Antimony trioxide - Wikipedia

Antimony trioxide Sb 2 O 3 Antimony trioxide Sb 2 O 3 is made with a chemical that comes from the oxidation of antimony metal It is white when cold and yellow when hot Among other properties should be noted that is a flame retardant that is costs that burn when flame is applied

Global Antimony Trioxide Industry Market Research Report

For the treatment of lead-antimony alloys the Harris process is largely employed in England and some other countries In this process the scrap metal is melted with an oxidising alkaline flux Arsenic antimony and tin are then removed by skimming as sodium arsenate antimonate and stannate

antimony production process - essentialgap co za

The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore The antimony in this study occurs as the mineral stibnite Sb2S3 in association with small amounts of pyrite arsenopyrite galena and lead sulfantimonides The gangue is composed largely of quartz but contains in addition a small amount of talc
