Dissolution Method

Electrochemical dissolution method was used to achieve the recycling of waste hard alloy. Tungsten, cobalt powder and cobalt salts can be obtained through the control of suitable conditions of electric dissolution process ,such as cleaning of waste hard alloy, electric dissolution of waste hard alloy, knocking the basket, treatment of cobalt chloride etc. Tungsten and cobalt chloride solution can be obtained directly by this method, and thus to obtain the cobalt powder and cobalt salts. Recovery rate of WC and cobalt were above 98% and 92-95%.
