Electrowinning Cell – for safe and easy metals recovery

Generally used with gold and silver-bearing cyanide solutions, our cells have also been used successfully with non-cyanide metal-bearing solutions. We offer cell sizes from 50 to 150ft of cathode equivalent volume, normally ranging from 500 to 2000 applied amps per cell, as shown in the table below.

Electrowinning Mercury in Gold Pregnant Solution

at 25° C. Gold extraction was completely suppressed at 25° C. Decreasing the temperature from 60° to 25° C at this potential had a much greater effect on extractions of all three metals than the temperature decrease at 3.0 V. Differences in electrowinning from mercury-gold and mercury-silver solutions were not positively determined by these ...
