Iron and Manganese in Private Water Systems

 · Manganese often results in a dense black stain or solid. For these reasons, it is recommended that drinking water have no more than 0.3 mg/L (or 0.3 parts per million) of iron and less than 0.05 mg/L of manganese. The U.S. Environmental Protection Agency has also set a Health Advisory for manganese of 0.3 mg/L.

During mining, metal-bearing rock called ore is extracted from underground or surface mines. Metal concentrations in ore vary greatly, from less than 1 percent by weight for most gold deposits to over 60 percent for some iron ore deposits; most metallic mineral deposits have ore grades in the range of 1–5 percent by weight.

Mining in Minnesota | Minnesota DNR

Silica sand is a very fine sand composed of quartz (a white to colorless mineral) and is mined in the southeastern part of Minnesota. It is used to make glass, as a source of silicon, and is used in oil drilling to improve the flow of oil to oil wells. Granite and limestone are used in the construction of homes, buildings, roads and tombstones.

Extracting Gold | HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.
