector materials, the 5 mg quantity corresponding to 0.014 lb of collector per.
Sol Gold and silver ores are concentrated by leaching. In this method, we treat the ore with a suitable reagent in which ore is soluble but impurities do not. Thus, impurities are removed by filtration. Among galena, copper pyrites, cinnabar and Argentine, Argentite being silver ore is concentrated by chemical leaching method.
