The European standard EN 13274-8 provides a test method for the determination of dolomite dust occlusion for respiratory protective devices. In our country, this standard was published by the Turkish Standards Institute (TSE) under the following name: TS EN 13274-8 Respiratory protective equipment - Test methods - Part 8: Test for dolomite dust suppression. Dolomite is a type of limestone. Dolomite, rich in magnesium and calcium carbonates, also contains minor minerals. It is used in the chemical industry in acid neutralization, stream restoration projects, and as a soil conditioner. Two schemes for the production of magnesium chloride are briefly described below. The choice of one or another scheme depends on the availability of cheap hydrochloric acid or ammonia nearby.
