Q: Does anyone know of an electrowinning instrument that will plate (heavy plate) rhodium and iridium? I have both in solution. (Solution content = 262.9 oz/ton of iridium; 14.9 oz/ton rhodium.)
If I have precious metals in solution in bulk, say 620 to 1,000 gallons, is there a facility to extract the precious metals out? If so, can each be isolated?
