Gold CIP Production Line. Process Introduction. CIP Carbon in pulp process is a high efficient method to leaching and recovering gold from gold ore, The most different from CIL process is in CIP process, gold leaching and adsorption are separated, first leaching, and then adsorption. Now it is being replacing by CIL process progressively.
CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using otation and or gravity circuits. Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density.
CIL gold processing is an efficient, environmental, energy-saving and economic gold recovery process. Xinhai undertook many CIL processing plant like Tanzania 1200tpd gold project.
