Highlights Worldwide gold recovery on activated carbon grew from zero to almost 70% in twenty years from 1980. The stellar attributes of carbon gold plants led to complacency in the industry in designing and operating these plants. Most CIP and CIL plants are overdesigned and operated suboptimally. Optimum design criteria and operating conditions are easily determined with simple test work ...
information on gold carbon in leach plants . Carbon Adsorption In Recovery Of Gold From Cyanide Leach Solutions. It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years, and many papers have been written on the subject. Carbon, as a media of recovery for gold from leach solutions, did not gain ...
Arsenic and antimony do present a larger problem, by reacting with the cyanide and using up all of the excess oxygen, leaving little or no oxygen to effect the dissolution of gold. Carbonaceous gold ores can have the carbon adsorb the gold onto its surface, and as a .
Oct 20, 2014· Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.
Outotec''s cyanide leaching plants are available as gold adsorption directly from the process slurry in carboninleach (CIL) and carboninpulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solidliquid separation by MerrillCrowe and carbonincolumn operations.

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to ...

What is Gold Cyanidation? (with picture) 15 · Processing the ore immediately without crushing it is known as dump leaching. Each process, however, uses cyanide to remove the gold from the ore. Ad. Depending on what other metals are present in the ore, preliminary processes may be necessary to ensure a productive and effective extraction.
A countercurrent, carboninpulp, pilot plant test was made for the adsorption and recovery of gold on minus 6 plus 16mesh coconut carbon from cyanide leach slurries of the jig tailing. The ore was in two lots containing and oz/ton Au and was leached in cyanide solutions containing and pet NaCN, respectively, at pH 11.
