Ore Dressing Methods
In general, cyanide treatment comprises four steps—preparation of the ore (crushing, screening, grinding, and classification), leaching or dissolving the gold, separation of the gold-bearing ("pregnant") solution from the leached pulp (thickening, filtration, and clarification of the solution), and precipitation.

Acid Leaching
PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.
