Hebei Messi Biology Co., Ltd. stated that adding magnesium oxide to microcrystalline glass can adjust the crystallization temperature of glass. At low temperatures, it can alleviate the decrease in glass viscosity, and at high temperatures, it can accelerate the increase in viscosity. Excessive iron and chloride in magnesium oxide will affect the color of glass. […]

Hebei Messi Biology Co., Ltd.. stated that cobalt, nickel and magnesium often coexist in the sulfuric acid leaching solution of nickel oxide ore. The saponification P507 process is usually used to separate cobalt and nickel. This process has problems such as the introduction of impurity ions, long process flow and wastewater discharge. The magnesium oxide

Hebei Messi Biology Co., Ltd. stated that after simple purification of brine, lime as a precipitant is added to produce magnesium hydroxide precipitation. The slurry produced by the reaction must be concentrated by precipitation and filtration to wash away excess chloride to make slurry with various solid contents. When preparing the slurry, the stability of
