Then, find some equipment to crush and grind the ore, and separate out the worthless material by the method of flotation, which will leave you a concentrate that typically composed by 2%-10% nickel and 5%-20% copper . Next, you need to smelt.

This stage is aided by the incorporation of regrinding equipment that helps lower the particle size and therefore liberate the copper minerals for performing a more selective flotation in the cleaning cells. Lastly, the scavenger stage, which.

Froth flotation - Wikipedia

The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also upgraded (purified) by flotation technology. Prior to 1907, nearly all the copper mined in the US came from underground vein deposits, averaging 2.5 percent copper.
