Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carbon in pulp circuit CIP.
Carbon in pulp 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 presencepeting silver or copper does not prohibit its use Activated carbon acts like a sponge to
The efficiency and recovery of chemical processes involved in gold extraction is exclusive to the mineralogy of the ore. Gold may exist as free nuggets or particles in alluvial or elluvial deposits or as native metal in other minerals. The gold mineralogy of any given ore deposit is unique to all others due to variations in the following:
Gold ore is a type of ore that can be obtained by mining gold ore rocks, requiring a Mining level of 40 or higher, and granting 65 experience. Gold ore can be smelted into gold bars through the Smithing skill, requiring level 40 Smithing. Gold bars can then be crafted to make various pieces of jewellery. The Crafting Guild is the best place to mine gold ore for non members, requiring 40
The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen. Next, the gold adsorbs to the activated carbon. Finally, the carbon andplex is sent to elution where it is washed, and transferred to electrolysis where the gold

The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately 0.8 gram per tonne gold and 0.11 per cent copper.
A number of gold processing plants in Western Australia have nickel in their ores, leading to significant levels of nickel on their loaded carbon. The presence of nickel during leaching, adsorption and elutionmay have detrimental effects on cyanide consumption, carbon inventory requirements, stripping costs, electrowinning efficiencies and may contaminate the gold bullion.
All of the stripping operations are carried out at 5560 °C and atmospheric pressure. The original design of the stripping section required up to 288 h 12 days for elution before achieving gold recovery. In the 1980s, a new stripping technique was developed, which takes from 12 to 24 h, a considerable improvement over the original design.

2.1 The chemistry and factors affecting elution Activated carbon is used to adsorb gold that is leached by cyanide solution. The gold is then stripped from this loaded carbon by means of elution to form a concentrated eluate which is then processed for gold recovery by electrowinning. Essentially elution is the reverse of the adsorption process.
The efficiency and recovery of chemical processes involved in gold extraction is exclusive to the mineralogy of the ore. Gold may exist as free nuggets or particles in alluvial or elluvial deposits or as native metal in other minerals. The gold mineralogy of any given ore deposit is unique to all others due to variations in the following:
Activated carbon is aponent in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the goldplex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.
In the early stages of the operation the overall gold recovery achieved averaged 61 and copper recovery was 74 . The plant was experiencing problems in the leach, adsorption, elution and electrowinning sections mainly as a result of the presence of copper in the ore.
20/06/2019· It was not, however, until methods for chemically desorbing gold from loaded carbon were developed, that the process came into widespread use for gold recovery from ore. The Micron elution procedure takes advantage of the enhanced stripping rate achieved with alcohol, but confines the alcohol to the closed stripping unit. Ethylene or propylene glycol are frequently used, rather than alcohol
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.
Elution can be improved by an increase in the thiourea concentration, the acid concentration or the temperature. With an eluant containing 1 M thiourea and 0.5 M H 2 SO 4 at 60 °C, elution efficiencies of more than 99.6 can be effected within four or five bed volumes of eluant.

The Falcon Concentrator is a Fine Gold Recovery Equipment made of a rotating bowl with the smooth inclined wall. The feed slurry enters the bottom of the bowl and gets stratified along the bowl wall. The heavier material settles on the wall while the lighter particles are pushed to the lip of the bowl and discharged as the overflow.
A disadvantage of the use of SBA resins for gold cyanide recovery is the fact that thiourea is a suspected carcinogen, resulting in reluctance by new operations to use strong base resins. Thiourea is, however, readily oxidised and could be safely disposed of. Another disadvantage is that thioureaposes relatively quickly in acidic solution.
gold from loaded carbon were developed, that the process came into widespread use for gold recovery from ore. These procedures allowed the carbon to be recycled for further gold recovery. Today, many options are available to the recovery plant designer and operator for the stripping of gold from carbon.
In heap leaching, the ore is placed on open air pads and the cyanide sprayed over it, taking several weeks to leach down to an impervious base. The solution then pours off the pad into a pond and is pumped from there to a recovery plant where the gold is recovered.

A refractory gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach s
