AARL Carbon Stripping System Operation: Elution

Mar 31, 2016 The Ok Tedi plant had a nominal design throughput of 24 tonnes of carbon per day. The design provided for two 24 tonne per day columns to give 100% standby capacity. Being the first commercial continuous elution column built by Bechtel it was very conservatively sized.

contains gold from the previous strip in the form of gold cyanide complex ions. This is not a problem though, as most of the gold on the carbon will still desorb into this solution, leaving perhaps only 30% of the gold on the carbon. The solution from this stage also reports to the electrolyte tank (tank 8 or 38). • Water Elution Stage

of the AARL process is the ability to strip a batch of carbon to low gold residuals in an 8 hour shift. This offers the potential of either designing for multiple stripping cycles each day and reducing equipment sizes in new plant design, or increasing daily capacity in

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

The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1 500. A portion of the loaded carbon is periodically removed from the first

Aug 01, 2018 The control in this preliminary work was a strip solution consisting of a 2% caustic solution. In order to compare one test strip run to another, a means of quantifying rate was required. Each gold assay result on the elution curve was converted to % of gold remaining on the carbon.

If I decide have a gold strip without cyanide, could I reach the minimum gold elution efficiency? For example: Not lower than 95% If I decide have a gold strip without cyanide, what about the gold content on the desorbed carbon? For example: The gold content is lower or greater than 40 ppm I think, that in AARL, and ZADRA process, caustic and

Electrowinning ScienceDirect

Jan 01, 2016 Electrowinning is most often used to recover gold and silver from eluates produced by the elution of activated carbon. Some of the practical considerations involved in the design and operation of gold electrowinning cells are described in this chapter, including cell types, bullion removal, and special applications such as electrowinning from gravity concentrates, and sulfide oxidation

Apr 01, 2020 The condensate is pumped back to the top of the carbon bed and is sprayed on the carbon. Typical strip times with glycol are 24 to 36 hours. Today, many options are available to the recovery plant designer and operator for the stripping of gold from carbon. These samples should be analysed for Ca plus Mg and then the totals plotted versus time.

Caustic cyanide carbon pre soak prior to elution for

My challenge is that the elution is not stripping the carbon entirely. There is some 400 grams of Copper and 200 grams of gold left in the carbon (500kgs) after the elute. The elute is being done at a company offering such services. The Gold won to the electrowinning cell is about 300 grams.

This assures a rapid interface between the carbon and the gold loaded cyanide solution. Granular, hard carbon is used, in the size range of 10-16 mesh. The carbon is then removed by screening, across a carbon screen, allowing the liquid and finely ground ore (-100 mesh) to pass through easily, and retaining the carbon on the screen.
