| 摘 要： | 针对现有辉钼矿氧化焙烧工艺生产效率低、设备结构复杂、炉料容易烧结、二氧化硫污染严重等不足,提出一种熔池熔炼辉钼矿的新方法.为了得到不同温度下辉钼矿在白冰铜中的溶解度,用干化学法合成硫化亚铜,并用步冷曲线法测定了Cu2S-MoS2二元系相图.实验结果表明,在MoS2质量分数为0～4.48％的范围内,Cu2S-MoS2二元系为简单的二元共晶体系,共晶温度为(1117.0±3.0)℃,共晶组成为(1.70±0.20)％MoS2;当MoS2含量超过4.48％时MoS2和Cu2S形成固溶体.在铜熔炼温度范围(1200～1300℃)内,白冰铜能够溶解辉钼矿,在1200℃时溶解度达到14.8％.

| Abstract: | A novel method, bath smelting process, was developed to treat molybdenite concentrate aiming at the existing problems of traditional process. To understand the dissolving behavior of MoS2 in white matte, the binary phase diagram of Cu2S–Mo2S was measured by the cooling curve method. The result shows that this system is a simple binary eutectic with a eutectic temperature of (1117.0±3.0) °C and a eutectic composition of (1.70±0.20)% MoS2 in mass fraction. When the MoS2 addition exceeds 4.48%, MoS2 and Cu2S can form the ternary compound containing CuMo2S3 or Cu2Mo6S8. In the temperature range of copper smelting, 1200–1300 °C, molybdenite can dissolve in the cuprous sulfide. At 1200 °C, the solubility of molybdenite can reach 14.8%. |
