Sulfidization flotation performance of malachite in the ...

2019-3-1  Micro-flotation tests were performed in order to investigate the flotation performance of malachite and calcite. Fig. 1 shows the flotation recovery of two minerals in the absence and presence of sodium sulphide when SBX was used as collector. As shown in Fig. 1, in the absence of Na 2 S, the floatability of malachite and calcite using the SBX collector is weak.

Efficiently separating malachite from talc using new ...

In single mineral flotation test, 40 mL of deionized water and 2.0 g of malachite or talc samples were placed in the flotation cell. Then, NaOH or HCl solution was used to adjust the pH to an expected value, after which the desired amount of famciclovir was added and allowed to react for 3 min, and then 2# oil was added and allowed to react for ...

Influence of Bacterial Detachment on the Bioflotation of ...

The effects of the bacterial growth phase on the malachite flotation were investigated in a well-controlled Hallimond tube system. Rhodococcus opacus, which is one of representative hydrophobic bacteria, was employed for this study. The test results showed that the bacteria in the stationary phase exhibit two-fold greater floatability than those in mid-exponential phase.

In this study, the flotation behavior of malachite was investigated using hydrophobic talc nanoparticles (TNs) as collectors. To improve the floatability of TN-deposited malachite, various experimental parameters were systematically investigated. We found that the floatability sharply increased as the size of the TNs decreased. The floatability of malachite was enhanced in the presence of ...
