The process of recuperau00c7u00e7o ash zinc to obtenu00c7u00e7o of u00e0xio zinc with low levels of lead, cadmium and zinc metal applied in the elaboralau00c7u00e7o compost nutrient to use animal or plant; cu00c9lula industrial execuu00c7u00e7o process of recuperau00c7u00e7o zinc ash.Represented by a solution of inventive in the sectors of chemistry and metallurgy whose industrial activity converges in the production of waste material in the form of zinc ash, finding particular utility in the electroplating industry, the implementation and operation of the cell I. The inventive ndustrial for consolidation of the inventive process adds value to the residual material zinc ash.Because it gives a process with low energy consumption, because the energy in the demand is 77% resulting from the exotherm of oxidation of zinc, and the remaining 23% are provided by burning natural gas, and the resulting product main, in the form of zinc oxide and 95% The by-products.In the form of a particulate material containing each with different levels of zinc oxide, metallic zinc, cadmium and lead, and consequently with a variety of applications, such as for use as an input of nutrients for animal and plant production or production of zinc lingotres Zinc oxide 99% and also as raw material for the production production of zinc sulfate or zinc chloride.
