Copper processing - copper processing - roasting, smelting, and converting: once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. in older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or ...

Class-10 » science. metals and non-metals. how is copper obtained from its sulphide ore? give equations of the reactions please give me a 2 mark level answer share with your friends. share 8. copper is a metal that is present low in the reactivity series. it mainly occurs in nature in the form of sulphide ore which can be converted into the ...

Extraction of copper directly from sulphide ore is less favourable than from its oxide through reduction. explain. asked dec 18, 2017 in chemistry by sforrest072 ( 127k points)

Extraction of metals of least reactivity. mercury and copper, which belong to the least reactivity series, are often found in the form of their sulphide ores. cinnabar (hgs) is the ore of mercury. copper glance (cu 2 s) is the ore of copper. extraction of mercury metal: cinnabar (hgs) is first heated in air. this turns hgs [mercury sulphide or ...

Through a process called hydrometallurgy, copper from its low grade ore is leached (drained) out using acid or bacteria and then cu 2+ ions in the solution are reduced to copper by treating with hydrogen or iron. as hydrogen is used for reduction, the process is named hydrometallurgy.
