cyanide device processing sulfide ores low consumption

Ore Flotation Gold Ore Cyanide Process Low Consumption

Ore Flotation Gold Ore Cyanide Process Low Consumption. The consumption of cyanide during processing operations is a major economic cost in the extraction of gold from its ores, while the discharge of cyanide wastes may result in significant environmental pollution.

Cyanide Management by SART - SGS

Telfer Gold Mine treats both gold/copper oxide and sulfide ores in a remote lo ion in the Great Sandy Desert, Western Australia. Currently, the oxide gold ore is treated in a conventional CIL circuit by blending the low and high grade copper ores to minimize cyanide consumption and allow smooth operation. The sulfide ore is treated

PDF Cyanidation of a pyrrhotite-bearing gold ore

The ore with a low sulphide content required a pre-leaching of only 1 h with a small quantity of Pb NO3 2 50 g/t and leaching can be performed at 360 ppm NaCN to allow a recovery of 96.4% Au and ...

Guides For High-sulfide Gold Processing

High sulfide gold ore refers to a certain gold ore with 20% -30% of gold wrapped by sulfide mainly pyrite . Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold, when using direct leaching process, the consumption of gold leaching agent and cost of gold leaching production will increase, and gold processing efficiency is not good.

Estimating process design gold extraction, leach residence ...

Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The appli ion of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores. Such scale-up factors may not be appropriate for ores that deplete cyanide and ...

Cyanide Device Nickel Ore Mining Process Low Consumption

Cyanide Device Nickel Ore Mining Process Low Consumption. We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.

Treatment of Gold–Telluride Ores - ScienceDirect

Dissolved oxygen DO levels as low as 1–2 ppm were shown to have a beneficial effect in reducing the cyanide consumption while maintaining gold recovery. Measured thiocyanate SCN levels in solution dropped from >1000 mg/L to <200 mg/L, indi ing that the cyanide side reaction with sulfur compounds had been significantly reduced.

Rebellious Ores: Sulfides, Selenides and Tellurides

Many sulfide minerals also contain things like copper or antimony that can react with the cyanide, preventing the cyanide from leaching out the gold and silver. For information on methods to deal with and extract gold, silver and base metals from these refractory ores, I recommend two pages on this website.
