The leaching kinetics of a sphalerite concentrate containing 38.25% zinc was studied in the
presence of biological and chemical ferric reagents. To produce the biological ferric reagent …

The kinetic of the reaction of sand with aqueous NaOH corresponding to the ratio
SiO2/Na2O= 2 was studied in a pressure vessel at 220° C and 2.7 MPa. Since the kinetic …

The dissolution of spherical particles in liquids is analyzed dynamically. Here, we consider
the case the dissolution of solute yields a solute-free solid phase in the outer portion of a …

In this study, an axisymmetric, transient model is used to investigate the effects of particle
shape in mass-diffusion-controlled dissolution process. Five particle shapes (sphere …

A mathematical model is proposed for a precipitation process of magnesium carbonate in a
heterogeneous stirred tank reactor. The model includes a description of dissolution of Mg …

The behavior of the dissolution of solid particles in liquids is modeled kinetically. It is
assumed that a surface layer exists near the solid—liquid interface; the diffusion of solute …

The dissolution of planar, cylindrical, and spherical particles in a stagnant liquid is analyzed
theoretically. Assuming that the diffusion of solute molecules is the rate-determining step, the …

The dissolution of solid particles in liquids involves the dissociation of solute molecules
through a surface reaction and the subsequent diffusion of these molecules toward the bulk …

In this research, parameters affecting the recovery of titanium dioxide from Iron slag sample
collected from Esfahan Steel Company, located in Esfahan province, Iran, were studied …

The kinetic invariant model proposed earlier for dissolution followed by chemical reaction of
large, monodisperse particles (AN Bhaskarwar, AIChE J., 37 (1991) 340–346) has been …
