Flotation of quartz from quartzfeldspar mixtures by the Quartz can be floated from feldspar in diluted HF solutions simply by the aid of frothers • There is a high flotation separation selectivity between quartz and different types of feldspar • A feldspar concentrate of 99 9% at a recovery of 95% was produced • The results could be In 1939 the United States Homola (O Meara) proposed by HF as activating agent fatty amine as collector of feldspar flotation method agent although the law is a good separation effect and has been widely used in industrial production in a long period of time but because HF belongs to toxic agents to live easily polluted water Gong and
