By 2000 bc the process of purifying goldsilver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain.

Heap Leaching Flow Chart Incorporating Agglomeration into the Heap Leaching Process. The agglomeration of the fines in the heap leaching process allows for enhanced, even percolation of a heap. If left untreated, smaller fines can accumulate in the spaces between larger particles, inhibiting flow of the leaching solution (see figure 2).

Carbonin leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain pregrobbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.

Figure 4 CIL/ CIP Process Flow Schematic. Both CIP and CIL are continuous processes, where activated carbon is added to the ore/ water pulp. The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen. Next, the gold adsorbs to the activated carbon.
