Lithium extraction technology market Lithium is extracted from pegmatite, continental brine, geothermal brine, oil field brine and hectorite clay minerals. The extraction method adopts two forms: drilling and blasting room-pillar mining in the open-pit mine and extraction in the salt lake. Although lithium ore such as spodumene, lepidolite, and lapholite are directly consumed by glass and ceramic companies, they also need (1700-2000ppm) salt lakes or salt fields to produce lithium compounds, which are needed in the production of lubricants and glass The main source of lithium compounds or lithium carbonate. Lithium extraction methods mainly include sulfuric acid method extracted from ore and lime method extracted from brine. The recent reduction in the cost of extraction from brine has led to a reduction in the production of lithium ore. In order to improve the competitiveness of lithium ore, the refining process is being continuously improved. For example, from granite pegmatite, high-quality quartz and feldspar that meet the needs of lithium commercial use are extracted. Recently, we are focusing on the extraction of useful metals from seawater. Lithium Resource Market According to the research of the United States Geological Survey, the world's available sources of lithium burial amounted to 11 million tons, of which the buried amount of commercial development value reached about 4.1 million tons. In 2008, the production volume of lithium was 27,400 tons, which were 12,000 tons in Chile, 6,900 tons in Australia, 3,200 tons in Argentina, and 3,500 tons in China. Lithium application products market Due to the electrochemical reaction of lithium and other unique properties, various commercial products using lithium such as LiH, LiOH, LiBr, LiF, LiI, and Li2MoO4 have emerged. If you look at the main uses of lithium products, lithium carbonate (Li2CO3) is used for heat-resistant porcelain, glass additives, secondary batteries, and continuous casting of steel; lithium hydroxide (LiOH․H2O) is used for heat and pressure resistance, grease and batteries ; Lithium odorate (LiBr) is used as refrigerant absorbent; Lithium salt (LiCl) is used in electric welding rods, fluxes, and lithium metal raw materials; metal lithium is used in catalysts, batteries, alloys, pharmaceuticals, etc. Recently, the scale of secondary batteries used in portable devices (mobile phones, PDAs, notebooks, etc.) has also continued to grow by about 10%. But if you look at other lithium consumption, the scale has grown from 5,000 tons in 2010 to about 12,000 tons in 2020. The alloy field, which has a growth rate of more than twice, has developed into a hot field, while other industrial fields have an annual growth rate of 5 % Continues to develop. u003c/pu003e
