the CIP can be stripped together with gold in the elution process. Depending on their concentration in the pregnant solution, cathodic deposition occurs. Base metals that have not been stripped during the elution will build up in the carbon and will affect the gold loading in the CIP process.
I also have Gold processing experience and am currently employed as a Graduate Metallurgical Engineer at Harmony Gold Doornkop Plant. In this role I am gaining experience on SAG Milling, Thickening, Cyanide Leaching as per Carbon in Pulp process, AARL Elution type ElectroWinning.

Salares Norte is scheduled to start production in 2023. South Africeadquertered Gold Fields completed a feasibility study for the project in early 2019 which included a maiden mineral reserve containing million oz of gold and of silver.
South Africeadquertered Gold Fields completed a feasibility study for the project in early 2019 which included a maiden mineral reserve containing million oz of gold and of silver. The feasibility study envisages an openpit mining operation with an initial mine life of years, producing 450,000oz of gold equivalent per year ...

This is an excellent starting point to commence elution optimisation. Optimisation of the 125°C AARL elution circuit at a small high grade gold mine in PNG in 1996 increased the weekly stripping rate from 6 to 21 strips/week. This facility had been badly bottlenecking the rest of the plant as it regularly campaigned up to 30gpt Au and 200gpt Ag.
May 01, 1994· The influence of temperature on the equilibrium adsorption of gold and hydroxide ion at elution conditions was examined. Experiments were conducted for both single and multiple solute adsorption of gold and OH − ion at the temperaturesbetween 80 and 120°C. Two models were employed to model the equilibrium adsorption of each solute at the single solute level.
Jun 25, 2019· Our Client operates a worldclass mining operation in an overseas location and requires two experienced Senior Metallurgists to join their technical will bring at least 5 years of operational experience from gold or base metals operations and be looking for the challenge of using your technical expertise to provide direction with your training in plant optimisation, flotation and SAG ...
Comparison of AARL and High Pressure Zadra Stripping: Why one Carbon Elution Process Works Best (English) Johnson, G. / Third, B. / Randol International
conditions, elution (desorption) of gold from the carbon occurs. The main factor that makes desorption or stripping a simple process is the fact that gold will only adsorb onto carbon at low temperatures. If the temperature of a solution and carbon mixture is increased, the gold will readily desorb from the carbon into the solution. Temperature
Jan 01, 1991· A preliminary model for the AARL elution process is also described. The model is based on the assumption that the elution behaviour of gold is dominated by the changing sodium concentration during the washing cycle of this process. The model was fitted to data obtained from an industrial elution .

This article serves to discuss the fundamental aspects of gold recovery utilizing the CarboninPulp or CarboninLeach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as

Aug 01, 2017· 1. Introduction. The governing method for gold ore processing has been cyanide leaching since the late 19th century (Marsden and House, 2006).After decades of active development of the process for various types of ores and concentrates, there are several different hydrometallurgical flowsheets for cyanide leaching.
Jun 25, 2020· The large Downstream Gold product line project comprises three complete process Islands: a Merrill Crowe, an AARL elution circuit and a Refinery. The process plant will treat 2 000 000 tpy of ore and is expected to produce an average of million oz of silver and 286 000 oz of gold annually during its first seven years in operation.
Platinum and palladium elute from activated carbon almost to completion in 4 to 5 bed volumes at 80°C, while the elution of gold at this temperature is slow, with a significant amount of gold ...
