Surface tension of flotation solution and its influence on the selectivity of the separation between apatite and gangue minerals
(SOC MINING METALLURGY EXPLORATION INC, 2009)
This work presents and discusses the influence of the surface tension (gamma(LV)) of methanol/water mixtures on the flotation response of apatite versus gangue minerals conditioned with flotation reagents (75 g/t cornstarch ...
Effect of biosolids and their main components in the concentration of copper sulphide ores

Alternativas de processo para concentração do minério fósforo-uranífero de Itataia
(Universidade Federal de Minas GeraisUFMG, 2010-09-30)
The search for selectivity in flotation systems involving slightly soluble minerals has been the motivation for several investigations. Fundamental studies as well as laboratory and pilot scale tests have been performed ...
Efeito da granulometria na flotação de quartzo
(Universidade Federal de Minas GeraisUFMG, 2005-03-28)
Mineral particles of different sizes are present in flotation slurries. The particles size range varies from of millimetres to micrometers. Industrial practice and several investigations show that the extent of flotation ...
Aminas na flotação de minério de ferro
(Universidade Federal de Minas GeraisUFMG, 2013-08-22)
The main collectors utilized in the reverse cationic flotation of iron ores belong to the amines group, more specifically the etheramines. In addition, depressants (starches), dispersants, pH modulators, etc. are also ...
Emulsificação de coletor para flotação de grafita
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2020-03-20)
Pure graphite is a naturally hydrophobic mineral. Graphite flotation processes use
hydrocarbon collectors, mainly kerosene and diesel oil. These compounds have low
solubility and dispersion in the aqueous flotation ...
Separation of silica from bauxite via froth flotation
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This paper reports an innovative development: concentrating gibbsite via reverse froth flotation in order to obtain a metallurgical-grade bauxite concentrate. Tailings from an industrial plant have undergone attrition ...
