Abstract

PURPOSE: Provided is an economical preparation method of manganese sulfate with high purity, high yield and easy industrialization by using ferro alloy(Fe-Mn) electric furnace dust. CONSTITUTION: Manganese sulfate is prepared by the following steps of: mixing 43-45wt.% of concentrated H2SO4, 60-70wt.% of Fe-Mn electric furnace dust and 6-7wt.% of ferro manganese; heating at 95deg.C for 5hrs; filtering; adding 3-4wt.% of Zn powder to the filtrate for removal of heavy metals, concentrating and drying.

Description

Manganese sulfate manufacturing method {A PROCESS FOR PRODUCING MANGANESE SULFATE}

본 발명은 페로망간 황금철 전기로더스트를 이용하여 황산망간을 제조하는 방법에 관한 것이다.The present invention relates to a method for producing manganese sulfate using ferro-manganese golden iron electric furnace.

페로망간 합금철 전기로더스트에는 망간 30%가 포함되어 있고 페로망간에는 망간 70%, 철 15%가 포함되어 있다.Ferro-manganese ferroalloy contains 30% manganese and ferro-manganese contains 70% manganese and 15% iron.

본 발명은 상기와 같은 소재를 이용하여 황산망간을 제조하는 것이다.The present invention is to prepare manganese sulfate using the above materials.

종래의 페로망간 합금철 전기로더스트의 경우는 매립폐기물로 지정되어 땅에 매립하기 때문에 환경오염 등의 문제가 발생하고 있고 처리비용이 많이 드는 문제점이 있다.In the case of the conventional ferro-manganese ferroalloy electric furnace, it is designated as a landfill waste and is buried in the ground, thus causing problems such as environmental pollution and having a high cost of treatment.

본 발명은 상기 문제점을 해소하기 위해 페로망간 황금철 전기로더스트를 이용하여 황산망간을 제조하여 폐기물을 유용하게 이용할수 있게한 것이다.In order to solve the above problems, the manganese sulfate is manufactured by using ferro-manganese golden iron electric furnace to make the waste useful.

본 발명은 상기와 같은 종래의 결점을 시정하기 위하여 개발된 것으로 이를 더욱 상세히 설명하면 다음과 같다.The present invention was developed to correct the above-mentioned drawbacks as described in more detail as follows.

본 발명은 물에 대하여 농황산(순도98%) 43-45중량%, 페로망간 합금철 전기로더스트 60-70중량%, 페로망간 6-7중량%를 혼합하여 95℃로 5시간 가열하여 반응시키고 여과후 금속아연분말 3-4%를 넣어 중금속을 제거한후 농축, 건조하여 황산망간을 제조하는 것이다.In the present invention, 43-45% by weight of concentrated sulfuric acid (purity 98%), 60-70% by weight of ferro-manganese ferroalloy, and 6-7% by weight of ferro-manganese are mixed, heated at 95 ° C for 5 hours, and filtered. After adding 3-4% of metal zinc powder to remove heavy metals, it is concentrated and dried to produce manganese sulfate.

< 실시예 (1) ><Example (1)>

물 150g에 황산(순도98%) 65g을 넣고 페로망간 합금철더스트 100g과 페로망간 10g을 넣어 95℃로 5시간 가열하여 반응시키고 여과후 용액에 금속아연분말 5g을 넣어 중금속(pb,cd)을 제거한후 용액을 농축, 건조하여 황산망간(MnSo₄) 110g을 얻었다.Add 65 g of sulfuric acid (purity 98%) to 150 g of water, add 100 g of ferro-manganese alloy iron dust and 10 g of ferro-manganese to heat it for 5 hours at 95 ℃. After removal, the solution was concentrated and dried to obtain 110 g of manganese sulfate (MnSo ₄ ).

이와같이 제조된 본원 발명은 황산망간의 수율이 높아서 경제성이 있고 이렇게 제조된 제품은 미네랄과 같은 유용한 제품의 생산에 이용할수 있고 중금속을 아연말로 제거하기 때문에 안전하고 경제적이며 실용성이 있어서 산업화가 용이한 이점이 있다.The present invention prepared as described above is economical because the yield of manganese sulfate is high, and the product thus manufactured can be used for the production of useful products such as minerals, and heavy metals are removed with zinc powder, which is safe, economical and practical, and thus easy to industrialize. There is this.
