Energy-saving and environmentally-friendly methods extraction of tungsten and tungsten ore concentrate – an integral part of environment and human healt / L. A. Chernenko, N. V. Solovieva // Energy, energy saving and rational nature use. – 2014. – № 2. – Р. 18–22.https://repository.pdmu.edu.ua/handle/123456789/15487It is shown that tungsten is extracted from tungsten ores and concentrates in sodium chloride-sodium metasilicate melts into the halide phase at a temperature of 1050 to 1050-1100°C. The compositions of the melts that provide the extraction efficiency as high as 99% and maximal ratios of separation of the components between the phases are chosen.entungstenthe halide-tungstateArticle669.1+669.2/8
