It Started With An Idea New Gold Recovery

Traditional methods of mineral processing reduce ore into fine particles called “tailings” or “flour” which are left in piles or simply thrown out. There are millions of such piles around the planet. Instead of only going after gold nuggets and flakes, we examined the subject of mineral extraction at a microscopic level.

New gold extraction method both cheaper and faster

18/04/2017· The main problem of the traditional technology is the long process about 100-120 hours. In addition, copper often dilutes the gold extract and due to that the degree of the precious metal remains relatively low, despite the high cost of production, researchers said. The cost of about 28 grammes of gold obtained by using direct cyanidation from similar ores could reach USD 800, which

Processing, smelting and refining gold World Gold Council

15/05/2021· More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding

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
