This method especially suitable for processing of low grade precious ore. Cyanide process can be divided into mixing cyanide and the percolation cyanide. Mixing cyanide is to re-election the gold mineral after amalgamation, tailings and flotation, or use for all slime cyanide; but percolation cyanide is used for processing flotation tailings ...
The grade of gold in the orebody can be critical in establishing the process options. Maximum gold recovery can normally be justified for high-grade deposits, even though this usually means relatively high capital and operating costs. Conversely, low-grade deposits .

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 ...
Jul 20, 2020· For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining
The cyanide solution percolates through the ore and dissolves the gold, which is then removed from the lixiviant by adsorption onto carbon or resins. Grain size, oxygen and alkalinity levels are carefully controlled to ensure maximum gold recovery. Heap Leaching. Heap leaching facilitates the profitable extraction of gold from very low grade ore.
The mining industry supplies the manufacturing industry and the chemical industry with its raw materials, for example iron is distributed to steel manufacturing industries.
