In order to alleviate the pressure on supply of lithium resources, this research proposes use binary/ternary collectors with high selectivity and collecting ability enhance flotation purification low-grade zinnwaldite ore. The binary collector is a mixture dodecylamine polyoxyethylene ether DL-2-octanol. A added first, followed by sodium oleate, known as ternary collector. Under acidic conditions, recovery Li2O in concentrate was increased 8.26% 13.70% collector, compared ether. enhanced dispersibility single while co-adsorption strengthened hydrophobic nature surface. Consequently, particles, after application displayed inter-particle flocculation attachment bubbles within 60×10−9 m other particles. Ternary exhibited capacity lower critical micelle concentration surface tension, subsequently inducing denser thicker layer through electrostatic forces, interactions, chemical reactions. objective facilitate resources from ores meet needs sustainable development.

Dissolution of Lithium Contained in Lepidolite Using Ascorbic Acid: Kinetic and Modeling Analysis

Materials, Journal Year: 2024, Volume and Issue: 17(22), P. 5447 - 5447

Published: Nov. 7, 2024

In this work, a kinetic study and modeling of the decomposition rock sample in an ascorbic acid medium with high content lepidolite phase were carried out, results which are great importance due to sample’s lithium (Li) content. The was characterized by X-ray diffraction (XRD), inductively coupled plasma atomic emission spectroscopy (ICP-AES) photoelectron (XPS), mineral species detected lepidolite, at 65.3%, quartz, 30.6%, muscovite, 4.1%, quantitative chemical analysis indicating presence elements such as Li, Si, K, Na, O, Al and, lesser extent, Fe Ti; highlights that Li present 3.38%. Lithium element kinetics performed, resulting curves comprising induction period, progressive conversion stabilization; highlighted reaction progressed during first two periods, obtaining order (n) 0.4307 for period activation energy (Ea) 48.58 kJ mol−1, followed n = 0.309 Ea 25.161 mol−1. This suggested mixed control regime lower temperature ranges, transition from transport temperatures, nature concentration effect showing predominates. parameters expressions both periods obtained, calculated experimental data do not major discrepancy.
