fect on reverse flotation of hematite, are neglected in previ-ous works. Therefore, it is necessary to investigate the ef-fects of siderite on the floatability. In this work, the effects of siderite on reverse flotation of hematite were investigated by micro flotation, adsorption tests, and Fourier transform infrared spectroscopy (FTIR).

By common knowledge, DDA is a cationic collector which is often applied for the reverse flotation separation of hematite from quartz [26], [27]. Hematite and quartz flotation properties were investigated in the presence of XG and DDA (50 mg/L), as shown in Fig. 2. The tests were conducted at nature pH 6.3 in Fig. 2 (a). The quartz recovery …

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 ...

1. Introduction. Reverse flotation is one of the most commonly used industrial beneficiation methods of hematite ores [1].During this process, hematite is left as the non-floated fraction, whereas silicates rise upward into the floated froth layer with the aid of attached air bubbles [2].In reverse cationic flotation, modified starch, dextrin, and …
