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?

The Suction Gold Dredging Fight Continues in California
July 2009
The story is similar to what has played out over the past several years. The Karuk Tribe of northern California, with the support of several environmental and fishing groups, sues the California Department of Fish & Game in an attempt to stop suction gold dredging in the state. At the same time, they find a state legislator sympathetic to their cause and persuade the legislator to introduce a bill to stop suction gold dredging.
