| titleOfInvention | Method for simultaneously and comprehensively recycling zinc ash and high-arsenic zinc oxide in iron and steel plant |
| abstract | The invention provides a method for simultaneously and comprehensively recycling zinc ash and high-arsenic zinc oxide in an iron and steel plant. A great deal of iron in the zinc ash is recycled by using unsaturated fatty acid (saponified) and tea saponin intermixture in tea-oil dregs in a flotation manner; the zinc ash (subjected to flotation) and the high-arsenic zinc oxide in the iron and steel plant are respectively leached by using sulfuric acid; As<3+> in the high-arsenic zinc oxide is rapidly oxidized by using peroxy-sodium carbonate; corresponding indissolvable arsenate is generated after As<3+> is oxidized into As<5+> in the presence of Fe<3+> and Fe<2+>, and arsenic in the solution is eliminated by virtue of a secondary arsenic elimination method; zinc powder is purified to generate zinc sulfate, and the purpose that two varieties of waste slags are simultaneously and comprehensively recycled is achieved. |
