Dissolution kinetics of sphalerite in acidic ferric chloride leaching
(ELSEVIER SCIENCE SA, 2005)
This paper presents a study for leaching kinetics of sphalerite concentrate in FeCl3-HCl solution. The shrinking core model was applied to the results of experiments investigating the effects of stirrer speed of 200-600 ...
Dissolution kinetics of malachite in ammonia/ammonium carbonate leaching
(ELSEVIER SCIENCE BV, 2005)
The leaching of oxide copper ore containing malachite, which is the unique copper mineral in the ore, by aqueous ammonia solution has been studied. The effect of leaching time, ammonium hydroxide, and ammonium carbonate ...
