History of Mining Equipment & Practices

The introduction of a cyanide process, developed between 1887 and 1897, proved more efficient with gold ore. It exploited the fact that gold dissolves in a solution of sodium-cyanide. Millers washed pulverized ore with the solution, poured off the result, and mixed it with zinc shavings, which left the gold behind.

Copper Mining and Processing: Everything you Need to Know

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.
