The leaching of copper ores is conducted somewhat differently depending on the minerals present in the ore. Oxide ores containing chrysocolla, malachite, azurite, cuprite, etc., are readily amenable to acid leaching. An acid solution is often mixed with the ore during agglomeration to initial leaching while the material is being stacked.

Hong Yong Sohn, ... Bart Blanpain, in Treatise on Process Metallurgy: Industrial Processes, 2014. 2.1.1.3.1 Dead Roasting and Reduction. In this path, copper minerals are oxidized in the solid state to produce Cu 2 O and Fe 2 O 3.Cu 2 O is then reduced to molten Cu, typically in a blast furnace charged with coke. Flux is also added to form a molten slag in which the iron oxides are removed.

Firstly, the miners need to determine what type of ore it is because if it is oxide based then electrolysis is the best option, if it is sulfide based then smelting is the better option. Secondly, if the ore (Chalcopyrite) is oxide based then electrolysis is the better option, the ore is mined from the ground and brought to leaching areas.

Most iron is used to manufacture steel. Most of Canada's iron ore comes from the Labrador Trough region, along the border between Quebec and Newfoundland. Iron is made by putting iron-ore into a blast furnace with a resulting pig-iron. In solar panels, iron is used to make a cheaper and more effective solar cell.
