Most of the gold and silver produced comes from the processing of hard rock ores. There are a lot of different options for processing ores, and in the article below I'll take a look at all of the best known possibilities for getting the gold and silver out of your ore and producing a clean gold and silver .

In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.

high carbonate and arsenic content and an ore with high silver grade. Capital and operating cost estimates for different methods of pretreatment were prepared and these estimated costs and ore sulfide grades then used to compare the process economics.

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting .

the concentration of silver is greater than gold, the process that yields the most favourable economics for gold (and silver) recovery is Merrill Crowe cementation. In this process, the leachate is separated from the barren, leached ore, and gold and silver is precipitated from the pregnant liquor by reduction (cementation) on fine zinc powder.
