Antimony trioxide Sb2O3 is the most important antimony compound produced Today antimony trioxide is produced by volatilizing antimony metal in an oxidizing furnace It is used in halogen compound ﬂame retarding formulations for plastics paints textiles and rubber Most commercial grades of antimony
5 ERG’s customer buys stibnite ore antimony sulphide This arrives in containers into Sohar port and is delivered by road to the plant After quality checks and blending the ore is fed into the Roaster where it is heated and oxidised with air to form antimony oxide vapour Sulphur dioxide SO 2 is a byproduct The flue gas from the roaster is then cooled
Download PDF 2062838 25 antimony and 20 lead is blown to black copper for subsequent refining to copper and antimonial lead which may be recycled through the process the withdrawn residual metal thereby yielding a high antimony dross suitable for return for the volatilization of antimony oxide 6 The process for preparing antimony
process route Namely these aspects are optimization of the lead refining process towards a more differentiated separation of accompanying elements in the different drosses winning of antimony oxide from the antimony rich fraction and proving the applicability of the product in plastic goods
antimony has 500 in the last 11 years 23 july 2001 23 august 2013 antimony prices antimony is a metal that occurs naturally in the earth’s crust the product is mostly sold commercially as metal ingots or as antimony trioxide powder antimony uses antimony has a number of different uses but is primarily used as a flame retardant 250 000

An improved process for refining lead bullion containing antimony in which the bullion is initially heated in a refining vessel to about 25° F 14° C above the bullion melting point and is thereafter kept molten primarily by exothermic process reactions
Antimony is a ‘critical metal’ in short supply in the world markets Gunn 2014 Mining of antimony ores in Myanmar reached 9000 metric tons in 2014 USGS 2015 establishing Myanmar as a significant global source of antimony ore the bulk of which is exported to China The majority of the antimony ore in Myanmar is in syntectonic quartz–stibnite veins and breccias Type I of Dill 1998
