Larger process plants have a lower operating cost per unit weight of material than a smaller plant using similar processes, but they also have a larger initial capital cost. For reference, a 1 Mt/a mill will have a capital cost within 25,000 /t/h and 50,000 /t/h.

Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes:
