QUESTIONS ON ELECTROWINNING

Remco Engineering question on electrowinning treatment. A low voltage direct current is applied through the solution and metal ions are reduced at the cathode and If the proper segregation is used, little or no maintenance is required between loads except for monitoring the operation. Gold is plated at very high pH.
