Washing Activated Carbon - 911 Metallurgist
2016-6-7 The objective in the acid wash circuit is to remove scale build-up on the carbon, thereby opening up the activated carbon micro-pores. The step is important to maintain the carbon’s ability to recover additional gold as well as maximize the surface exposure that will improve the overall gold elution efficiency in the downstream processing.

Demonstration of the CESL Gold Process
2015-11-20 The carbon acid wash was operated on a batch basis and ventilated to a scrubber to remove any volatilized cyanide. The gold and silver on the acid washed loaded carbon was desorbed into solution by a caustic cyanide elution in a mild steel strip vessel at 135°C.

Acid Washing – Denver Mineral Engineers
Acid washing has proven to be a very cost-effective means of maintaining the activity of activated carbon. During operation, carbon will typically become fouled due to an accumulation of precipitated mineral salts. This reduces the carbon particle area available for gold and silver adsorption.

2009-8-27 carbon pores. The acid washed carbon is then eluted. This is done by contacting the carbon with a solution of sodium cyanide (0.1 to 2% by mass) and sodium hydroxide (0.1 to 2% by mass) at high temperatures (90–120°C). This results in the reversal of the adsorption process with most of the gold desorbing from the carbon back into solution. This produces

Carbon Stripping – Denver Mineral Engineers
With the AARL process, elution is normally proceeded by acid washing the carbon. Acid washing is used with all of the other stripping systems, but it is mentioned specifically with the AARL procedure, because AARL systems generally use the stripping vessel to acid wash and acid washing is, therefore, controlled as part of the stripping sequence ...

The Issue of pH Adjustment in Acid-Washed Carbons
2001-5-15 Any activated carbon that is not acid-washed usually produces an initial effluent with a pH greater than 7. The actual rise in pH depends on several factors such as the ash content of the starting material, total dissolved solids (TDS) of the influent water, and pH of the influent water. The observed effluent pH can be much higher than 7, new ...
