In this study, a green extraction process of low-grade lithium claystone treated by chlorination roasting-water leaching was proposed. The mechanism of lithium conversion under chlorination conditions was also investigated to reveal the fugitive form of lithium in claystone and its migration behavior during the extraction process.

Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits. These strategies, without a doubt, harm the environment. Furthermore, due to decades of excessive mining, there has been a global decline in …

The most remarkable changes in the low-grade metamorphic rocks of slate and phyllite were the increases in void space and water content. The corrosion of mica, feldspar, and calcite increased the void space, and the formation of channels increased the free water content. Furthermore, the clay minerals and gypsum adsorbed more water …
