Timestone beneficiation by Column and Conventional

The run-of-mine limestone assaying 78.5% total carbonates and 20.9% acid insolubles was beneficiated using laboratory scale conventional and column flotation process for improving the grade and recovery by direct flotation technique. A limestone concentrate of 94.3% total carbonates and 4.7% acid insolubles with 79% weight recovery was obtained

Beneficiation of limestone plant rejects for value

Nov 15, 2013· Attempts have been made to recover the additional calcium values from the limestone plant rejects by flotation as a beneficiation technique. The characterization study indicates, quartz and calcite are the major minerals present in this sample, while concentrate is highly upgraded with calcite content, by rejecting mostly quartz and clays in the tailing.
