Dewatering coal polydisperse suspensions

Dewatering of fibre suspensions by pressure filtration

Dewatering of coal fines using a super absorbent polymer

403 The Journal of The South African Institute of Mining and Metallurgy JULY/AUGUST 2003 Introduction Coal preparation is used to upgrade run-ofmine coal before it is utilized by the end-user, primarily electric utility power plants. According to Fonseca1, the coal preparation process reduces the amount of noncombustible mineral impurities, acid-rain precursor sulphur-bearing minerals and hazar...

A Novel Approach for Beneficiation and Dewatering of Coal Fines for Indian Coal Preparation Plant

An attempt has been made to beneficiate the Indian coking coal fines by a combination of Spiral, flotation and Oleo Flotation processes. Beneficiation studies were also carried out on 0.5mm coal fines using flotation and oleo flotation by splitting at size 0.063mm.Size fraction of 0.5mm-0.063mm and -0.063mm size were treated in flotation and Oleo flotation respectively. The washability studies ...

Numerical study of freezing in polydisperse colloidal suspensions

We have established the solid–fluid coexistence region for a system of polydisperse hard spheres with near-Gaussian diameter distributions, as a function of polydispersity. Significantly, we observe a ‘terminal’ polydispersity above which there can be no fluid–solid coexistence. At the terminus the polydispersity is 5.7% for the solid and 11.8% for the fluid while the volume fractions are 0.588...

Spectral Ewald Acceleration of Stokesian Dynamics for polydisperse suspensions

In this work we develop the Spectral Ewald Accelerated Stokesian Dynamics (SEASD), a novel computational method for dynamic simulations of polydisperse colloidal suspensions with full hydrodynamic interactions. SEASD is based on the framework of Stokesian Dynamics (SD) with extension to compressible solvents, and uses the Spectral Ewald (SE) method [Lindbo & Tornberg, J. Comput. Phys. 229 (2010...
