| 摘 要： | 本文对贵州某高硫铝土矿中硫的迁移途径和影响硫溶出率的因素分别进行了研究。结果表明：在高硫铝土矿溶出时,解离的黄铁矿先溶出,被铝土矿包裹的黄铁矿在氧化铝溶出后期才溶出,且溶出量较小；硫溶出率受黄铁矿粒度较细、解离度低、溶液成分和溶出条件等因素的影响。

| Abstract: | In this paper, sulfur migration path and influencing factors of high sulfur were researched. The main conclusions of this article are as follows: when the high sulfur bauxite was dissolution, liberated pyrite is firstly dissoluted, the wrapped pyrite with bauxite is lately dissoluted, and the dissolution rate of sulfur is smaller. Sulfur dissolution rate are affected by the smaller pyrite particle size, low liberate degree, solution composition and the dissolution conditions. |

| Keywords: | high sulfur bauxite sulfur dissolution rate pyrite liberate degree |
