Carbon-In-Pulp. With carbon-in-pulp, the ore is finely ground and the gold is solubilised using a cyanide leach in a series of tanks. The granular activated carbon is added to the leached slurry, where the carbon adsorbs the gold from the slurry solution and is then
Jan 01, 2016 The pump cell combines pumping, screening, and agitation in a single-drive unit with a high rate agitation. The design permits high carbon densities, resulting in short residence times for the pulp. As a result, pump-cell dimensions are much smaller than typical carbon-adsorption stages in CIP or CIL operations.
Carbon in Pulp. 8613879771862. salesjxscmining.com. Inquire Now. Gold Carbon-in-pulp CIP, Gold CIP Production Line. Gold Carbon-in-pulp CIP production line is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.
Schematic diagram of a carbon-in-pulp or carbon-in-leach plant with three tanks, showing the interstate screens IS, the screen at the exit of the first tank S, and the carbon transfer pumps P.
Jan 02, 2013 Following leaching, the pulp flows into the carbon-in-pulp circuit which operates in counter-current fashion. Usually five stages of adsorption are employed. Traditionally, 6 by 16 mesh activated carbon is added to the number 5 carbon-in-pulp tank
The use of activated carbon for the recovery of gold and silver from dilute caustic cyanide solutions has been well documented in recent years 1-9.3 Whether employed in carbon-in-pulp, carbon-in-Ieach, or loading-column proc esses, activated carbon has amply demonstrated its ability as an efficient extractor of precious metals from cyanide

Carbon-in-Pulp CIP and Carbon-in-Leach CIL processes have surface areas of about 1000 m g i.e. one gram of activated carbon the amount of which will occupy the same space as the end of a persons thumb has the same surface area as two football fields. The high surface area is contained in the millions of pores of varying sizes, these being
Sep 01, 2018 The most carbon emission intensive case study utilized an imported Kraft pulp and local chemi-mechanical pulp CMP mixture to make SCP with total GHG emissions of 2646 kg CO 2-eq per ton. The GHG emissions can be mostly attributed to the coal burning to provide electricity and steam for CMP and SCP making 45 .
Carbon-In-Leach. The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation in which the leach tanks are fitted with carbon retention screens and the carbon-in-pulp tanks are eliminated.

After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as Carbon-in-Pulp CIP, Carbon-in-Leach CIL, or Carbon Column CC. Once absorbed, the gold is stripped from the Carbon and the impregnated stripping solution fed into the electrowinning process where the gold is recovered by electrolysis.
