carbon in pulp process in gold recovery ppt

A theoretical study of the carbon in pulp process for gold ... 1. Introduction. The carbon in pulp process for gold recovery involves treatment with cyanide under aerobic conditions at high pH, to give the Au(CN) 2 − ion, which is then recovered by adsorption on carbon, followed by elution of the Au(CN) 2 − in caustic solution and electrowinning of the gold.

Pulp and Paper Manufacturing Process in the paper industry

Refiner pulp and thermomechanical pulp are produced by chips. These chips are ground by passing them through rapidly rotating in both processes. In the second stage after refining, the pulp is screened, cleaned, and most of the process water is removed in preparation for paper making.

Effect of activated carbon on the thiosulfate leaching of gold

 · The addition of fine carbon to this test did not affect gold recovery significantly; in fact, gold recovery decreased from to % when carbon was added to the thiosulfate leach. For the purpose of this work, the main difference between sample S3 and samples S1 and S2 may be the carbon content in each ore (besides the differences in mineralogy).

USA Recovery of gold by a carboninpulp process . A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column

How is Gold Made

Carboninpulp. A recovery process in which slurry of gold ore, free carbon particles and cyanide are mixed together. The solution is passed counter current through a series of tanks containing activated carbon particles. Gold has a natural affinity for carbon and the carbon adsorbs the gold as it passes through the circuit.
