Copper Arsenic Partial Roasting

Special equipment is used for cooling and precipitating arsenic trioxide, which can be produced to a very high purity. For copper concentrates, partial roasting is used as a pretreatment step prior to the flash smelting process. • Arsenic elimination from concentrate: 12% to < 0.3%. • Antimony elimination from concentrate: 1.2% to < 0.2%.

Roasting Arsenic & Antimony Ores

 · 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.

Mines

 · Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.
