摘    要：本文根据0.2米²的沸腾焙烧炉对铜、铅、锌复合硫化精矿的氧化焙烧和硫酸化焙烧的试验数据,进行了化学平衡计算、分析;提出了实现含铅高的复合硫化精矿高温氧化焙烧的正常作业条件;对下一步的铜、铅、锌分离进行了探讨;并参考文献资料,提出了有关复合硫化精矿直接熔炼的可行途径。

Abstract: All tests were made with flotation complen sulfide concentrate having the following analysis, in wt--pct: 14.57 Cu, 16.52 Zn, 9.52 Pb. The roasting of this concentrate was conducted in a fluidized bed roaster with a bed area of 0.2M². Experimental results showed that the minimum superficial gas velocity for normal fluidization was more than 1.1m. s^-1 at 800℃. Based upon this experimental data the equilibrium gas composition fer oxidizing and sulfatizing roasting of this concentrate was calculated. And the principled flowsheet of hydrometallurgy and direct smelting for treating this complex sulfide concentrate was also proposed.
