MANUFACTURING METHOD OF COMPOSITE MINERALS FROM ELECTRIC ARC FURNACE DUST, FERROMANGANESE PLANT DUST, PULVERIZED WASTE BATTERY OR A MIXTURE THEREOF

摘要

PURPOSE: A manufacturing method of composite minerals from electric arc furnace dust, ferromanganese plant dust, pulverized waste battery or a mixture thereof is provided to obtain a composite mineral in which inorganic iron, sulfate zinc, manganese sulfate and cobalt sulfate are existed as in a mixed form.;CONSTITUTION: A manufacturing method of composite minerals comprises the following steps: reacting raw material selected from electric arc furnace dust, ferromanganese plant dust, pulverized waste battery or a mixture thereof with sulfuric acid water(60:40%); solidifying heavy metal within molten material into zinc powder and filtering the molten material; and heating and drying the filtrate and to obtain a composite mineral in which inorganic iron, sulfate zinc, manganese sulfate and cobalt sulfate are existed as in mixed form. In the reaction step with sulfuric acid water, the specific metallization is added in 1-15 weight% range of the total amount of the reactant. The metallization is ferromanganese powder, zinc powder, scrap iron powder, iron powder selected from waste battery crushed material or steel factory electric arc furnace dust reduced metal.;COPYRIGHT KIPO 2013
