US4723998A - Recovery of gold from carbonaceous ores

A gold recovery process is disclosed in which the gold content of ores, including carbonaceous ores or mixtures of carbonaceous and oxide ores, is extracted by a simultaneous chlorine leach and ion exchange resin adsorption procedure. The process eliminates or reduces the degree of oxygenation and cyanidation required to conduct a standard gold extraction process.

2014-6-22  Interested in using mercury to recover gold and silver and get all the gold out of your black sands? There is often some very small sized gold in our concentrates, and it can be a lot of work to get all the gold out. Yet we make a lot of effort to capture the gold and we don't want to throw any fine gold away as it can be so valuable.

Gold Fingers - How to Recover Gold from Electronic Scrap

The complete mechanism of the copper chloride etching process is actually quite complicated and to be honest, can be quite boring. But there are three key ingredients which drives the stripping process of gold plating and are important to remember and sustain: A. Free HCl B. CuCl2 presence C. Dissolved Oxygen. If the above paragraph isn’t quite clear to you at the moment, don’t worry and ...

In any recovery operation, once you get down to hard pan, it just won't go any further, that is when you are leaching soluble salts through the soil. The heap leach system moves gold and silver solutes down to a plastic membrane where they collect as a slurry.

Extraction of Gold

Bromine acts more energetically than chlorine, and has also been employed in the extraction. The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine.
