However this “burning” or roasting of the sulfide ores does work well to convert rebellious ores into a more free milling state allowing the values to be extracted Exact temperatures used in roasting vary and excessive temperatures can cause problems including melting the sulfides before they can oxidize... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.

Here the first miners found rich oxidized silver chloride ores on the surface some of them running as high as 1000 ounces per ton That surface ore presented no real problems in milling so the miners installed the Washoe pan process already in use at Virginia City and started to pull the silver out of their ores
