高温氧化焙烧是直接法氧化锌生产的第一道工序,主要目的是使硫化锌氧化成氧化锌,同时尽可能地除去硫、铅、镉、砷等杂质,获得合格焙砂,其特点是高温低空气率的沸腾氧化焙烧。在某厂技术改造设计中采用该方法,取得了良好的社会效益和经济效益。 High temperature oxidation roasting is the first process of direct zinc oxide production. The main purpose is to oxidize zinc sulfide into zinc oxide while removing impurities such as sulfur, lead, cadmium and arsenic as much as possible to obtain qualified calcine, which is characterized by high temperature Low air rate boiling oxidation roasting. In a factory technical transformation of the design method, achieved good social and economic benefits.
