THE DEVIATION-FROM-EQUILIBRIUM EFFECT ON DISSOLUTION RATE AND ON APPARENT VARIATIONS IN ACTIVATION ENERGY - V. GIBBSITE SOLUBILITY AT 50°C AND PH 3 TO 9 IN 0.1 MOLAL NACL SOLUTIONS, A GENERAL MODEL FOR ALUMINUM SPECIATION, AND ANALYTICAL METHODS

Cama J.; Ayora C.; Lasaga A.C. (1999)

Dissolution rates of minerals depend on several factors. Among them, the factor measuring the deviation of the solution from equilibrium has not been sufficiently investigated. The dissolution rate of kaolinite as it would ...
THE EFFECT OF PH AND TEMPERATURE ON KAOLINITE DISSOLUTION RATE UNDER ACIDIC CONDITIONS

Cama J.; Metz V.; Ganor J. (2002)

The main goal of this paper is to demonstrate a new rate law describing the combined effect of pH (0.5 to 4.5) and temperature (25°C to 70°C) on kaolinite dissolution rate, under far from equilibrium conditions, as a step ...
THE EFFECTS OF ORGANIC ACIDS ON THE DISSOLUTION OF SILICATE MINERALS: A CASE STUDY OF OXALATE CATALYSIS OF KAOLINITE DISSOLUTION

Cama J.; Ganor J. (2006)

Most studies agree that the dissolution rate of aluminosilicates in the presence of oxalic and other simple carboxylic acids is faster than the rate with non-organic acid under the same pH. However, the mechanisms by which ...
