Fundamental concepts of cake filtration - cake compressibility, liquid drag-pressure drop relationships, average porosity, and external mass balance - are presented. Two distinct approaches to the formulation of cake filtration rate, the classical and the modern theories, are critically reviewed. The definition of average specific cake resistance is re-examined. The equivalent specific cake resistance for a compressible cake is shown to be the harmonic mean of local specific cake resistances. Weaknesses of the classical theory in data analysis are pointed out. Recognition of the cake-filter medium interface by the modern theory as the rate-controlling part of the filtration system is stressed.

Empirical correlations for the prediction of cake dewatering characteristics HOSTEN, C.; SASTRY, KVS (Elsevier BV, 1989-1) The irreducible equilibrium saturation and dewatering kinetics of vacuum-dewatered filter cakes are studied. Limitations of available empirical correlations for cake dewatering characteristics are presented. The mechanisms of air displacement dewatering are delineated as no-air-flow and air-flow dewatering regimes, and new nondimensional groups combining the pertinent parameters in each regime are proposed for correlating the equilibrium saturation. On the basis of the capillary flow dynamics, a nondimensio...
Ternary-mixture grinding of ceramic raw materials Ipek, H; Ucbas, Y; Hoşten, Çetin (Elsevier BV, 2005-01-01) Batch experiments were carried out on the dry ball milling of commonly used ceramic raw materials quartz, kaolin and feldspar, singly and as ternary mixtures. The modified form of the Charles energy-size reduction equation was used to calculate the energy consumed by each of the components in the mixture. The results confirmed the validity of the mass fraction hypothesis for energy split between the components that had been defined and verified for the binary mixtures of equal-density minerals. The distribu...
Adsorption of dithiophosphate and dithiophosphinate on chalcopyrite Guler, T; Hicyilmaz, C; Gokagac, G; Ekmeci, Z (Elsevier BV, 2006-01-01) Electrochemical behavior of chalcopyrite was investigated in the absence and presence of dithiophosphate (DTP) and dithiophosphinate (DTPI), selective thiols against Fe-sulfides in the flotation of sulfide ores, in potentiostatically controlled electrochemical condition. Diffuse reflectance Fourier transformation (DRIFT) spectroscopy was applied to determine the type of adsorbed collector species, and Hallimond tube flotation tests were performed to clarify the role of polarization potential and thiol colle...
The bond work index of mixtures of ceramic raw materials Ipek, H; Ucbas, Y; Hoşten, Çetin (Elsevier BV, 2005-08-01) The Bond method of grindability was applied to ceramic raw materials (quartz, kaolin and feldspar) and to their binary and ternary mixtures. The Bond work indices of the admixtures containing a softer component (kaolin) were found to be greater than the weighted average of the work indices of the individual components in the mixture. As a result, separate grinding of ceramic raw materials seems to require less specific energy input than grinding them in admixtures.
Hydrometallurgical processing of nontronite type lateritic nickel ores by MHP process Kose, C. H.; Topkaya, Yavuz Ali (Elsevier BV, 2011-04-01) The research work presented in this paper determined the optimum conditions at which nickel and cobalt could be obtained at maximum efficiency from the column leach liquor of the lateritic nickel ore existing in Gordes region of Manisa in Turkey by performing effective hydrometallurgical methods. This column leach solution was initially neutralized and purified from its basic impurities by a two-stage iron removal process, nickel and cobalt were precipitated in the form of mixed hydroxide precipitate from t...
