Research ArticleOpen accessIn the author namesThe Application of Numerical Taxonomy Technique in the Iron Ore Flotation to Determine Appropriate pH and Particle Size DistributionRasoul Khosravi, Fahimeh Dehghani, Hossein Siavoshi et al.The numerical taxonomic technique is one of the multivariate decision-making techniques for assessment and ranking. It is widely used for planning and development studies. In this research, flotation experiments were conducted for Band Narges mine iron ore using different pH and particle size ranges. Numerical taxonomy technique, as one of the most important multi-attribute decision-making techniques, was used to determine … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 24 Dec 2020 · 6,699 accessesView PDF Cite

Research ArticleOpen accessIn the author namesNew Insights into the Pre-Concentration of Alunite from a Siliceous ore using Froth FlotationFahimeh Dehghani, Halimeh Askari-Sabzkoohi, Tathagata GhoshAlunite is the main non-bauxite source of aluminum. Due to the low Degrees Of Freedom (DOF) of alunite, froth flotation, as a pre-concentration method, is a viable alternative to increase selectivity in downstream processes. The current study was aimed at investigating the pre-concentration of alunite using micro-flotation. In the first step, an optical microscope studies were done to determine DOF … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 20 Dec 2020 · 7,184 accessesView PDF Cite
