Enonkoski ore ground in a steel mill Soated easily without a collector at low pH values of 3}5 (Figure 1). The Soatability of these three minerals was improved when the same ore was ground in aceramic mill (Figure 2).Thissuggeststhatcollector-less Sotation in acidic pH can be adopted as a low-cost pre-concentration phase to obtain a bulk sulRde

Reverse flotation of iron ore is now drawing more attention in iron ore industry as an efficient beneficiation process (Ma et al., 2011, Filippov et al., 2010, Araujo et al., 2005, Houot, 1983). In reverse cationic flotation, silica and silicates are floated after depressing the iron oxide by suitable reagents such as starch, dextrin, and CMC.

Different reagents with collecting activity were studied in the IOA ore tailings flotation experiments. For Sample A, the optimum dosage of the collectors to be used was first determined by conducting stepwise rougher flotation. The collector was added as follows: 100 g/t, 50 g/t, 50 g/t, 50 g/t, and grade-recovery curves are shown.

Cao Z., Zhang Y., and Cao Y. studied the reverse flotation of quartz in magnetite with modified sodium oleate . The purpose of this study is to study the purification effect of the DDA/NaOL/SDS mixed collector system for low-grade quartz ore. By studying the number of mixed collectors used, the flotation effect of quartz sand is optimized.
