Abstract

Reaction crystallization process optimization for the production of K2SO4 with low-grade salt lake leonite ore in Qinghai, China.

The role of Mg value and moisture content of decomposed products during the decomposition process of carnallite in aqueous solution: a novel monitoring method

“…The process parameters of the material ratio, water addition, and operating temperature are sensitivity for the objective of product purity and recovery. 8 From the reactions of eqn ( 1)-( 3), we found that the amount of water is critical to the decomposition process of carnallite in an aqueous solution. Usually, the detection and assessment of the reactive process of carnallite decomposition are operated by analyzing the entire chemical compositions of E(L) or F(L).…”

“…6 A source of KCl is the carnallite double salt, which has the composition KCl$MgCl 2 $6H 2 O or KMgCl 3 $6H 2 O, and is either obtained as the ore or recovered from brine that favors carnallite. [7][8][9] Carnallite is treated with fresh water to dissolve MgCl 2 and keep KCl in the crystalline state. Then, KCl otation from the mixed salts is carried out using an amine as the collector.…”
