Roasting Arsenic Antimony Ores - 911metallurgist

2016-11-18  Roasting Arsenic Antimony Ores. The difficulty of roasting arsenical and antimonial ores may be avoided by taking ore, 1 A.T. ; red lead, 1,000 grains; sodium carbonate, 500 grains; potassium ferrocyanide, 550 grains, with a cover of salt or borax. The button is scorified, together with the matte formed, before cupellation.

Mapping the evolution of international antimony ores

Nevertheless, the global supply of antimony ores faces problems of severe shortage and highly concentrated mining from a mid-to-long-term perspective (Henckens et al., 2014; Patiño Douce, 2016). Most countries must obtain antimony ores through international trade for the uneven geographical distribution of antimony ores.

Smelting and Roasting Ores to recover gold, silver and ...

2014-6-26  The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
