Apr 02, 2016· In all plant circuits, the carbon activity quickly deteriorates from stage to stage but the reasons why it should do so are complex. It is known that the carbon activity is enhanced by lower pH, higher temperature; the presence of Ca2*, Mg2*, Na*; and .

ELUTION & CARBON REACTIVATION 9999 Elution Circuit Components Elution Column The elution column is a 10m high by 1.2m diameter mild steel rubber lined pressure vessel (rated to 350kPa). Having a high 'length to diameter' ratio enables solution to flow evenly through the bed of carbon without short-circuiting or 'tunnelling'.

The elution flowsheet differs from plant to plant, and some of the steps . Two stage stripping of gold with thiourea solution (80 g/L containing 25 g/L H2SO4) .. and biochars is a major consideration for cost effective sorbent materials.

Copper loads onto carbon to a certain extent even when adequate levels of free cyanide is maintained in solution, and the amount of loaded copper is often equivalent to or greater than the amount of gold loaded. However, copper could be eluted from the carbon with cyanide solution at room temperature prior to gold elution at high temperature(5).

process. Experimental runs on the plant scale did prove that the first three parameters are the predominant parameters that maintain base metals in the carbon during the elution and therefore assist in the improvement of the fineness of the final product. Recommendations were made to

The carbon will beadvance d counter-current to the pulp by air lifts. Loaded carbon from the first tank will be recovered over a loaded carbon screen and directed to the elution circuit. The pulp from the last CIL tank will be directed to cyanide detoxification. The elution circuit will be a split AARL circuit with a 2 t acid wash and elution ...

Many gold plants process ores containing traces of mercury, but the deportment of mercury through the entire plant under different operating conditions is poorly understood. It is known that generally mercury follows gold through the cyanide circuit (Zárate, 1985) and loads onto the activated carbon, but only partially elutes with the gold.

Elution & Acid Wash Columns. Elution and Acid Wash Columns can be supplied as separate pieces of equipment to either integrate into your own system design or as replacement items for an existing installation. They are designed and manufactured to AS1210, ASME VIII Div I (U & non-U coded) and EU Directives (CE marked).

Elution of AM-2B resin is similar to that of Minix; but a longer elution time seems to be required (Bolinsky and Shirley, 1996).The process includes a series of elutions, contacting the loaded resin with different solutions. The elution flowsheet differs from plant to plant, and some of the steps described below are optional.

Carbon-in-pulp was used to extract gold and silver from the solution. After elution with thiourea–butanol and cementation with zinc dust, the final PM concentrate assayed 45% Cu, 30% Ag, and 0.4% Au. The process was piloted at a scale of 1 t/d of calcine by Noranda (Rosato et al., 1990).

of plant upset conditions such as poor elution/regeneration, carbon poisoning, carbon loss through breakage or screen rupturing. APPLICATIONS The SGS CIP/CIL model can be used for feasibility or production stage projects. the optimum design criteria and it allows clients the opportunity to test changes to the circuit without actually making the

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.

simulation design packages, so as to arrive at the most appropriate process route. the programme offers a complete gold process testing package for: • refereeing routine samples. • preliminary feasibility studies. • evaluation and design of recovery circuits using carbon and resin adsorption, elution.
