Prepare a mixture by adding to the sulphide gold-arsenic-antimony concentrate or ore ammonium chloride NH 4 Cl or ammonium fluoride NH 4 F or their mixture. The mass ratio of the concentrate or ore to the chloride and/or ammonium fluoride is 10:0,3-3,0.

silver ore arsenic The principal Canadian production of white arsenic has been from the silver ores of Cobalt, Ontario, and the gold ores of Ontario, British Columbia, and Nova Scotia. A large amount of arsenic, recovered from the gold ore of the Yellowknife camp in the Northwest Territories, has had to be buried securely in underground openings to get rid of it.

Silver mining is the resource extraction of silver by mining. Silver is found in a native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite (horn silver, AgCl), and galena (a lead ore often containing significant amounts of silver).
