在无机盐工业生产中,不少产品是通过粉碎后的矿物粒子与酸、碱作用而制得的。例如:钛铁矿与硫酸作用生成硫酸钛,通过一系列工艺处理制得二氧化钛;焙烧脱硫后的锌精矿与硫酸作用生成硫酸锌,再经一系列净化处理,与硫化钡作用,制得锌钡白;软锰矿与氢氧化钾及空气中的氧作用,生成锰酸钾,再经电解(或碳化)制得高锰酸钾,铬铁矿与碳酸钠、白云石等作用制得铬酸钠等等,不胜枚举。
In inorganic salt industrial production, many products are made by crushing the mineral particles with acid and alkali. For example: ilmenite and sulfuric acid to produce titanium sulfate, through a series of processes to obtain titanium dioxide; Roasting zinc concentrate and sulfuric acid to produce zinc sulfate, and then after a series of purification treatment, and barium sulfide effect, zinc Barium; Pyrolusite and potassium hydroxide and oxygen in the air to produce potassium permanganate, and then by electrolysis (or carbonization) obtained potassium permanganate, chromite and sodium carbonate, dolomite and the role of chromic acid obtained Sodium and many more.
