PROCESS DEVELOPMENT FOR EXTRACTING MAGNESIUM BINDERS FROM SHORSU DOLOMITE

Abstract

As a result of systematic studies on the thermal decomposition reactions of magnesium and calcium carbonates, magnesium hydroxide, and hydrosols, alongside the hydration of magnesium and calcium oxides, significant advancements have been made in the isolation of magnesium binders from Shorsu dolomite. The research further explored the precipitation of magnesium hydroxide with ammonia from solutions of magnesium nitrate and sulfate, and the interactions of magnesium oxide and hydroxide with various salt solutions, including the reaction of potassium chloride with sulfuric acid to form potassium hydrosulfate. These studies have laid the physical and chemical foundations for processing unconventional raw materials, such as dolomites and dolomitized magnesites, to produce pure oxide and other magnesium compounds. Consequently, this work has notably expanded the raw material base for magnesium compound production, addressing an important national economic challenge.
