Abstract
Improvements introduced in the object of the main patent nº 304,601 granted on October 15, 1964, by: "A procedure for the recovery of zinc from ferrites", from the roasting of complex minerals containing iron, zinc, copper and lead, characterized in that in a first stage the flotation of these minerals is carried out, obtaining two concentrates, as a consequence of this flotation, which are subjected to roasting, recovering the zinc present in both roasting products, in the form of ferrites, as well as the remaining contained metals in the ferritic products, in a second stage, the ferric products obtained in the previous stage are subjected to leaching with concentrated sulfuric acid of 300 g/l, verifying the reaction at a temperature between 90 and 95ºC, and finally in a third stage the solution resulting from the leaching is neutralized with sintered blender, or with any other compound containing to zinc, which separates most of the iron present in the form of basic sulfate that carries part of the harmful impurities.
