β-spodumene. The α-spodumene is virtually refractory to hot acids. As a result of the phase transformation, the spodumene crystal structure expands by about 30% and becomes amenable to hot sulphuric acid attack. Due to this expansion, the specific gravity of the spodumene decreases from 3.1 g/cm3 (natural α-spodumene) to around 2.4 g/

Abstract. Email to a Friend. "Spodumene mineral is a source of lithium for lithium ion batteries. Thus, the production of a spodumene concentrate with an approximate grade of 6% Li2O is targeted. Traditionally, spodumene is concentrated by froth flotation using fatty acid as the collector. Amine collector can also be used to float mica ahead of ...
Combined beneficiation method refers to the use of non-single separation methods for joint operation in order to obtain high-quality spodumene concentrate, low-iron spodumene concentrate or ...
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. It was also observed that upon the addition of …

The chemical beneficiation is used in brine process plant. At present, the main lithium minerals exploited are lepidolite, spodumene, montebrasite, petalite, salt lake brine, etc. The main beneficia tion method of lepidolite is flotation and the main beneficiation method of petalite is heavy medium separation.
Beneficiation of spodumene typically includes heavy media separation, magnetic separation, and flotation followed by pyrometallurgical and hydrometallurgical processes to extract the Li (i.e., LiCO 3) (e.g., [6, 23] and references therein). The results from the HLS indicate that a large mass of the gangue minerals could be rejected to the ...
Broadly, to create spodumene concentrate, the mined spodumene-bearing ore is crushed and ground, then subjected to beneficiation to separate the spodumene from other minerals and impurities. The spodumene concentrate is then roasted to remove any remaining impurities. Specific steps and conditions can vary based on ore deposit …
There are three well-known methods for roasting spodumene. The first is acid roasting, which involves baking the calcined spodumene product with an excess of concentrated sulphuric acid at a temperature of about 250 °C (for conventional heat treatment) or 320 °C (for microwave irradiation for 20 s) [ 19].
To that end, feasibility studies for a 4,5 million-tonne per annum beneficiation plant were underway. "For the beneficiation plant, it has got two phases. Phase one of it is the dense medium separation. We have budgeted about US$50 million for that," Gambiza said. "Phase two of the beneficiation plant is the floatation plant itself.
