Insoluble Slimes Flotation. Batch insoluble slimes flotation tests were conducted in a Fagergren laboratory flotation cell. In each test, 1 kg (2.2 lb) of ore was scrubbed for 5 min at a pulp density of 27% solids in a saturated brine at a 4.22-m/s (830-ft/min) peripheral impeller speed to disperse the insoluble slimes.

Sylvite & Halite Flotation – Salt Mineral Collectors The flotation of sylvite (KCl) and also some accessory minerals (e.g. kieserite, langbeinite) from crude potash salts are processes used to a large extent all over the world.
The chemistry of halite flotation waste of potash processing is the following: NaCl (87.78 mass fraction, %), followed by KCl, CaSO 4, MgCl 2, insoluble residue, H 2 O cryst., Br − [80]. Fine ...
The subsequent recovery of sylvite may be improved with the flotation of the halite. 1.3. Interfacial water structure. ... The experimental flotation procedure Test C is shown in Fig. 8. This series of experiments were designed to determine the effect that occurs when the fine (mainly NaCl) precipitates were removed from the system before …
The possibility of application of halite flotation for potash ore pre-benefication has been discussed. The results of the investigations enabled the cost of beneficiated carnallite production to be decreased and the area of halite flotation implementation to be extended. ... (LM) at low temperatures. The flotation test results …

The flotation of sylvite (KCl) and also some accessory minerals (e.g. kieserite, langbeinite) from crude potash salts are processes used to a large extent all over the world. These separations are made in brines which are in an approximate solubility equilibrium with the mineral phases of the crude potash salts and thus contain …
The results of the flotation test at 25 °C indicated that the Gemini surfactant BM exhibited better selectivity for carnallite and better collector ability against NaCl than the traditional LM. ... Investigations of alkylmorpholines-collectors for a new halite flotation process. Miner. Eng., 16 (2003), pp. 1161-1166. View PDF View article View ...
Batch flotation tests were conducted in an XFD 500 cm 3 laboratory flotation machine (Wuhan Prospecting Machinery Factory, China) at pH 6. The flowsheet of the flotation kinetic test based on the current flotation flowsheet in SLNP is shown in Fig. 2a. For each experiment, 200 g of sample and 514 g of saturated solution were filled into the ...
