07/06/2016· The objective in the acid wash circuit is to remove scale build up on the carbon, thereby opening up the activated carbon micro pores. The step is important to maintain the carbons ability to recover additional gold as well as maximize the surface exposure that will improve the overall gold elution efficiency in the downstream processing.
This article serves to discuss the fundamental aspects of gold recovery utilizing the Carbon in Pulp or Carbon in Leach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as
02/01/2013· Gold absorbs onto the activated carbon, which flows countercurrent to the pulp, while screens separate the barren pulp from the gold loaded carbon. Carbon in leach is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg robbing materials
To ensure low gold in tails after gold recovery utilizing carbon, the gold loaded onto carbon must also be low. To ensure a cost effective process, high
Gold Recovery There are several gold processing operations requiring activated carbons: CIP : gold pulp is mixed with sodium cyanide, then is contacted with activated carbon in a series of large agitated adsorption tanks CIL : similar to CIP but leaching and adsorption occur simultaneously
Two types of processes. Chemical Raw materials mixed with acid dried and heated to 650°C. Physical Raw material is firstly charred in carbonisation step then heated to elevated temperatures in the presence of steam to create activated carbon . 9.
It is now the most common method used for the recovery of gold from a cyanide leach solution. Two primary methods, Carbon In Pulp and Carbon Columns probably comprise the most widely utilized techniques for extracting gold, now days. In CIP, the carbon is mixed with the cyanide leach solution, and agitated in the leach tanks, and agitated with the ore while the
01/11/2015· Phenomenological model for simulating Carbon in leach circuit is developed. Multi objective optimization study using NSGA II is performed. Decreasing carbon profile is best for gold recovery from preg robbing ore. Optimal solution for high recovery and profit is presented as Pareto front.
Coconut shell based carbons are the most commonly selected type of activated carbon for gold recovery. This type of carbon boasts numerous characteristics that make it ideal for use in gold recovery, including superior hardness and pore structure. Reactivating Activated Carbon. One of the many benefits to using activated carbon is that it is reusable.
The gold free leach solution is then recycled, while the carbon is processed to remove the concentrated gold. Carbon Fines Removal Filter Press In each of the CIC, CIP, and CIL processes, the gold that has been adsorbed and concentrated on the activated carbon is then recovered from the carbon by elution.
