−− In this paper, we present the results and a discussion of microflotation tests performed with manganese minerals (rhodonite and rhodochrosite) and quartz mineral, using sodium oleate as the collector. We also explore the influence of water glass (sodium silicate) as a depressant in the recovery of these minerals with sodium oleate. Potential zeta determinations were carried out …

The flotation tests were performed in a 40 mL FGC-type hanging tank flotation machine at an impeller speed of 1630 r/min. First, 2.0 g of the mineral sample was weighed into the 40 mL flotation tank, 36 mL of deionized water was added, and the pulp was stirred for 1 min to ensure it was as uniform as possible.

When compared to pure kaolinite flotation, the kaolinite recovery after 6 min of flotation showed an increase from 51% (pure kaolinite flotation) to 57% (kaolinite flotation in the hematite–kaolinite mixture), as shown in Fig. 19. However, although the total collector dosage was the same in both tests, the specific dosage of the collector (g ...

Compared to iron, the impact of manganese in sphalerite flotation is less understood. Flotation tests conducted by Greet et al. (2000) showed better recovery for sphalerite with higher manganese content. On the other hand, a study by Schouwstra et al. (2010) showed lower recovery for manganese-rich sphalerite ore. The results showed that the ...
