锌精矿沸腾焙烧,用之于湿法炼锌工业,已取得了较丰富的经验。对于火法蒸馏过程来说,仍存在着如改善烟尘质量,降低烟尘率,改进焙烧矿物理化学性能等一系列问题。为此,我局进行了锌精矿制粒沸腾焙烧的试验。现将试验结果介绍于下:试验是在0.5米~2的沸腾炉中进行的、所用粒矿的化学成分为(%):Zn51.24、Pb1.12、Cd0.25、S28.74、As0.31、Fe6.21、CaO2.25、SiO_21.64。粒矿的粒度见附表。
Zinc concentrate boiling roasting, used in zinc smelting industry, has gained more experience. For the fire distillation process, there are still a series of problems such as improving the quality of soot, reducing soot and dust, improving roasting mineral physical and chemical properties. To this end, I Bureau of zinc concentrate granulation boiling roasting test. Now the test results introduced in the next: The test is carried out in a 0.5m ~ 2 boiling furnace, the chemical composition of the ore used (%): Zn51.24, Pb1.12, Cd0.25, S28.74, As0. 31, Fe6.21, CaO2.25, SiO_21.64. Particle size of the mine see the schedule.
