Silver ore processing?
The ore is from cobalt Ontario, so I believe it is pure silver metal with cobalt arsenide, silver arsenide and nickel arsenide So I would avoid the hcl wash on my 100 mesh crush as it would convert too much silver to silver chloride, thus the silver chloride would burn off in the furnace. Thanks for the insight!

How to Process Gold Ore? 4 Gold Processing Steps
Method #2: Gold flotation process. Flotation is a widely used beneficiation method for rock gold ore. The flotation process can maximize gold enrichment into sulfide minerals, tailings can be directly discarded, and the beneficiation cost is low. The gold flotation process mainly includes four stages: dosing, agitation, aeration, and scraping.

Waste Management in the Gold and Silver Industry
The average grade of gold ores has been falling over the years. Between 1830 and 1900, the average grade of gold ore was around 20 g/ton and in 2000; it had dropped to around 3 g/ton (Muller and Frimmel 2010). Gold mining companies are processing lower grades of ore as the higher-grade ores are getting depleted.
