Placer Gold Recovery Methods - California Department …

The concentration of placer gold ore consists of a combina-tion of the following three stages: roughing, cleaning, and scav-enging. The object of concentration is to separate the raw ore into two products. Ideally, in placer gold recovery, all the gold will be in the concentrate, while all other material will be in the tailings.

Gold recovery with ion exchange used resins - ScienceDirect

The cationic resin could not recover gold from the solution and was then eliminated as a candidate for the job. The measured concentration histories in the solutions in contact with the anionic resins are shown in Fig. 4, while in Fig. 5 the amounts recovered by the resins, calculated with Eq. (5), are shown.These figures clearly show that, when NaOH is used as regenerant, …

Gold recovery from cyanide solutions with a new fibrous ...

In a resin-in-pulp process for the recovery of gold cyanide from a very dilute solution it is desirable that the resin should exhibit the ability to load gold at the natural pH of the leach liquor and be stripped by an aqueous alkali. The present work describes the results of gold cyanide adsorption by new ion-exchange hollow fibers prepared by the amination of sulfochlorinated polyethylene ...
