Processing Of Antimony Minerals By Oand Idizing And Reducing

A New Pyrometallurgical Process for Producing Antimony .

Antimonial dust is a by-product of lead smelting and an important material for extracting antimony. A new pyrometallurgical process for producing antimony white from the antimonial dust is reported. The process mainly consists of three steps, which are reduction .

smelting process for antimony

The process for treating antimonial lead which comprises softening the lead, reducing and smelting the antimony slag therefrom to metal, removing tin and arsenic from said metal, concentrating same into a high antimony product and euitectic metal, treating the high antimony product in a fuming furnace thereby yielding antimony oxide, an .

Geochemical Factors Affecting the Behavior of Antimony .

At moderately reducing conditions, antimony speciation is dominated by the hydrolytic species Sb(OH)3º (aq) at pH values from 2 to 12. The concentrations of antimony in soils and sediments are likely controlled by adsorption reactions, but very little is known about the adsorption/desorption behavior of Sb(V) or Sb(III). Antimony

Redox - Wikipedia

Etymology "Redox" is a portmanteau of the words "reduction" and "oxidation". The word oxidation originally implied reaction with oxygen to form an oxide, since dioxygen (O 2 (g)) was historically the first recognized oxidizing agent.Later, the term was expanded to encompass oxygen-like substances that accomplished parallel chemical reactions.
