AI Technical Summary
In existing magnesite flotation processes, it is difficult to effectively separate magnesite from calcium-bearing gangue minerals such as calcite and dolomite. Traditional descaling agents are harmful to water bodies and easily cause pipeline blockage. Furthermore, existing descaling agents have poor selectivity and are difficult to achieve efficient and low-viscosity decalcification.
p-Hydroxyphenylglycine is used as an inhibitor, and its functional groups are used to enhance the selective adsorption of calcium-containing gangue by chemical adsorption and hydrogen bonding with the surface of calcium-containing gangue. The separation of magnesite and calcium-containing gangue is achieved by froth flotation.
It achieves efficient separation of magnesite and calcium-bearing gangue, reduces the CaO content in magnesite, improves the quality of magnesite, and avoids water pollution and pipeline blockage problems caused by traditional inhibitors. It has excellent selectivity and low viscosity characteristics.
