By the end of the smelt the Gold extraction Wikipedia 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 in direct recovery of Gold processing Mining and concentrating Britannica Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for Production of Gold Biomedical Engineering the heap leaching technology. The problem is to find the break-even price of gold for this mining operation. The process is currently unprofitable with a gold price around $300 per ounce.
