The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.

Copper (Cu) ore is a naturally occurring mineral deposit that contains copper in varying concentrations. It is an important industrial metal that has been used by human civilizations for thousands of years due to its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion. Copper is widely used in various …

Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest …

Iron oxide copper gold ore is found on the edges of granite or as long bands of dark rock flecked with gold. Sulfide gold ores will be filled with shiny flecks, but not all of them will be gold. Gold and fool's gold can form alongside each other, making this kind of ore deceptively chock full of shiny material.

While stamp mills throughout the west were similar in how they crushed the ore, the second stage – separation of the metals from the crushed ore – varied widely based on an array of factors. Basic ores, sometimes called "free milling ore", could be separated by relatively simple processes like amalgamation.
