Zinc ores typically may contain from 3 to 11 percent zinc, along with cadmium, copper, lead, silver, and iron. Beneficiation, or the concentration of the zinc in the recovered ore, is accomplished at or near the mine by crushing, grinding, and flotation process. Once concentrated, the zinc ore is

Montana Mines Mining Artifacts

The early claims were predominantly placer mines, but by 1870 there were a significant number of underground quartz mines. These mines required a large investment in stamp mills, reduction works, and smelters to treat the ore. Different mining districts produced different metals depending on the geology of the area.

Copper is extracted in large amounts from the Earth's crust by mining of sulphide ores and also oxide ores. Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicate, carbonate or sulphate ores.

Redox reaction from dissolving zinc in copper sulfate

So what we have here is a solution of a copper sulfate. And copper sulfate is an ionic compound. The copper loses two electrons to the sulfate. So the copper has a positive 2 charge, and the sulfate has a negative 2 charge. This is a cation. This is an anion. So you could imagine it's very easy to dissolve it in a polar solvent like water.
