海南铁矿是我国著名的钢铁原料基地之一,但是,随着采矿工作面不断地扩大和下降,高硫矿石也相应地增多,其中北-主矿的高硫富赤铁矿,约占北-主矿体总储量的21%,平均含硫1.4%左右;南六矿的高硫富赤铁矿,约占南六矿体总储量的82%,平均含硫1.1%左右。这些矿石具有含硫高,含硫酸盐硫高的特点,属于难烧结脱硫的矿石类型。因此,研究硫化物硫和硫酸盐硫的脱除具有重要的现实意义。
Hainan iron ore is one of China’s famous steel raw material bases, however, with the continuous expansion and decline of mining face, correspondingly increased high-sulfur ore, of which North - the main ore of high-sulfur hematite, accounting for about North - 21% of the total ore reserves of the main ore body with an average sulfur content of about 1.4%. The high-sulfur hematite ore from the South Liuli ore mine accounts for about 82% of the total reserves of the Nan 六 orebody with an average sulfur content of about 1.1%. These ores have the characteristics of high sulfur content and high sulphate and sulfur content, and are of the type of refractory desulfurization ore. Therefore, the study of sulfur sulfide and sulfate sulfur removal has important practical significance.
