Carbon in Pulp Plant

Sslurry at a rate of approximately 3.785 cu. m. per minute (1,000 GPM) is placed in contact with activated carbon. A simplified flow-sheet of the CIP Plant is shown in Figure 2. For years it has been known of the affinity of activated carbon to adsorb preferentially the gold and silver in cyanide complex form. This operation takes place in five circular tanks that provide a total pulp

Major Mines & Projects Phoenix Mine

Ore containing gold, copper, and silver values is processed by 1) crushing; 2) semiautogenous grinding (SAG) and ball mill grinding; 3) gravity concentration for free gold; 4) two-stage flotation to produce a copper sulfide concentrate containing copper, gold, and silver; 5) cyanidation; and 6) carbon-in-pulp (CIP) on the flotation tailings to recover gold and silver. Loaded carbon from CIP is

Carbon in pulp Wikipedia

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 applications where the presence of competing silver or copper does not prohibit its use. Activated carbon acts

added during the leach (carbon-in-leach), or after leaching (carbon-in-pulp). Once the dissolved gold is removed from the solution, the mill tailings and resulting “barren solution” are pumped to the tailings impoundment. The gold is chemically stripped from the carbon, electrowon from the solution, and melted into impure bars, called doré. When zinc dust is used to recover gold from

01/01/2005· An important consideration related to carbon residence time is that the longer the carbon remains in contact with the pulp, the greater the extent of fouling and the greater the detrimental effect on adsorption of gold (Stange, 1999). Total carbon contact time will be influenced by the number of stages, the amount of carbon in each stage, the mode of carbon transfer and the total rate at which

Carbon in Pulp Gold CIP JXSC Machine

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 best conditions for Carbon In Pulp process in China: PH=10-12, sodium cyanide concentration is not less than 0.015%, the particle size of

Homestake Gold Mine, Ruby Hill, Nevada Mining

Ore explored from the mine is processed on-site by zero-discharge heap leach and carbon column facilities. Before the mine was closed in 2002, high grade ore was processed in a conventional mill and leach plant. Low grade ore was heap leached. The recovery plant had a design capacity of 3,175t/d, comprised of 2,358t of low-grade ore crushed in two stages to –19mm and 816t of high-grade ore

The process design of gold leaching and carbon-in-pulp

The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650–750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation. The eluted and regenerated carbon is screened at about 0.8 mm to remove any undersize carbon
