Abstract
The combined reagents of sodium N-oleoylsarcosinate (SNOS) with metal ions (Ca(II), Mg(II), Cu(II), and Pb(II)) was employed to facilitate the separation of lepidolite from feldspar. The synergistic interaction mechanism of this combined reagent was systematically investigated via contact angle measurements, AFM, FTIR, species distribution calculations, and DFT calculations. The results suggested that Ca(II) exhibited the best selectivity for activating lepidolite flotation. SNOS was chemically adsorbed on the Ca(II)-activated lepidolite surface with an adsorption energy of −1248.91 kJ/mol while a lower adsorption energy of −598.84 kJ/mol of SNOS on Ca(II)-activated feldspar was calculated. Therefore, this combination of SNOS and Ca(II) is a promising reagent scheme for the efficient recovery of lithium from aluminosilicate ore.
期刊介绍：
The Transactions of Nonferrous Metals Society of China (Trans. Nonferrous Met. Soc. China), founded in 1991 and sponsored by The Nonferrous Metals Society of China, is published monthly now and mainly contains reports of original research which reflect the new progresses in the field of nonferrous metals science and technology, including mineral processing, extraction metallurgy, metallic materials and heat treatments, metal working, physical metallurgy, powder metallurgy, with the emphasis on fundamental science. It is the unique preeminent publication in English for scientists, engineers, under/post-graduates on the field of nonferrous metals industry. This journal is covered by many famous abstract/index systems and databases such as SCI Expanded, Ei Compendex Plus, INSPEC, CA, METADEX, AJ and JICST.
