talc flotation chemistry

Talc is widely used, and pure talc ore is rare, usually accompanied by other minerals, such as chlorite, magnesite, tremolite, dolomite, siderite, quartz, pyrite, etc these minerals change the chemical composition of the ore and significantly affect the physical properties of talc in order to improve the quality and meet the needs of industrial production,
