Mineral processing metallurgy Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations

Primary crushed ore from the open pit is fed into world's biggest grinding mills to produce a fine powder. Each of Sino Iron's six milling lines consists of a primary autogenous (AG) mill and a secondary ball mill. Following three stages of magnetic separation and passing through the ball mill, the final high grade concentrate is produced.

Copper extraction Wikipedia

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 leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.. Carbonate concentrates are a relatively minor product

Copper Ore Types: Sulfides vs. Oxides An Investor's

The above information provides a good overview of the types of copper ore and how copper processing occurs, but as all savvy investors know, more information is better.

Beneficiation of Iron Ore Mineral Processing & Metallurgy

Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500
