Science of the Comstock - Chemistry. Metals are taken from the rocks of an ore deposit using chemistry. In processing ore to recover the metal of interest, steps of the process can be divided into (a) the steps to prepare the metal for separation from the rest of the rock or other metals, and (b) steps to actually remove the metal from the rock and unusable or uninteresting parts of the ore.

The smelting process is about extracting the precious metal from its ore. The process yields about 90% of pure gold. However, this percentage of gold is not acceptable in the industry, as it comes with other minerals, such as copper, silver, iron, or aluminum. Smelting comes as the most crucial step of the entire gold mining.

Gangue rejection is the process of separating and disposing the poorest, low-quality, low-value material in an ore feed prior to further downstream processing. Simply put, the focus is on the waste to reject, rather than the mineral to recover. Economic benefits are gained when the gangue volume is replaced with useful material of a higher grade.
