Ok I've been doing some more thinking about the electrowinning process. With the cost of electrowinning being relative to the cost of electricity then as long as the cost of electricity is not prohibitive then the electrowinning process should work as well. A 10 cent per KWhr rate equates to about $80 to electrowin an 800lb Dore block. Its easy to scale from there. The cost is not excessive, especially when you consider that this process is used to purify much copper from raw ore. Agreed there are precious metal impurities that help to offset the cost for copper production. It has to be economical at least on a large scale. The equipment to electrowin cannot be too expensive. I could build a unit that should be able to process about 5lbs an hr for about $1000 using a cheap welder and a fiberglass tank as the basis. By using 2 tanks connected with a pipe, I could put the anode in one and the cathode in the other and collect the Oxygen and Hydrogen byproducts of electrolysis as well to use for foundary gasses. A clean water make up system and a circulation pump is probably all else that I would need to make this a potent circuit. Thats all for now, I have to go to class will get back later. Chuck
