Flotation occurs as a result of bubble-particle attachment. This is controlled by the particle surface properties which are created by surface liberation of valuable minerals and collector adsorption within the chemical environment. This paper examines the contribution of both collector dosage and liberation of valuable minerals...
Flotation of Chalcopyrite: Four kinetic models are tested on batch flotation time-recovery profiles. A statistical analysis of data demonstrated that the flotation rate constant corresponded to a first-order model with rectangular distribution of floatabilities given by the equation：ε=ε∞{1-1.
kt [1 – e-kt]}. The effect of size distribution on the flotation behaviour of...

Vibrational spectroscopy and XPS have been used to investigate the interaction of n-octanohydroxamate with the surfaces of chrysocolla and other oxide copper minerals, as well as with the native oxide on copper metal. XPS investigations of low collector coverage at pH 9.5 confirmed that copper hydroxamate...

Compañía Minera Huasco (CMH) operates an iron pellet plant in central Chile. CHM desired to produce a low silica pellet for the export market wher the SiO 2 grade should not exceed 1.5%. It is common practice in other countries to float quartz from hematite with relative ease. However, the silicates...

Флотация один из основных и старейших методов для извлечения золота, известный еще с 30-х годов прошлого века. Флотация, в буквальном значении «плаванье на поверхности воды» — технологический процесс разделения мелких твёрдых частиц в водной среде. Основа...
