Pumping Oil Sand Froth
Froth is the basis to the extraction of bitumen from oil sand. Its components include sand, bitumen, water, and air. The technology of extraction and processing is evolving toward lower temperature of operation where the volumetric content of air and viscosity of bitumen challenge pumping. To improve the efficiency of froth handling pumps it is important to adapt the technology from other indus...
متن کاملFroth flotation of phosphate rock
The development of froth flotation is traced from its earliest-known use through the discoveries leading to the present knowledge of the science. The factors influencing the flotation of non-sulfide and non-metallic minerals are discussed, and the machines used in commercial flotation operations are described. Experimental work on the flotation beneficiation of phosphate rock is presented as an...
متن کاملSoap and the Interstellar Froth
We investigate, whether the alleged failure of standard photoion-ization codes of the Diffuse Ionized Gas (DIG) is simply caused by geometrical effects and the insufficient treatment of the radiative transfer. Standard pho-toionization models are applicable only to homogeneous and spherical symmetric nebulae with central ionizing stars, whereas the geometry of disk galaxies requires a 3D distri...
متن کاملUnderstanding Froth Behaviour with Cfd
This paper will discuss the use of CFD in foam and froth modelling. The physics of froths is introduced and the methodology of combining the models for each phase into a complete description is reviewed. The utility of the CFD model is illustrated in two ways: First the equations are solved explicitly, giving a clear interpretation of process variables and their importance. Second, an example o...
متن کاملConcentration of bauxite fines via froth flotation (
Companhia Brasileira de Alumínio (CBA) has bauxite processing plants at Poços de Caldas and Itamarati de Minas, and a new processing plant at Miraí that has been operating since June, 2008; all of them are in the State of Minas Gerais. The plants haveunits for the crushing, scrubbing and screening operations. The screened oversize is the concentrate or washed bauxite. At Itamarati de Minas, the...
