CARBON ADSORPTION RECOVERY. Gold cyanide is adsorbed into the pores of activated carbon, resulting in a process solution that is devoid of gold. The loaded carbon is heated by a strong solution of hot caustic and cyanide to reverse the adsorption process and strip the carbon of gold. Gold is then removed from the solution by electrowinning.

Innovative device offers solution to waterless mineral

In the 1970s, a dry process pilot plant was designed to develop a gold deposit in a desert, where water was a scarce commodity. The ground feed was separated into five different plus 200 mesh particle size groups and achieved 90% gold recovery, from a 5 gram per tonne feed.

Innovative device offers solution to waterless mineral

When the price of gold increased from $300 to $1,500 per ounce, the average grades of gold ores mined and processed dropped from 5 grams per ton down to the 1 gram per ton range. To process these lower grade ores, a dry processing system will be required to treat several particle size intervals separately.

PLACER GOLD RECOVERY METHODS Denver Mineral

To day, placer gold production comes from the dredge operating at Hammonton, from large placer mines employing the cya nide process, from byproduct recovery in sand and gravel plants, from small placer mines, and from small dredging op erations in rivers and streams.

Dry Washer   Recreational Gold Prospecting

Dry Washer Recreational Gold Prospecting

Perhaps the most widely used piece of equipment for dry gold recovery, is a dry washer. The dry washer is basically a short, waterless sluice. It separates gold from sand by pulsations of air through a porous medium. Screened gravel passes down an inclined riffle box with cross riffles. The bottom of the box consists of canvas or some other fabric.
