this study investigates removing ash and pyrite sulphur from bitumen by column flotation process. central composite design (ccd) of response surface methodology (rsm) was applied for modeling and optimization of the percentage of ash and pyrite sulphur removal from bitumen. the effects of five parameters namely the amounts of collector and frother agents, particle size, wash water rate and feed...

For over two decades, LOOP (French acronym for Process Observation and Optimization Laboratory) researchers have been working at developing and/or improving specific sensors for flotation columns and their use for automatic control of this process. Several papers have already been published for the mineral processing industrial and scientific community in peer-reviewed journals and conference p...

The mixing characteristics of industrial flotation columns were investigated using computational fluid dynamics (CFD). Particular emphasis was placed on the clarification relationship between liquid and solids parameters such as mean residence time axial dispersion coefficients. effects particle size bubble in column also studied. An Eulerian-Eulerian method applied to simulate multiphase flow,...

The froth flotation technique can be considered one of the most efficient methods for separation minerals. Prior to utilizing any physicochemical method, size mined ore must decreased facilitate release valuable materials. This practice, along with increased exploitation ores that carry fine mineral particles caused production and ultrafine which are difficult recover classical enrichment metho...
