· Extracting lithium from ores has higher operating costs than conventional extraction from brine, however, the theory of supply and demand makes the processing economically prudent because of the increasing price of lithium. Spodumene is the main ore of interest due to its high lithium content (~8 wt.% as Li 2 O in a pure mineral specimen) .
Additionally leaching pulp is neutralised up to pH 6.0-6.5 by solution of lithium hydroxide from the caustification stage. EFFECT: increasing of lithium extraction from concentrate of β-spodumene into lithium carbonate and volume reduction of solid wastes during receiving of lithium carbonate from the concentrate of β-spodumene. 1 tbl, 1 ex
· The measured and indicated resource of 6.4 Mt LCE is capable of sustaining current continuous production for 40-plus years with only ~15% of the defined resource extracted. Location. The Olaroz Lithium Facility is located in Jujuy Province in northern Argentina, approximately 230 kilometres northwest of the capital city of Jujuy.
· The lithium extraction efficiency of 91.6% could be achieved at a mass ratio of lepidolite/Na 2 SO 4 /K 2 SO 4 /CaO of 1:0.5:0.1:0.1 and roasting at 850 °C . Roasting at 880 °C with a mass ratio of lepidolite/Na 2 SO 4 /CaCl 2 of 1:0.5:0.3 resulted in improved recovery (~ 95% Li) of lithium (Yan et al., 2012b).
· Earlier work by Crocker et al. (1987) from the US Bureau of Mines showed that > 85% lithium could be recovered from montmorillonite-type clays from Nevada (containing 0.3–0.6% Li) by different processes based on roasting the ore with KCl–CaSO 4 or CaCO 3 –CaSO 4, followed by water leaching and precipitation of 99% pure lithium carbonate ...
· However, recycling could be worthwhile. Consider that in 2015, lithium-ion batteries consumed metals and minerals worth $2 billion. The price of cobalt rose by more than 80% over the past twelve months, and cobalt demand is estimated to double by 2020, to 200,000 tons per year. Demand for lithium is expected to quadruple by 2025, to 780,000 tons.
Primary sources of lithium are ores and brine deposits (Ziemann et al., 2012). The second one, being easily available and with substantial lower operating costs, have replaced the ore extraction in the last decades. Nowadays, most of the lithium commodities in the market are coming from the exploitation of brines, mainly in South America.

Fersman), which includes the following, subtypes: spodumene pegmatites (the main type of lithium ore deposit), lepidolite-spodumene pegmatites (0.6–1.2 percent Li 2 O), and ...
of lithium continues to rise [5,6]. Various methods have been developed to obtain lithium from lithium ores [7−10]. Presently, the most important process for extraction of lithium from lithium alumino−silicates is the lime method [11]. However, it is well known that too many limestone and high energy are consumed.
· A Cost Comparison: Lithium Brine vs. Hard Rock Exploration. Lithium brine exploration infographic presented by: Dajin Resources Capital is limited in the current mining exploration environment, so investors are increasingly looking for companies that have lower costs of doing business.
However, the most abundant Li ore is lepidolite, a type of pegmatite, that has an ideal formula of K(Li,Al) 3 (SiAl) 4 O 10 (F,OH) 2, and its distribution is much wider than that of lithium brine.
· An Overview of Commercial Lithium Production. Most lithium is commercially produced from either the extraction of lithium-containing salts from underground brine reservoirs or the mining of lithium-containing rock, such as spodumene. Lithium production from clay sources is expected to become commercially viable, though perhaps not until 2022.
· The lime process is a fairly simple method, but it has several significant drawbacks: this method is applicable to lithium-rich concentrates, and lithium extraction for such concentrates does not exceed 70%, due to the limited solubility of lithium hydroxide (9.83% by mass at 0°C; 11.1% at 25°C; 11.52% at 50°C; 14.96% at 100°C) in water. 11
