Pregnant Solution Recovery

How It Works

Direct electrowinning is one of the pregnant solution recovery methods available and is most appropriate for high grade, low volume pregnant solutions. Gekko’s electrowinning cell has been specifically designed to handle high silver-containing solutions and is highly recommended. Gekko also use OEM cells, when appropriate.

For lower grade pregnant solutions, a resin-based, carbon-in-solution or zinc precipitation (Merril Crowe) process, as part of the overall flowsheet design, is suggested.

Resin columns, such as the G-REX, are good for treating flotation solutions or preg-robbing ores because they are simple to use, affordable and are not fouled by flotation chemicals.

A carbon-in-solution process is best for treating high volume slurries, while zinc precipitation (Merrill Crowe) is great for high volume solutions.
