The leaching kinetic data is analyzed using graphical and statistical methods and it is inferred that the dissolution kinetics of zinc sulfide follows the shrinking core model. A kinetic model is Dissolution kinetics of glassy and crystalline As2S3 in Dec 01, 1997 · Dissolution kinetics of glassy and crystalline As2S3 in aqueous sodium sulfide and hydroxide 1. Introduction.

Geochimica et Using kinetic geochemical testwork to assist with mine Kinetic testwork is needed because sulfide oxidation rates vary with the specific type of reactive sulfide, including mineralogy s yrite, pyrrhotite, (e.g. p chalcopyrite, etc), thermo-barometric and structural evolution metamorphic grade and deformation (e.g.

THE EFFECT OF DISSOLVED OXYGEN ON THE

(1 < pH <3) the kinetics of sulfide aqueous dissolution is significantly different among different sulfide phases, e.g., PbS, ZnS, CuFeS2' AsFeS, and FeS2' Whereas sorne sulfides such as pyrite, galena, and arsenopyrite dissolve remarkably slower in the absence of dissolved oxygen, the dissolution rates of other sulfides (e.g., sphaleri te and chalcopyri te) are independent of the dissolved oxygen
