Study on process mineralogy of clay-type lithium ore in central region of Yunnan province
Background
The clay-type lithium resource founded in central region of Yunnan province will become a crucial lithium resource in the future because of its large reserves and superior geographical location. The technological mineralogical characteristics are extremely important for clay-type lithium resource separation and extraction. Therefore, in this paper, the chemical composition, mineral composition, mineralogical characteristics, distribution size and symbiotic relationship of main minerals of clay-type lithium ore in the central region of Yunnan Province were analyzed.
Methods
The X-ray fluorescence spectrum (XPS), X-ray diffraction analysis (XRD), chemical multi-element analysis, thermal analysis, acid dissolution test, microscope, and mineral liberation analyser (MLA) were used. In addition, for the first time, the enriched ore samples were manually selected under the microscope. The occurrence state of lithium was investigated by chemical multi-element analysis and XRD quantitative analysis.
Significant findings
The results revealed that the ore was composed of 16 kinds of minerals and lithium exists mainly in the form of cookeite. Due to the distribution size and symbiotic relationship, extremely fine grinding particle size is required for cookeite separation. Meanwhile, the main gangues are diaspore, boehmite and kaolinite. Therefore, exploring the effects of them on the lithium extraction is important for the development of selective roasting additives and leaching reagents.
期刊介绍：
Journal of the Taiwan Institute of Chemical Engineers (formerly known as Journal of the Chinese Institute of Chemical Engineers) publishes original works, from fundamental principles to practical applications, in the broad field of chemical engineering with special focus on three aspects: Chemical and Biomolecular Science and Technology, Energy and Environmental Science and Technology, and Materials Science and Technology. Authors should choose for their manuscript an appropriate aspect section and a few related classifications when submitting to the journal online.
