2o
3between reaction, namely reduce Sb with CO
2o
3the flow of oxygen in stove and coal gas is passed into instantaneously by conservative control, guarantee the reducing atmosphere in stove and temperature, weisspiessglanz and reduzate metallic antimony are all in a liquid state, thus the reduction of weisspiessglanz is carried out at liquid-vapo(u)r interface, CO reducing gas is produced by dispersion solid carbon gasification in the melt simultaneously, thus comprises the complex process of gas-liquid-solid multinomial reaction during weisspiessglanz reduction reaction.But it is lower to put forward the efficiency of antimony to antimong-containing material in prior art, and cost is higher.
