为了综合利用黄石地区的白钨矿源,结合矿源特点(其成份如表1),通过试验,我们拟订了工艺流程,如流程图所示。此工艺的特点是:.采用负压冷却回流酸分解白钨矿提高了酸的利用率,废酸中的酸度约提高20克/升,提高了除钥效果,消除了对大气的污染。 2.高铂钨矿经S000c焙烧后,再经上述酸分解,除铂率
In order to comprehensively utilize the scheelite source in Huangshi area and combine with the characteristics of the ore source (its composition is shown in Table 1), we have drawn up the process flow through the experiment as shown in the flow chart. The process is characterized by :. The use of negative pressure cooling back acid decomposition of scheelite to improve the utilization of acid, the acidity of the waste acid increased by about 20 g / l, improve the key removal effect, eliminating the pollution of the atmosphere. 2. High platinum tungsten ore after S000c roasting, and then by the acid decomposition, in addition to platinum rate
