  • (PDF) Optimisation of spodumene flotation

    In reverse flotation, gangue minerals are floated with cationic collectors to produce spodumene concentrate (as tailings) whereas in direct flotation, spodumene is floated with anionic collectors...

  • Improving spodumene flotation using a mixed cationic and

    Spodumene flotation is an important and challenging step for lithium extraction and production from lithium ore. In the present work, flotation tests for three pure minerals (i.e., spodumene, quartz and feldspar) and a real spodumene ore were carried out at laboratory scale.

  • Minerals Free Full-Text Spodumene Flotation Mechanism

    Fine and coarse fractions of spodumene were obtained from a pegmatite ore and their flotation was investigated under different conditions. In particular, the optimum pH and collector dosage were studied. It was found that the best flotation performance occurs at pH 10 using 250 mg/L of sodium oleate.

  • A novel approach for flotation recovery of spodumene,

    10-02-2018· The second grinding process is added between the roughing flotation and cleaning flotation of spodumene, in which the tailings of spodumene roughing flotation is further ground to 65% passing 74 μm. Fig. 5 shows the flowsheet for comprehensive utilization of lithium tailings recycling feldspar.

  • 1. Processing Spodumene By Froth Flotation For Lithium

    Processing Spodumene by Froth Flotation for Lithium Extraction Previous Spodumene theoretically contains 8.03% Li2O and therefore the production of this mineral is greatly increasing because of the expanded use of lithium in the manufacture of high temperature insoluble lubricants, ceramics, pyrotechnics, non-ferrous welding uxes, air purifying agents, and hydrogen isotopes.

  • A novel approach for flotation recovery of spodumene,

    10-02-2018· In the flowsheet, the tailings of spodumene flotation are treated by weak magnetic (160 kA/m) separation and high gradient magnetic (800 kA/m) separation to remove iron oxide. After magnetic separation, 450 g/t of mixed collector MSD and 3000 g/t of regulator H 2 SO 4 are added to the pulp slurry for feldspar roughing flotation.

    Spodumene exists generally in granite pegmatite deposits, which contain quartz, feldspar, muscovite as well as some tantalite and niobite. Flotation is the most important process to selective separate spodumene from other aluminosilicates (Jie et al., 2014). Since many investigations on flotation of spodumene have been conducted

  • An Overview of Spodumene Beneficiation OneMine

    DMS middlings and -0.5 mm fines can be processed by flotation to further recover spodumene. In the flotation process, coarse stage grinding minimizes the grinding cost and formation of slimes. In the majority of cases, a grind size (K80) of approximately 200 microns is sufficient for flotation. After primary grinding, mica, if present in an
