Leaching of a polymetal gold ore and reducing cyanide

Many aspects of gold ores leaching by glycine C 2 H 5 NO 2 and glycine cyanide solutions are still not well understood.The baseponents have been shown to have a strong impact on gold leachingics. In this research, with the aim of reducing cyanide consumption, leaching of a polymetal Pb Cu Zn gold ore using a synergistic lixiviant mixture of cyanide

Gold Metallurgy Leaching in Cyanicides

14/7/2016· How Thiocyanate Affect Gold Leaching. The reason for the lower cyanide consumption obtained with intense aeration is probably connected with the reactions which take place when alkaline sulphideposes in cyanide solution. Alkaline sulphide is one of the initial products of the reaction between pyrrhotite and alkaline cyanide solution.

Heap leaching of gold ore Afuruika

Heap leaching process: With the site, hundreds of tons or even thousands of tons of low grade gold ore were piled into 1.2 12m high ore piles.The solution containing sodium cyanide is sprayed evenlyprehensively on the pile with a sprinkler, and a layer of mesh system is installed on the top of the pile to ensure uniform spraying.The heap leaching site is slightly

A study of thiosulfate leaching of gold from carbonaceous

The objective of this study was to investigate leaching of gold from carbonaceous ore using ammoniacal thiosulfate solutions, and to determine the consumption of thiosulfate during leaching. The quantitative determination of thiosulfate in the leached solution in the presence of sulfite and sulfate ions wasplished by means of flow injection analysis with

The leaching and adsorption behaviour of gold ores

from the dissociation ofplex is used to leach gold from the ore. The stepwise dissociation of cyanide from copperplexes can also be used to leach gold from a variety of oxide and sulphide ores. The copper cyanide's fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.

High Sulfur Gold Ore Heap Leaching Hydrometallurgy

The lime consumption will be huge and your solution off your heap can go acidic, creating all kinds of havoc with iron, copper, nickel, zinc, or whatever other metals you have in your ore. Cyanide consumption will go way up and carbon can get way overloaded with base metalplexes, which will cut down your gold loading capability.

Application of SART to Heap Leaching of Gold Copper SGS

the Refugio mine relative to other gold and copper mines in the region. The Maricunga mine produces 45,000 52,000 t/day of gold bearing ores from . the Verde Open pit, with ore gold grades ranging from 0.6 1.0 g/t and copper levels of 0.05 0.1 . The operations flowsheet is schematically given in Figure 2. Blasted ore is trucked from the

THIOSULPHATE LEACHING SGS

and greater efficiency with gold deposits associated with preg robbing ores. The thiosulphate leaching process, followed by resin in pulp gold extraction, has been developed by SGS to the point where it is a technically and economically viable alternative to cyanidation for some gold bearing ore bodies. Whether the leaching is performed in
