我厂铜转炉烟尘中含有多种有价金属,但品位较低。近年来,在毛主席革命路线的指引下,为了合理回收这些金属,我们以批林批孔为动力,对原有工艺流程进行了两次较大的改革。最初是用两段锌粉置换,锌粉耗量高达180(公斤/吨烟尘),尽管锌能以硫酸锌形式回收,但锌粉来源较困难。为此,后改用水解富集——P204萃取流程,通过生产实践,该流程仍不够理想,有价金属的富集倍数也不高;另外,流程的第一步 I plant copper converter soot contains a variety of valuable metals, but the lower grade. In recent years, with the guidance of Chairman Mao’s revolutionary line and with a view to rationalizing the recovery of these metals, we have taken the pro-Lin Kong Kong as a driving force and conducted two major reforms to the original technological process. Originally, the zinc powder was replaced by two sections of zinc powder, and the consumption of zinc powder was as high as 180 (kg / ton of soot). Although zinc can be recovered as zinc sulfate, the source of zinc powder is more difficult. To this end, after the switch to hydrolysis enrichment - P204 extraction process, through the production practice, the process is still not ideal, the enrichment multiple of the value of the metal is not high; In addition, the first step in the process
