Purification of copper - Finishing

Purification of copper sulfate by plating is a "maybe". Assuming that you are in an acidic condition, Dissolved copper sulfate will give an acidic condition, many trash metals will plate out also. The key to purification is to use the lowest current that will plate out the copper and not the tramp metals. This will be about 1/2 an amp per sq ft ...
