The 5 Most Useful Methods Of Lithium Mining Beneficiation JXSC

Chile, China, and Argentina all have rich reserves of lithium, but they are all eclipsed by the Salar de Uyuni in Bolivia, South America. According to the US Geological Survey, the lithium reserves under the Uyuni salt marsh are staggering, accounting for almost half of the worlds lithium. If the lithium mine resources are fully developed, Bolivia, a poor South American country, will rival the Middle East giant Saudi Arabia.

From the perspective of the changes in the various uses of lithium in recent years, the battery has become the first largest application field in terms of the growth rate of lithium in other fields. At present, the global demand for lithium carbonate is around 140,000 tons. It is expected that the global demand for lithium carbonate will maintain an average annual growth rate of 15% to 20%, driven by the growth in demand for global consumer electronics and new energy vehicles. The annual consumption will reach more than 300,000 tons, and the proportion of new energy vehicles to lithium carbonate will increase from 9.7% in 2012 to 37.8% in 2018. If the global new energy vehicles, especially the pure electric vehicles represented by the US Tesla, grow faster, the global demand for lithium carbonate will reach 350,000 tons by 2010. As for the supply of lithium carbonate, there will be a gap in the supply and demand of global lithium carbonate by 2019.

Hand selection method

The hand selection method is a sorting method based on the difference in color and appearance between lithium minerals and gangue minerals. The selective particle size is generally 10 to 25 mm, and the determination of the lower limit of the particle size depends on economic benefits. Hand selection is the earliest method of mineral processing used in the history of lithium mine production. In addition to spodumene, the hand selection is also used to pick lithium concentrates from lithionite,...

Flotation method

In the 1930s, flotation was applied to the industrial production of spodumene concentrate. There are two flotation processes of spodumene: one is positive flotation and the other is reverse flotation. 1 The positive flotation that is preferential flotation of spodumene, the working principle: ground fine ore in an alkaline medium formed by sodium hydroxide or sodium carbonate, after high concentration, strong agitation and multiple washing and de sludge, the fatty acid or its soap is added as...

Thermal cracking beneficiation method

Working principle When the natural spodumene is about 1100 °C, its crystals change from α type to β type, and at the same time, the volume expands and easily breaks into powder. Through grinding and screening producers, can achieve separation of spodumene and gangue minerals.
