The northeast region of Minnesota, often referred to as the "Iron Range," has a history of iron ore mining dating back to the 1880s. While the focus of mining to date has been iron deposits (known as "ferrous mining"), the ores also contain a variety of precious metals including copper and nickel.
Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur.
The gravity method was applied not only because of the known good response to massive sulphides but also as a tool to help distinguish between graphite and sulphides. Anoxic sedimentary horizons that contain graphite or sulphide ore are highly conductive and are difficult to distinguish from massive sulphide deposits (Morgan, 2012).

Lead oxide ore, mainly in the form of cerussite and anglesite, is originated from primary lead sulfide ore which gradually changed its property under efflorescence and carbonate salt environment. In a lead deposit, lead oxide and lead sulfide usually is detected at the upper layer and lower layer separately.

Why Is Sulfide Mining Dangerous? If sulfide ore or sulfide tailings are exposed to water and air during mining, a chemical reaction creates sulfuric acid – basically battery acid. There has never been a sulfide mine that has not polluted nearby water resources. Pollution from sulfide mining is very expensive to fix, and a burden for taxpayers.

Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
Sulfide mining, unfortunately, poses several significant environmental risks. The most significant one is the threat to water quality. When sulfide ores are exposed to air and water, the result is sulfuric acid, which causes the leaching of potentially toxic heavy metals and the release of sulfates that contribute to the methylation of mercury.
