Effect of Ca selective chelator BAPTA as depressant on flotation separation of magnesite from dolomite

With the depletion of high-grade magnesite mineral resources, improving the grade of magnesite obtained from gangue minerals such as dolomite has been attracting considerable attention from the industry. However, it is difficult to achieve the effective separation of magnesite from dolomite because of their similar chemical and crystal properties. In this study, 1, 2-bis (o-aminophenoxy) ethane-N,N,N′,N′-tetraacetic acid (BAPTA) was used as a...
