With the surge in global demand for lithium batteries (especially in electric vehicles and renewable energy storage), the importance of lithium resources is becoming increasingly apparent. However, lithium ore is typically low-grade and must undergo beneficiation to extract usable lithium concentrate. This article will introduce the distribution and development<\/strong> of lithium mines and analyze in detail five of the most commonly used lithium ore beneficiation methods<\/strong>, including hand sorting, flotation, thermal cracking, heavy media separation, and magnetic separation.<\/p>\n

Lithium Introduction: Distribution & Development Prospects<\/h2>\n

Lithium is an important strategic resource widely used in emerging fields such as batteries, ceramics, glass, aluminum, lubricants, refrigerants, the nuclear industry, and optoelectronics. It is an indispensable and important raw material for modern high-tech products.

Distribution of Lithium Ore<\/h3>\n

Chile, China, and Argentina all have rich lithium reserves, but the Salar de Uyuni in Bolivia, South America, eclipses them. According to the US Geological Survey, the lithium reserves under the Uyuni salt marsh are staggering, accounting for almost half of the world’s lithium. If the lithium mine resources are fully developed, Bolivia, a poor South American country, will rival the Middle East giant Saudi Arabia.<\/p>\n

Lithium Development Prospects<\/h3>\n

From the perspective of the changes in the various uses of lithium in recent years, the battery has become the 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.

En cuanto a la oferta de carbonato de litio, en 2019 habr\u00e1 un desfase entre la oferta y la demanda mundiales de carbonato de litio.<\/p>\n

5 Most Useful Lithium Ore Beneficiation Methods<\/h2>\n

1. Hand Sorting: The Original Technique<\/h3>\n

Hand sorting is a separation method based on the difference in color and appearance<\/strong> between lithium minerals and gangue minerals. The selective particle size is generally 10 to 25 mm<\/strong>, and the determination of the lower limit of the particle size depends on economic benefits. Hand sorting method is the earliest method<\/strong> de tratamiento de minerales<\/a> used in the history of lithium mine production. In addition to spodumene, the hand selection is also used to pick lithium concentrates from lithionite, petalite, and amblygonite.<\/p>\n

El m\u00e9todo de selecci\u00f3n manual ha sido generalmente sustituido por la flotaci\u00f3n u otros m\u00e9todos debido a su alta intensidad de mano de obra, baja eficiencia de producci\u00f3n y gran desperdicio de recursos.<\/p>\n

2. Flotation: The Dominant Industrial Method<\/h3>\n

In the 1930s, flotation was applied to the industrial production of spodumene concentrate. There are two flotation processes of spodumene<\/a>: one is positive flotation<\/strong>, and the other is reverse flotation<\/strong>.<\/p>\n
