Zeev, <then why smelt them?>> It's a method of concentration and refinement. I understand the basic process to be the following: 1. Mill the ore. 2. Leach the ore. 3. Precipitate precious metal salts or compounds. 4. Dry the precipitate. 5. Smelt the precipitate, diffuse the precious metals into copper. 6. Chemically dissolve the PM loaded copper (leach, pregnant liquor). 7. Modify the pregnant liquor chemistry such that the precious metals are preferentially absorbed on ion exchange resin. 8. Ship the loaded resin to refiner, get big check. That's my simple understanding of the process. If my understanding is correct, there seems to be a number of steps where metal is in solution. Even if not in solution, solution can be easily realized with a Gilbert chemistry set. Is my understanding wrong?
