Laboratory Flotation Testing An Essential Tool for Ore

A faster floating copper porphyry flotation test, however, may finish in five minutes and a first concentrate may need to be collected after 20 seconds. Depending on one’s circumstances, some deviation may be required from the recommended test conditions (eg use of high

New insights into the mechanism of selective flotation of

The flotation separation test for copper and solder focuses on the effect of different pH values and on the amounts of collector (ammonium dibutyl dithiophosphate, ADD) and frother (No. 2 oil). Furthermore, the XFD flotation machine with volume of 0.5 L is used for scale-up and verification test under optimized conditions, and 100 g samples
