Copper–gold ore processing with ion exchange and SART ...

2014-10-1  Ore processing is by conventional cyanide heap leaching, which produces a pregnant leach solution (PLS) containing 1–2 ppm of gold, together with 1000 ppm or more of copper. The PLS is treated by column ion exchange, using Dow’s gold-selective MINIX resin. Loaded resin is stripped with an acidic thiourea solution, from which gold and silver ...

Recovery of gold from chloride solution with ion exchange ...

1990-12-1  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 processing with resin - bostonenglish

Processing of residual gold (III) solutions via ion exchange. adsorption of gold (III) into the resin must be considered as a liquid-solid phase reaction which includes the diffusion of gold (III) species from the aqueous solution to the resin surface, the diffusion of ions within the resin and the moving boundary process.

Extraction of Gold

When the gold has solidified, the molten silver chloride collected on the surface is run off, carrying with it a small proportion of gold. When silver is the chief impurity in the gold, as in that found in Australia, the process is specially applicable. The gold has a degree of purity of 99.1 to 99.7 per cent.
