Zinc processing - Zinc processing - Ores: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world's output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or

The results indicate that the particle size has little influence on the leaching efficiency of zinc while the influences of other factors are larger. The optimal leaching condition is: the reaction temperature is 80 C, the alkali concentration is 4.5 mol/L, and the leaching time is 1.5 h as well as the liquid- solid ratio is 10:1. In such conditions, the leaching efficiency can reach 82.22%

The Effects of some reaction conditions on leaching of zinc from zinc oxide ore with ammonium chloride solution are investigated.The results shows that leaching of zinc is about 90% under the optimum conditions which stirring rate is 300 r/min,average particle size of ore is 75μm, temperature is above 90℃,ammonium chloride concentration is 5 mol/L and reaction time is 4 h.The iron

The behavior of zinc leaching in these tests was similar to that obtained from oxidized zinc ore by Abdel Aal (1997). In Abdel Aal's work, the sulfuric acid concentration also had a pronounced effect on the extraction of zinc despite the fact that different minerals and different experimental conditions were used. At the same time, excessive sulfuric acid gave no benefit in terms of enhancing
