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 appli ions where the presence of competing silver or copper does not prohibit its use.
The pulp will be sent into a thickener. The thickener will concentrate the pulp increase the pulp concentration and at the same time wash the pulp. The concentrated pulp will then be washed and bleached by a pulp washer and ground to fine pulp by a paper pulper.
In very simple words a thickener is a machine that separates liquid from solids. It is defined as a method of continuous dewatering of a dilute pulp wherein a regular discharge of a thick pulp…
CIP Carbon In Pulp process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with high-grade silver as well. Generally the proportion of gold and silver should not exceed 1:5.
The thickener 11 receives the barren pulp from the upper end of the column this pulp being passed through a ` ch` screen 12 simply to recover any carbon which may become entrained in the pulp. When the column is in use pulp is introduced through the inlet at the center of the conical bottom end and flows upwardly fluidising carbon in each stage.
The high-efficiency pulp thickener is mainly composed of a circular thickening tank and a rake mud scraper. The solid particles suspended in the slurry in the thickening tank settle under the action of gravity and the upper part becomes clarified water so that the solid and liquid can be separated and deposited on The slime at the bottom of the concentration tank is continuously scraped and
The carbon in the reactor into which pregnant pulp is fed referred to as the first reactor becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon a concen-trating factor of about 1 000–1 500. A portion of the loaded carbon is periodically removed from the first adsorption
