摘要：
Laboratory investigations have been carried out on the direct leaching of zinc concentrate with ferric chloride solutions and the recovery of zinc from the chloride leach liquors. The use of 2 M FeCl3 and 0.2 M HCl was found to give the optimum recovery of zinc into solution. The presence of impurities, such as pyrite, increases the rate of dissolution of zinc and reduces the consumption of ferric chloride. Zinc was recovered from the chloride solutions by selective precipitation as zinc ammonium chloride.
