几年来,对某地铜钴矿曾进行了多种冶炼流程的试验研究工作。经过各方面的比较,得知,采用以硫酸为硫酸化剂的硫酸化升温焙烧是合理的。为了实现这个工艺过程,采用何种冶炼设备是值得认真研究的。早在1961年曾进行过100公斤/日的竖炉扩大试验。 Over the past few years, a certain copper and cobalt mine has conducted a variety of smelting process of experimental research. After all aspects of comparison, that the use of sulfuric acid as sulfating agent heating roasting is reasonable. In order to achieve this process, which smelting equipment is worth serious study. As early as 1961, a shaft furnace expansion test of 100 kg / day was carried out.
