2019-1-2 Among the three approaches, the dolomite flotation process gives the lowest MgO content in the final concentrate, but it comes with low recovery and high costs. Unless it is absolutely necessary to achieve a concentrate with 0.7% or less MgO, the dolomite flotation is not recommended.

2004-7-1 The mixed depressant had no effect on the flotation of calcite, but it depressed dolomite flotation when its concentration was above 2 × 10 −4 M. Fig. 8 shows that the mixed depressant had little effect on the flotation of calcite and dolomite at 1 × 10 −4 M across the pH range tested. However, the mixed depressant caused strong depression of both pyrite and chalcopyrite between pH 9 and 10.5.

2021-2-1 Therefore, it is of importance to seek efficient methods to recover apatite from dolomite. Flotation, a separation and concentrate process that utilizes the different physicochemical properties of minerals to remove gangue minerals from valuable minerals , , , , is regarded as the most effective method for removing dolomite from apatite , , .

2020-10-15 The micro-flotation of dolomite and magnesite was carried out in a laboratory flotation device (mechanical agitation) with a 30-mL detachable cell and a stirring speed of 1992 rpm. The flotation slurry was prepared by adding a single mineral (2 g) or artificially mixed minerals (1.2 g magnesite and 0.8 g dolomite) into 25-mL DI water in the flotation cell.

2018-6-10 The concentrate is leached by acetic acid for the selective dissolution of dolomite. The acetic acid concentration of 0.31 M, the temperature of 80.33 °C, time of 126.29 min are chosen as optimum operational conditions using central composite design (CCD). It was found out the liquid to solid ratio of 4:1 is suitable for leaching purpose.

dolomite flotation concentrate. To all who contributed and guided me in the accomplishment . 10. The concentrate is reconditioned (30 seconds) with sulfuric acid (maintains pH 4-5). This is followed by flotation to remove dolomite. Final processing involves cationic flotation of the fine silica from the dewatered dolomite flotation cell.

1996-8-1 The results of bench-scale testing of five flotation processes for the separation of dolomite from phosphate are discussed. Each process is compared in terms of phosphate recovery, MgO content of the concentrate and reagent consumption. Water quality was found to play a major role in the performance of these processes. The effect of water hardness, in addition to other parameters, are

These experiments also indicated that conventional froth flotation would not be expected to provide adequate dolomite removal using these reagents. Cost estimation calculations are included that indicate that a jig process is approximately 1/20 th the cost of a comparable-capacity heavy-media process for removing dolomite.
