SF-323, isopropyl ethyl thionocarbamate is a powerful collector, yet more selective than the xanthates. This product is used in the flotation process for copper sulphides in alkaline or neutral circuits. Its selectivity makes it suitable for the flotation of copper sulphide in the presence of pyrite at ranges of pH between 10 and 11.5.

scheelite uses ellul

Scheelite (CaWO 4) is a typical tungstate mineral and usually co-exists with other calcium-containing minerals, such as calcite (CaCO 3) and fluorite (CaF 2) in deposit.By now, flotation is the most commonly used technique to separate scheelite from calcite and fluorite.
