Dry and wet preparation methods are the most popular for antimony trioxide. The dry method involves reducing the crude sulfur trioxide produced by calcining sulfantimonide ore to metallic antimony in the presence of coke and soda as a melting promoter. The wet method involves generating antimony trichloride by leaching sulfur antimony ore with hydrochloric acid and then hydrolyzing it with ...

Get Price· The name antimony was derived from the Greek words, "anti," meaning not, and "monos," meaning alone, because antimony is normally found in complex ore bodies. In ancient times, powdered stibnite was, along with lead sulfide, a principal ingredient of kohl, the thick black paste used by the Egyptians and others as a cosmetic for coloring eyebrows and lining the eyes.
Get Price· This work aims to shed light on the leaching kinetics of antimony from stibnite ore in potassium hydroxide (KOH) solution. Response surface methodology based on central composite design was used to investigate the effect of time, temperature, solid to liquid ratio (S/L), and KOH concentration as independent parameters on the leaching efficiency of antimony. According to the results, time .
