| titleOfInvention | Process for manufacturing sulfate of zine fertilizer from dust in electric furnace |
| abstract | The present invention relates to a method for producing zinc sulfate as an electric furnace, and more specifically, to an electric furnace which contains at least 25% of a zinc component in sulfuric acid solution and reacted for 7-8 hours to form sulfate in a solution. The first step and the second step of separating iron from the solution by adding 1.5-2.0% of permanganate to the sulfated electric furnace solution to form iron as a precipitated coagulant, and the solution separated from iron 0.5-1.0% of zinc powder is added to replace heavy metals such as lead with zinc sulfate to form precipitated crystals, which are separated from the solution, and the iron and heavy metals are removed to pH 4 and cooled. The fourth step of obtaining zinc sulfate through the process of drying or drying is sequentially performed to produce zinc sulfate from the electric furnace. Improve the Utilization value and improve the quality of the resulting zinc sulphate sikimyeo final waste that will be used as an additive in cement production. |
