Copper is usually mined in two ways: open-pit mining and underground mining. Open-pit mining is used for copper deposits closer to the surface. Enormous machines dig up the ground in stair-stepped layers (called …
Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as waste.

The research will focus on the company's Tamarack project, which comprises an underground nickel-copper mine in central Minnesota and a battery mineral processing facility in North Dakota.
Because most copper minerals have good floatability, flotation is one of the commonly used beneficiation methods for copper ore. After the ground copper ore powder is sent to the flotation machine, various elements rich in it will react with various chemical solvents added in the flotation machine. The flotation machine separates the copper ore ...
