Kraft Pulping and Recovery Process basics

Gold on carbon/gold in solution ratios of >1000:1 are achievable in many cases. The distribution of that carbon between the stages (within reason) is irrelevant. The concentration of carbon in the pulp varies with the size of the tanks, so it is irrelevant. Gold extraction efficiency is determined by:

Carbon in Pulp

Carbon in Pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing gold or silver does not prohibit its use.

Paper production process | Fefco

History. A precursor of the Kraft process was used during the Napoleonic Wars in England. The kraft process (so called because of the superior strength of the resulting paper, from the German word Kraft for 'strength') was invented by Carl F. Dahl in 1879 in Danzig, Prussia, Germany. U.S. Patent 296,935 was issued in 1884, and a pulp mill …

Carbon In Pulp Process In Gold Recovery Ppt

The pulp produced is defiberized in refiners, screened and washed before being sent to the paper mill. In the paper mill the pulp is mechanically treated in beaters to improve fibre-to-fibre bonding and the strength of the paper. The pH level of the pulp slurry can be adjusted in some cases to facilitate the paper production.
