Fort Knox operates two ore processing lines: a mill operation consisting of crushing, grinding, agitated cyanide leaching, and a carboninpulp (CIP) circuit; and a runof mine valleyfill cyanide heap leaching operation where gold is recovered using two parallel carbonincolumn (CIC) circuits.

Sep 01, 2011· How the Gold Business Operates. Most of the gold in the world is produced by a small number of countries: China, South Africa, the United States, Australia, Russia, Canada, Peru, Indonesia. Gold mines produce rough gold, called a dore bar. These bars are typically about 80 percent pure gold.
The New Process. The resin containing the gold is sent through an elution process, where it is stripped of the metal. The gold solution travels to the refinery for an electrowinning process. After the gold is separated, the barren solution is sent back to be reused, Eiselein said.
Jul 09, 2015· The elution process uses caustic soda and cyanide in a pressurized column at 110°C to strip the gold off the carbon. Once this step is complete, only the spent carbon is left behind. The carbon is then rinsed in water and sent for regeneration via the carbon regeneration kilns.
A process of elimination will usually enable you to pinpoint the specific cause and correct the problem. How to Prevent Mobile Phase Problems Low sensitivity and rising baselines, noise, or spikes on the chromatogram can often be attributed to the mobile phase. Contaminants in the mobile phase are especially troublesome in gradient elution.
Electrowinning is compatible with the elution technique and provides a simple and effective method of recovering the gold from the eluate. The composition of the eluate does not affect the electrowinning efficiency much and it is therefore possible to operate both the elution and the electrowinning at their optimum efficiency.
The CIP and CIL processes use granulated activated carbon that is mixed with the pulp, composed of ore and water, and after it has been loaded with aurocyanide ion, the rich activated carbon is pumped out into the adsorption circuit and sent to the elution process.
Palladium, gold and platinum are recovered during the cyanide leaching stage. The pregnant leach solution was evaluated for potential carboninpulp adsorption and subsequent elution similar to gold processing. The kinetics of adsorption and elution compared well with gold adsorption and elution.

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. The changes made to the operating standards, the response of the circuit to these changes and the final Circuit layout and operating conditioning resulting in a 90% gold recovery are discussed.

Our business covers more than 100 countries and regions around the world, many famous companies choose us, we have won praises from customers with products and services. Elution And Electrowinning For Gold Processing Plant.
Elution heating system design. The proper design of such a system is key to the consistent production of gold. The Applied Heat system uses thermal oil, which is heated up via the THERMOMAT heater at temperatures anywhere up to 300ºC, which is circulated via a shell and tube eluant / oil heat exchanger, to heat a steady eluant flow.
Jun 29, 1993· A process as claimed in claim 1, 3 or 4, wherein the acidic solution is a leach solution obtained in the final recovery step of the acidified thiourea leaching of gold ore or concentrate in the presence of carbon followed by elution of the carbon by thiosulfate or thiocyanate.
In this paper,three kinds of techniques and equipments of elution of gold from carbon are evaluated. The characteristics of elution of gold from carbon by the ethyl alcohol distillation process without cyanide are introduced. A few technical problems related to choice of techniques and equipments are discussed.
Nov 23, 2015· South Africa – AIM listed African gold producer Goldplat plc has commissioned the first of the 4 t elution columns acquired from surface gold miner DRDGold at the Goldplat Recovery operation on the East Rand of Johannesburg. The completion of this project, on schedule, is .
includes planning and preparing for the elution process, starting up equipment in sequence, operating and monitoring equipment, conducting housekeeping activities, and shutting down in sequence and/or isolating equipment.
