gold elution carbon strip plant design

Elution and Carbon Reactivation - Resource book

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

Carbon Stripping – Denver Mineral Engineers

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 existing mills by stripping on additional shifts each day. Disadvantages of the AARL process include the requirement for high ...

Carbon Elution/Strip System for precious metal recovery

During the standard elution process, the majority of the gold is recovered in the first half of the strip cycle and the remaining time is used to polish the carbon to low absorbed gold values. In our patented FLS-SVT Split-Zadra, as is true for the Split-AARL process, the solution from the polishing time is used as the lean eluate for the next elution cycle. The FLS-SVT Split-Zadra is capable ...

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.

Mesopores (100 Å to 500 Å) these are the pores that branch off the macropores that serve to allow the adsorbates to leave the macropores Micropores (8 to 100 Å) which are of the right size to allow the adsorbates to be strongly

Electrowinning - ScienceDirect

01/01/2016  The elution rate of the gold from the carbon in to the eluate was limited by the relatively low temperature and due to the cell inefficiency, gold that was not plated was recycled to the carbon, further inhibiting the elution rate. These two effects resulted in elution cycle times in the range of 24–96 h. This was a serious problem for operators, who needed to turn their carbon over much ...

Electrowinning Cell – for safe and easy metals recovery

We design our cells and operate them to produce gold and silver sludge on a stainless-steel mesh-wrapped punch-plate cathode. For easy servicing, the cathodes are moved along the buss bar when the cell lid is opened, and the sludge is washed from the mesh and down the sloped bottom to the outlet flange using a pressure sprayer. The sludge is then pumped from the cell to the sludge filter ...

Gold extraction - Wikipedia

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 ...
