Magnetohydrodynamic & magnetohydrostatic methods of mineral separation by U. Andres, 1976, Wiley edition, in English

This study gives a comparison of leaching efficiency for lithium extraction from spodumene mineral with hydrochloric acid, aqua regia, nitric acid, sulfuric acid, and a novel eutectic solvent. Operational conditions under investigation are solid–liquid ratio temperature, stirring speed, and particle size. The reagents and products are …

Spodumene, sourced from Australia provided by Jiangxi Ganfeng Lithium Co., Ltd. in China, was crushed, ground, and sieved to ∼200 mesh (below 0.074 mm). ... Extraction …

Spodumene flotation stands as the most commonly used method to concentrate lithium minerals. However, it faces significant challenges related to low collector recoveries and similarity in the …

A three-dimensional magnetohydtostatic axial system comprises a magnetic field with its gradient set high vertically and low horizontally. The vertical gradient is used for levitation, with its axial rate of change monitored through the horizontal gradient. Useful fields are obtainable with pole faces generating a two-dimensional potential function …

Considering the cost of flotation, the optimum separation of spodumene and feldspar was determined to be a SA concentration of 30 mg/L, which yielded a feldspar recovery of less than 16% and spodumene recovery of more than 79%. These results indicate that a moderate amount of SA can effectively depress feldspar and has a …

The experimental results indicated the separation of spodumene from feldspar with a recovery of 88%, having an assay of 4.6% Li 2 O. Higher selectivity was attributed to the higher adsorption reaction heat difference of the mixed collector system as compared to the individual ones.

spodumene concentrates after roasting and acid roasting operations. A concentrate with at least 6% Li2O (approximately 75% spodumene) is suitable for roasting. Roasting is performed at about 1050°C, during which spodumene will go through a phase transformation from α-spodumene to β-spodumene. The α-spodumene is virtually …

With increasing battery demand comes a need for diversified Li sources beyond brines. Among all Li-bearing minerals, spodumene is most often used for its high Li content and natural abundance. However, …

Therefore, the flotation separation of spodumene from feldspar and quartz, may be achieved at a certain NaOH dosage. In order to examine the effect of NaOH on the flotation separation of spodumene from feldspar and quartz, the flotation of mixed minerals (spodumene:feldspar:quratz = 2:1:1, wt%) is carried out, and the results …

The experimental results indicated the separation of spodumene from feldspar with a recovery of 88%, having an assay of 4.6% Li 2 O. Higher selectivity was …

This is an article in the field of mineral processing engineering. The study objects are a spodumene waste rock in Sichuan. According to the mineral characteristics of thisspodumene waste rock, heavy medium separation tests were carried out at three different feed particle sizes (-15+0.5 mm, -10+0.5 mm, -5+0.5 mm) of the spodumene …

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 …

A three-dimensional magnetohydtostatic axial system comprises a magnetic field with its gradient set high vertically and low horizontally. The vertical gradient is used for levitation, with its axial rate of change monitored through the horizontal gradient. Useful fields are obtainable with pole faces generating a two-dimensional potential function multiplied by …

Due to its high lithium content, spodumene is considered the most important lithium ore mineral. Physically separating lithium minerals can be performed by wet and dry screening, tabling and magnetic, electromagnetic, electrostatic, magnetohydrostatic bullet, and heavy media separation.

These findings demonstrated that the mixed NaOL/ND13 showed a good selective flotation separation of spodumene and feldspar under optimal pH conditions. The following sections will provide additional evidence to reveal the role of NaOL/ND13 on the selective separation behaviors of spodumene and feldspar flotation. 3.3. Zeta …

Therefore, although Fe(III) effectively improved the flotation of spodumene, it was not beneficial for the flotation separation of spodumene from feldspar and quartz. …

In coming years, global lithium production is expected to increase as the result of widespread electric vehicle adoption. To meet the expected increase in …

Spodumene is one of the important lithium resources, so it is of great significance to concentrate it. Beneficiation methods of spodumene include magnetic …
