Carbon in the Pulp CIP Plant Consists of the Following Steps: 1. Crushing and Screening After the crushing and screening by the crusher and vibrating screen, the bulk ore （up to 650 mm） can be broken into small sizes （about 10 mm or even smaller). Usually, small or medium-scale mineral processing plants can meet the requirements after two crushing stages and one …

Cyanide Leaching with Carbon or Resin in Pulp. The addition of activated carbon to adsorb gold preferentially to the acivated carbon component in the ore was proposed by T. G. Chapman (1939 and 1950) who recovered the activated carbon by flotation.
The amount of gold and silver lost in tail pulp with the wear of carbon is higher than CIP process. The above introduces the difference between CIL and CIP process. The determination of gold ore dressing process needs …
Recovery of the carbon from the pulp was done by screening or flotation, and recovery of gold from the carbon was done by burning the carbon (a very difficult task) or by sending it to a …
to the gold elution stage. The copper-free loaded carbon was easily treated for gold with very high elution and electrowinning efficiencies of 96 and 98% respectively. A bullion of high fineness (in the region of 98% gold and silver) was obtained and the activity of carbon after elution was reasonably high at 80%

Silver Mining. Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching. Silver Uses. Silver has been used for thousands of years for jewelry and decorative items of all types.

Carbon-in-pulp silver adsoption from cyanide leach slurries of a silver ore by Stuart J Hussey, 1978, Dept. of the Interior, Bureau of Mines edition, in English
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. [1] Introduced in the early 1980s, 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 silver or copper does not prohibit its use.
