Sluicing SpringerLink
Sluicing. Sluicing is a gravity concentration method in the chute to separate particles by the difference of motion state produced by the water flow moving along the inclined plane. In the middle of the nineteenth century, the belt sluice by mechanical transmission appeared, becoming the main separation equipment of fine-grained The extraction of lithium from poor aluminosilicate raw materials (below 3% Li 2 O) owing to high energy costs, high consumption of reagents, and multistage production is uncompetitive with extraction from hydromineral (salt) deposits.

Extraction of Lithium from Petalite Ore by Chloride
For these reasons, the extraction of lithium from poor ores using lime and sulfuric acid technologies is unprofitable. Recently, attempts have been made to reduce the cost of processing through waste disposal. It was pro-posed [8] to use the residues of lithium ores processed with the classical lime technology (sintering with limeLithium is an essential ingredient in batteries for electric vehicles (EVs), and the global energy transition has seen prices of lithium compounds rocket. In January 2021, a tonne of battery-grade lithium carbonate cost 40,000–60,000 yuan (US$5,600–8,400).

Recent advances in lithium extraction from lithium-bearing
The current lithium production based on the three types of resources decreases in the order of brine-type (∼64%), pegmatite-type (∼29%), and clay-type (∼7%). Among these, brines and several ores (e.g., spodumene, lepidolite) were considered valuable for Li extraction due to the economic enrichment of lithium.This review adds to the public domain literature on the extraction of lithium from mineral ores. The focus is on the pyrometallurgical pre-treatment of spodumene. Information on the phase transformation from α to β, the heat treatment methods as well as the behavior of various compounds in the roasting processes are evaluated.
