أكمل القراءةThe effect of pH on the flotation recovery of barite and calcite using SDS and NaOL as collectors was studied by micro-flotation tests, as shown in Fig. 3. It could be seen from Fig. 3 that the flotation recovery of barite with SDS increased in the pH range from 8.0 to 10.0, and at an optimum pH of approximately
أكمل القراءةIn barite flotation, the addition of metal cations can expand the pH range of mineral flotation and play an activating or inhibiting role. Aluminum sulfate is an effective inhibitor of barite. When the pH of the slurry is 4.5~7.5, aluminum sulfate has a strong inhibitory effect on barite, while fluorite can still maintain good floatability.

أكمل القراءةBarite deposit at Mangampet is one of the world's largest deposits containing around 61 million tonnes of recoverable barite. Beneficiation of low grade barite dumps interlocked with schist and slate gangue was studied using amine as collector (reverse flotation) to avoid the collector coating on barite. Instead of conventional flotation cells, flotation …
أكمل القراءةThe flotation performance of 37–74 µm fluorite and different size fractions of barite (−10, 10–37, 37–74 µm) were conducted as a pH function using 1×10 −4 mol/L of collector NaOl and the results of which are presented in Fig. 1.As is shown, the flotation recoveries of fluorite were very high (~90%) across the entire studied pH range in the presence of NaOl.
