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 Stonewall Jackson Mine, San Diego County, California
July 2001
For obvious reasons southern California is not known historically for its gold mines. Gold production was concentrated heavily in the Sierra Nevada foothills in the northern part of the state. However, the high mountainous region of eastern San Diego County was the site of a number of productive hardrock gold mines, notably in the late 19th century.

The Collaboration
April 2003
When Jimmy stuck his head in my office that morning, little did I realize that his question would lead to a surprising collaboration. “Hey, Slusher, did you know that the Rock Shop out east of Deming has a pile of our ore in their back yard?”

Remote Mining Camps of Yuma County
October 2006
The remote desert of southwestern Arizona was an attraction only because of the gold and other minerals that were found there. Certainly the weather was not a draw! The early mining days were tough—the mines were a long way from supplies, and hostile Indians made travel in the area extremely dangerous.
