Study on Calcination Process of Serpentine Mixed with Ammonium Sulfate

摘要：

　　The research involves the calcination of QingHaiQiLian serpentine with ammonium sulfate in order to extract magnesium, and evaluates calcination results through the mass of water leaching residue that comes from the calcination, dissolution and filtration process.Optimal calcination parameters of serpentine and ammonium sulfate determined by orthogonal experiments, single-factor experiments, elemental analysis and SEM analysis are: calcination duration of lh, calcination temperature of 700℃, ammonium sulfate dosage of 90g (or mass ratio of ammonium sulfate to serpentine sample (m 1/m2) of 3∶2), under which condition a magnesium extraction rate of 62.75% can be achieved.
