The invention discloses a method for extracting lithium salt from spodumene by a soda ash pressure leach method. The method comprises the following technological process: (1) roasting and transforming; (2) cooling and grinding; (3) size mixing; (4) pressure leaching; and (5) cooling and decompressing. The method is characterized by further comprising the following technological process: (6
#0183;#32;The extraction of lithium by means of the chlorination roasting of spodumene has been studied in the temperature range from 1000 to 1100 #176;C for periods of time from 0 to 180 min. The roasting was carried out in a fixed bed reactor using pure gaseous Cl 2 as chlorinating agent.
Lithium Extraction from Spodumene Ore TechnoEconomic Assessment with SuperPro Designer April 2020 Project: Simulation of Metal Extraction and Recycling Processes
Hard rock / spodumene lithium extraction While accounting for a relatively small share of the worlds lithium production, mineral ore deposits yield nearly 20 tons of lithium annually. Well over 100 different minerals contain some amount of lithium, however, only five are actively mined for lithium production.
Lithium mining carries high environmental costs. Mining companies prospecting lithium in northern Tibet, salt plains of South America, and Chile as well as lithium at Bolivia''s Salar De Uyuni require extensive extraction operations and water in a dry land.
EFFECT: increasing of lithium extraction from concentrate of spodumene into lithium carbonate and volume reduction of solid wastes during receiving of lithium carbonate from the concentrate of spodumene. 1 tbl, 1 ex
Among these three modifications spodumene proven suitable for lithium extraction processes, hence the production of these phases should be closely monitored in feed preparation stage. In order to extract lithium from spodumene, form of the mineral goes through acid roasting with concentrated sulfuric acid at
Commercial Lithium Production and Mining of Lithium
#0183;#32;Lithium Australias LieNA technology enables the production of lithium concentrate from fine spodumene material that is often discharged as waste during traditional concentration processes.
#0183;#32;According to Chen et al. (2011), the process of extracting lithium from spodumene included two steps after decrepitation. In the first step, lithium was extracted as lithium carbonate in solid phase. Then, the solid phase went through the carbonation process and converted to soluble carbonate.
#0183;#32;Most lithium is commercially produced from either the extraction of lithiumcontaining salts from underground brine reservoirs or the mining of lithiumcontaining rock, such as spodumene. Lithium production from clay sources is expected to become commercially viable, though perhaps not until 2022.
The recovery of lithium from spodumene (6#183;9% Li 2 O) by bioleaching was investigated. This process was carried out using heterotrophic microorganisms previously isolated from the mineral. Penicillium purpurogenum, Aspergillus niger and Rhodotorula rubra were assayed separately.

Lithium extraction from the solid obtained after roasting was also investigated. The results of thermodynamic analysis provided a better understanding of the alkaline process for lithium extraction. The metallurgical tests allowed 84% recovery of the lithium contained in the spodumene concentrate. 2
#0183;#32;The sulfuric acid process is the dominant technology for lithium extraction from spodumene. However, this process generates huge quantities of waste residue and needs hightemperature pretreatment.
LITHIUM EXTRACTION FROM SPODUMENE SGS Minerals Services has experience with complete flowsheet development to recover high grade lithium products from hard rock lithium minerals. SGS offers a multidisciplinary team that is involved from the initial stages of the
This form of lithium follows extraction from a pegmatite rock, which is popular for its high lithium content. Spodumene is a highly exploited lithium source and was the main source of the rare metal for a long time. Spodumene is a gemstone and its price fluctuates depending on the demand.
#0183;#32;The anticipated increase in demand for lithium salt brings a growing concern over lithium shortage and environmental problems in the industry of extracting lithium from ores.
