为了解决有色冶金过程中普遍存在的污染和耗能高的问题,我们在对硫化物直接氢还原的方法及 Amax 法做了对比和研究后,以江西德兴铜精矿为原料,针对该原料铜、铁、硫含量高、碱性脉石少的特点,提出采用全氧化焙烧、焙砂经还原后用盐酸浸出分离的新流程进行处理。 In order to solve the problem of high pollution and high energy consumption in the non-ferrous metallurgy process, after comparing and studying the direct hydrogen reduction method of sulfide and Amax method, taking Dexing copper concentrate in Jiangxi as raw material, Copper, iron, sulfur content is high, less basic gangue, proposed the use of all-oxidation roasting, calcine after reduction by hydrochloric acid leaching and separation of a new process for processing.
