摘要
火试金法测定铜精矿中金银的含量,通常采用工业级二氧化硅作为酸性熔剂之一来使用。本文探索问题为将试剂玻璃瓶破碎、研磨至100目来代替二氧化硅使用,随着近年来环境保护意识的提升,将本来属于固体废物的化学试剂玻璃包装物资源化进行运用,有效减少了固体废物的产生量,同时进一步降低了生产成本。
While determining the content of gold and silver in copper concentrate with fire assay method,we usually use industrial-grade silica as one of the acidic fluxes.This article explores the problem of breaking and grinding reagent glass bottles to 100 mesh instead of silica.With the increase in environmental protection awareness in recent years,the use of chemical reagent glass packaging materials that are originally solid waste has been effectively reduced.The amount of solid waste generated,while further reducing production costs.
