why is copper ore crushed

Copper extraction - Wikipedia

The modern froth flotation process was independently invented the early 1900s in Australia by C.V Potter and around the same time by G. D. Delprat. All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting. Some vat leach or pressure leachprocesses exist to solubilise chalcocite concentrates and produce copper cathode from t

Crushed Copper Ore - Eco - English Wiki

Mar 12, 2021 · Crushed Copper Ore is created by crushing Copper Ore in one of three different crafting stations. The crafting stations come with different ratios, labor cost and time cost. The two lower crafting stations also have a by product of Crushed Granite. Crushed Copper Ore needs to be further refined to Copper Concentrate before it can be smelted into a Copper Bar.

After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and “worthless” rock, called gangue (pronounced “gang”). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue. Chemical reagents called ...

Copper extraction - Wikipedia

The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals. The ore is then wetted, suspended in a slurry, and mixed with xanthates or other reagents, which render the sulfide particles hydrophobic .
