The carbon acid wash cycle takes about 4.30 hours. Acid washing may also help in removing some of the

  • Carbon in pulp Wikipedia

    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.. 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.
