The Flotation of Pyrite using Xanthate Collectors

The flotation properties of pyrite were found to be significantly influenced by va~iations in the pH In acidic solutions the pyrite floatability is very high, and recoveries of 95% could be achieved using only a frother A sharp decrease in floatability was observed in alkaline solutions, possibly due to the formation of hydrophilic ferric hydroxide The addition of a xanthate collector10/01/2015· Reverse flotation involves the flotation of ash forming minerals which means that the collectors used should be such that they make the mineral matter hydrophobic in nature Some of the most common minerals found in coal are quartz, clay minerals (like kaolinite, illite etc), feldspar, carbonates such as calcite, siderite and dolomite, and sulphide minerals such as pyrite Other lessAn overview of reverse flotation process for coal
