Applications: Copper Compounds - Copper Sulphate
By heating copper sulphide ores to produce copper oxide which is then treated with sulphuric acid to form copper sulphate. By slow leaching in air of piles of low grade ore. Bacterial action is sometimes employed to hasten the process. A solution of copper sulphate drains away from such heaps.
Patio process - Wikipedia
The patio process is a process for extracting silver from ore.The process was invented by Bartolomé de Medina in Pachuca, Mexico, in 1554. The patio process was the first process to use mercury amalgamation to recover silver from ore. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas.

- Copper ore-bearing rocks (normal rocks with bits of bronzey stuff on them) allows your copper miner to mine, well, copper, off them. The copper can then be transformed into either bronze or cash. - Iron ore-bearing rocks (normal rocks with bits of silvery stuff) can be mined by an iron miner and made into steel or iron.
Copper Mining and Extraction Sulfide Ores
Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining.
Copper Production: How Is Copper Made? - The Balance
Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.
