The continuously increasing demand for lithium has made it one of the strategic metals, rendering its exploitation of critical importance. Natural α-spodumene is still the primary resource of lithium extraction. The traditional process for the treatment of α-spodumene generates immense quantities of waste residue and needs a high-temperature heat treatment, leading to high energy consumption.

The Company is also involved in the development and commercialization of a new process to extract lithium from spodumene concentrate through its Global Lithium Extraction Technologies joint venture.

The most common process of extracting lithium from spodumene is the sulfuric acid roasting process. In this process, spodumene is roasted with sulfuric acid at 250 °C followed by leaching with water to extract lithium in the solution. However, this process is preceded by a calcination step at a temperature of over 1000 °C to transform α ...

Through the joint venture agreement governing the JV, the Company is also engaged in the development and commercialization of a new process to extract lithium from spodumene …

Chlorination roasting was used to extract lithium as lithium chloride from β-spodumene. The roasting was carried out in a fixed bed reactor using calcium chloride as chlorinating agent.

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. Lithium is a metal commonly used in batteries ...

An improved sorbent could extract lithium from brines released by geothermal power plants, like this one near the Salton Sea. ... The element is also extracted from the mineral spodumene…

The ion-exchange based mechanism is similar to that previously reported for methods using sulfuric acid (Xiao et al., 1997) and calcium chloride roasting (Barbosa et al., 2015) to extract lithium from β-spodumene, where Li + was replaced by H + and Ca 2+, respectively. However, this extraction process was built on strong base transforming to ...

The primary lithium-bearing mineral in this ore is usually spodumene, and therefore most of these mines produce spodumene concentrate as the final product. The spodumene concentrate is then usually sold and shipped to lithium hydroxide or carbonate conversion plants, mostly located in Asia, where it is converted to these respective lithium ...
