Aiming at the problems of low utilization rate spodumene resources and serious environmental pollution, our team proposes a clean process to produce manganese-silicon alloy for lithium enrichment by carbothermal reduction spodumene. In this process, melting point viscosity slag phase are very high, which affects discharge slag–metal separation. Therefore, experiment considers addition CaO as slagging agent based on previous tests analyzes under different contents. When content is 30%, mainly Ca2Al2SiO7; 99.02%; direct yield 89.12%; 1260 °C. It can melt wrap before removing alloy, has heat preservation oxidation resistance. The 1360 °C 0.11 Pa·s, within optimum range in actual industrial production. Experiments show that beneficial removal separation metal, lays good foundation industrialization development improves economic benefits whole process.

Preparation of Lithium Carbonate from Manganese-Containing Desorption Solution from Salt Lakes via an Organophosphoric Acid Extraction System

Separations, Journal Year: 2025, Volume and Issue: 12(4), P. 98 - 98

Published: April 15, 2025

Adsorption is a popular method for the recovery of low-grade lithium. It low-cost and highly efficient way to treat solutions with low lithium concentrations. The impurity content determines industrial application. This study investigated novel strategy remove divalent cations from desorption solution containing Mg2+, Ca2+, Mn2+, generated by manganese absorbent using an organophosphoric acid, followed precipitation carbonate concentrated raffinate evaporation. Di(2-ethylhexyl)phosphoric acid (P204) was selected as preferred extractant. saponification degree were determined, extraction parameters (pH, extractant concentration, phase ratio) investigated. A three-stage countercurrent process tested. Removal efficiencies Mn2+ manganese-containing exceeded 99%, leaving <1.0 mg/L in raffinate. evaporated >23 g/L total concentration lithium-rich approximately 10.0 mg/L. Further conversion sodium carried out prepare battery-grade product purity 99.83%. present work may provide means solution.
