Simultaneous flotation separation of quartz and dolomite

Few literatures pay emphasis on investigating the use of anionic and cationic’s combined collector in flotation separation. In this work, we evaluated the effectiveness of a new combined collector for the separation of collophanite, dolomite, and quartz using isooctyl ether phosphate (AEP) and octadecylamine polyoxyethylene ether (AC1810).

Flotation Separation of Apatite From Dolomite Using

Suitable separation of apatite from dolomite was achieved with dodecylamine hydrochloride in the presence of sodium chloride. Zeta potential measurements revealed that sodium chloride acts as an indifferent electrolyte for dolomite, but causes a shift in the iso-electric point of apatite.
