    Therefore, flotation tests at pH 85 were performed on the apatite and calcite mixtures (mass ratio equals 1:1) with and without the addition of PBTCA The test results were shown in Table 1 It can be seen from Table 1 that in the absence of PBTCA, P 2 O 5 content in the concentrate was almost the same as that in the original mixture, indicating selective separation was not achieved

  • Selective flotation of scheelite and calcite - [email protected]

    flotation tests to recover scheelite from tailings failed due to the dilution of the concentrate by calcite Hence to adopt the flotation process successfully, it is necessary to depress the calcite selectively which is not achieved easily(2) due to the presence of small amounts of Ca, Mg and Fe salts and the lean grade of the ores to be treated Slime coating(3) is also another factor
