Abstract

PURPOSE: A method for manufacturing manganese sulfate, zinc sulfate and ferrous sulfate from manganese dioxide and electric furnace dust of steelworks is provided which can be economically utilized in such a field as minerals for manufacturing animal feed by obtaining a product in which manganese sulfate, zinc sulfate and ferrous sulfate are coprecipitated. CONSTITUTION: The method for manufacturing manganese sulfate, zinc sulfate and ferrous sulfate from manganese dioxide and electric furnace dust of steelworks is characterized in that manganese sulfate, zinc sulfate and ferrous sulfate are obtained in the coprecipitated state by sequentially performing processes of heating the mixture to 750 deg.C by mixing one material selected from pitch, bunker C oil, light oil, briquette, molasses and starch with a mixture of manganese dioxide and electric furnace dust after mixing manganese dioxide with electric furnace dust, and heating and reacting the resulting solution to 95 deg.C for 4 to 6 hours by putting the heated mixture into an aqueous sulfuric acid solution.

Description

이산화망간, 제강공장 전기로더스트로부터 황산망간, 황산아연, 황산제1철을 제조하는 방법{Method for manufacturing manganese sulfate, sulfate zinc and ferrous sulfate from electric furnace dust of manganese dioxide and steel works}Method for manufacturing manganese sulfate, sulfate zinc and ferrous sulfate from electric furnace dust of manganese dioxide and steel works}

본 발명은 이산화망간과 제강공장의 전기로더스트에서 황산망간, 황산아연, 황산제1철을 제조하는 방법이다.The present invention is a method of manufacturing manganese sulfate, zinc sulfate, ferrous sulfate in the electric furnace of manganese dioxide and steelmaking plant.

이산화망간에는 망간 50%, 철 15%가 포함되어 있고 제강공장의 전기로더스트에는 아연 25%, 철 25%가 포함에 되어 있다.Manganese dioxide contains 50% manganese and 15% iron, and the electric furnace of the steel mill contains 25% zinc and 25% iron.

본 발명은 상기 소재로부터 황산아연, 황산망간, 황산제1철을 생산하여 동물사료 첨가용 미네랄을 경제성 있게 제조하는 것이다.The present invention is to produce zinc sulfate, manganese sulfate, ferrous sulfate from the material to economically produce minerals for animal feed.

이산화망간은 가격이 싸고 구하기가 용이하나 일산화망간으로 만들어야 황산에 반응이 될 수 있기 때문에 제조경비가 많이드는 불편이 있고 전기로더스트는 매립할 경우토양오염의 문제가 있고 염소성분이 있어서 반드시 가열해야 이를 안전하게 제거할 수 있는 특징이 있다.Manganese dioxide is inexpensive and easy to obtain, but it is inconvenient to manufacture due to manganese monoxide, which can be reacted with sulfuric acid. There are features that can be removed.

본 발명은 이를 위해 연구한 결과 이산화망간과 전기로더스트에 핏치, 방카C유, 경유, 연탄, 당밀, 전분중에서 하나를 택하여 혼합한 후 가열로에 넣고 750℃로 2시간이상 가열하여 이산화망간은 일산화망간으로 변화시키고 전기로더스트는 염소성분이 제거되게하여 이를 황산에 반응시켜 황산아연과 황산망간, 황산제1철을 동침상태로 제조하여 동물사료 첨가용 미네랄 제조에 사용할 수 있게한 것이다.The present invention has been studied for this, and one of the pitch, banca C oil, light oil, briquettes, molasses, starch and mixed in the manganese dioxide and electric furnace, put into a heating furnace and heated at 750 ℃ for more than 2 hours manganese dioxide The chlorine component was removed and reacted with sulfuric acid to produce zinc sulfate, manganese sulfate, and ferrous sulfate in a state of being immersed, so that it could be used to prepare animal feed minerals.

이하 실시례에 따라 상세히 설명하면 다음과 같다.When described in detail according to the following examples.

<실시례 1><Example 1>

이산화망간 50g, 전기로더스트 100g, 연탄 15g을 넣고 750℃로 2시간 가열하면 일산화망간 50g과 전기로더스트 100g이 만들어진다.50g of manganese dioxide, 100g of electric roast, and 15g of briquettes are heated at 750 ° C. for 2 hours to make 50g of manganese monoxide and 100g of electric roast.

이를 황산수용액에 넣어서 95℃로 4-6시간 반응시키면 황산망간, 황산아연, 황산제2철이 생산되고 이때 페로망간 10g을 넣어서 황산제2철을 황산제1철로 환원시키고 아연분말 3g을 넣어서 중금속을 제거하고 용액을 여과하여 농축, 건조하여 무수상태의 황산망간 90g, 황산아연 85g, 황산제1철 85g이 동침된 제품 260g을 얻었다.It is added to an aqueous solution of sulfuric acid and reacted at 95 ° C for 4-6 hours to produce manganese sulfate, zinc sulfate, and ferric sulfate. At this time, 10 g of ferromangan is added to reduce ferric sulfate to ferrous sulfate, and 3 g of zinc powder is added to the heavy metal. The solution was filtered, concentrated, and dried to obtain 260 g of a product in which 90 g of anhydrous manganese sulfate, 85 g of zinc sulfate, and 85 g of ferrous sulfate were impregnated.

이렇게하므로서 황산망간, 황산아연, 황산제1철이 동침된 제품을 얻어 동물사료제조용 미네랄과 같은 분야에 경제적으로 활용할수 있는 이점을 얻는 것이다.In this way, manganese sulphate, zinc sulphate, and ferrous sulphate are impregnated to obtain products that can be economically utilized in fields such as minerals for animal feed.
