摘　　要：根据铅锌锑金属具有易挥发的特征，研究了金属硫化矿物在有ＣａＯ存在的条件下，用水煤气或氢气低温直接还原（８５０—９００℃），同时固硫，继而高温挥发一步获得金属或合金．Lead, zinc and animony sulfide minerals were directly reduced by water gas of hydrogen in the presence of CaO in the temperature range 850 - 900℃. At the same time, sulfur was fixed by CaO toform CaS. Then metals or alloys could be obtained by high temperature evaporation due to the volatility of Pb, Zn and Sb metals.

关 键 词：直接还原 硫化矿 硫化铅锌锑矿 冶金 金属矿化矿
