Recovery of gold from chloride solution with ion exchange

01/12/1990· The extraction of gold from chloride solutions by ion exchange is examined. It is shown that at initial gold concentrations between 1-5 ppm, 20 g/l Cl-and pH 5, the kinetics of loading on weak base resins are slightly slower than those observed with activated charcoal. Equilibrium loading of auric chloride varies considerably as a function of pH from one resin to another.

Gold Extraction & Recovery Processes

Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm. This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation. For many years, a combination of amalgamation, cyanidation and

Leaching of an oxide gold ore with chloride/hypochlorite

An oxide gold ore was subjected to chloride/hypochlorite leaching at room temperature. The effects of three factors, including Ca(OCl) 2 vs. NaOCl, OCl − concentration, and HCl concentration on gold leaching performance were investigated. Due to formation of CaOCl + complex in solution and hence less reactivity, calcium hypochlorite produces a sluggish gold leaching kinetics, taking twice

Processing, smelting and refining gold World Gold

In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the gold migrates to a negatively charged electrode (cathode), where it is restored to a highly pure metallic state, leaving the impurities as a separate solution or residue.

Gold Ore Roasting Techniques

Recover Gold by Roasting Pyrite Ore. The roasting of straight pyritic ores involves the conversion of the iron sulphides to the oxide under oxidizing conditions with the evolution of sulphur dioxide and, to some extent by catalytic action, sulphur trioxide gas also. In this stone change the iron mineral is rendered more or less porous, thereby permitting the dissolution of the contained

Extraction of Gold

In the gold-chloride method the electrolyte is a solution of auric chloride containing free hydrochloric acid, the crude metal forming the anode, and pure sheet gold the cathode. The gold dissolved at the anode is deposited in a pure condition at the cathode. Other metals are converted into chlorides at the anode, and either remain dissolved or pass into the anodic slime. Silver is converted

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

Claude Theodore James Vautin, a man of much practical experience of gold mining and extraction in Queensland, Australia, By this means all the gold chlorides contained in the wet ore may be washed out, a continual stream being passed through it while filtration is going on. The solution running from the filter is continually tested, and when found free from gold, the stream of water is
