Material, heated through direct contact with the shell, rolls along the drums interior, exposing fresh material as it tumbles to promote even heat distribution throughout the bed, sometimes with the help of bed disturbers. Lithium chemical processing capabilities are key to capturing higher margins for lithium producers. In order to reduce the energy consumption of the acid roast process application of microwave oven was proposed. BloombergNEF has forecast that global sales of EVs will grow from 1.1 million in 2017 to 11 million in 2025, with China accounting for nearly half of those sales in 2025. Most hard rock mining is associated with lithium-bearing spodumene in pegmatite deposits. Spodumene forms three different crystal structures, the naturally occurred - spodumene, and y and -spodumene which are the products of heat treatment at 700 to 1100 C. However, its important to recognize that the term is widely used to describe all manner of thermal processes. Among these minerals, spodumene (LiAlSi 2 O 6) has attracted the most interest due to its high lithium content (8.03% Li 2 O) and comparatively lower process cost, and has been commercially mined for lithium extraction since the middle of the twentieth century (Choubey et al., 2016, Ellestad and Leute, 1950, Rosales et al., 2019). Through calcination, both decrepitation and acid roasting can be achieved in the effort to produce lithium carbonate and lithium hydroxide for use in lithium-ion batteries or other applications. The kiln is set at a slight angle in order to allow gravity to assist in moving material through the rotating drum. Conversion of to -spodumene is accompanied by shrinkage of the crystal units leading to contraction of particles.

Dried lithium concentrate is then processed in a rotary kiln (calciner) to convert the spodumene from alpha to beta phase, in order to make it more amenable to reaction. Owner 92 Resources recently joined forces with Far Resources on the project. Since the -spodumene ore is not sensitive to products of combustion, a direct-fired rotary kiln is used to process the material in this setting. Metallurgical studies to date have yielded a high-value, low-impurity lithium carbonate product, not a concentrate, through commercially used processing routes. However, exploding demand for lithium is calling for more lithium-bearing resources than ever before. The highest extraction of 98% was achieved after roasting at 250 C for 1 hour with 80% excess acid to the stoichiometry of the reaction of spodumene and sulfuric acid. Then, our next-generation reverse osmosis (RO) system, XtremeRO, concentrates lithium chloride (LiCl) up to 50% higher than conventional RO.
