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?

Lieutenant Henry O. Flipper might well have been correct about the “Santa Fe de Rodríquez” being the name of what is now called Guaynopa. However, an Indian named Agustín de la Cruz, who was associated with Cristóbal Rodríquez, is credited with discovering the mine in 1741. It is probable that the Spanish settlement had indeed been found because of its rather extensive ruins.
