Abstract

The method of separate floatation dressing comprises (a) abrading the ore containing arsenic sulfide and pyrite for the liberation, (b) maintaining the mineral solution in the pH range of 10-11 with portland cement as an inhibitor for arsenic sulfide, (c) floating pyrite by adding a collecting agent and a bubbling agent to the solution, and (d) dressing the high grade arsenic sulfide through refining two or three times.

Description

황철광과 유비철광의 분리 부선방법Separation and Floating Method of Pyrite and Non-ferrous Ore

본 발명은 황철광과 유비철광의 분리부선 방법에 관한 것으로서, 종래의 부선 방법으로는 선광할 수 없었던 고품위의 황철광 및 유비철광을 보다 간단하고 높은 실수율로 생산할 수 있는 선광 방법이다.The present invention relates to a method for separating barges of pyrite and arsenic iron, and is a beneficiation method that can produce high-quality pyrite and arsenic iron, which could not be beneficiated by a conventional barge method, at a simpler and higher real rate.

본 발명의 선광 방법을 상세히 설명하면 다음과 같다.The beneficiation method of the present invention will be described in detail as follows.

황철광 및 유비철광이 함유된 원광을 단체분리(單體分離)되게 마광(麻鑛)하여 포트랜드 시멘트(Ig-loss 0.6%, Ins-Res 0.25%, SiO220.2%, Al2O34.8%, Fe2O33.4%, CaO 65.6%, Mgo 2.6%, SO31.9%의 성분을 갖는 포트랜드 시멘트와 같은 성분 및 조성을 포함함)로 pH를 10.0-11.0 정도로 유지하면서 조건을 부여한 후, 표수제 (

) (예 : 포타슘 아밀 잔세이트) 50-100g/T, 그리고 기포제(起泡劑)(예 : 파인오일)를 25-30g/T씩 각각 첨가한 다음 황철광을 부유시켜 회수하고, 정선을 2-3회 행하여 고품위 황철광을 회수한다. 황철광을 회수한 광미중에서 황상으로 광액의 pH5.0-6.0정도로 유지하면서 포수제 및 기포제를 각각 첨가하여 유비철광을 부유시켜 2-3회 정선을 거쳐 고품위 유비철광을 생산하였다.Portland cements (Ig-loss 0.6%, Ins-Res 0.25%, SiO 2 20.2%, Al 2 O 3 4.8%) Containing the same components and composition as Portland cement having 3.4% Fe 2 O 3 , 65.6% CaO, 2.6% Mg, and SO 3 1.9%), and maintaining the pH at about 10.0-11.0.

(Example: potassium amyl xanthate) 50-100g / T and foaming agent (e.g., pine oil) are added 25-30g / T, respectively, and then recovered by floating pyrite, 3 times to recover high quality pyrite. In the tailings of recovering the pyrite, the sulfur phase was maintained at pH 5.0-6.0 of the mineral solution while adding a catcher and a foaming agent, respectively.

이상과 같은 방법에 의하면, 포트랜드 시멘트는 유비철광에 대하여 현저한 억제작용(抑制作用)을 하면서 황철광을 부유시키게 되므로 황철광과 유비철광의 분리 부선이 매우 효과적으로 이루어지는 잇점이 있다.According to the above method, since Portland cement floats pyrite while having a significant inhibitory effect on the arsenite, separation barges of pyrite and arsenite are very effective.

이상과 같은 방법에 의하여 얻어진 황철광 정광은 S : 48%, Fe : 41%, As : 0. 05-0.1%이고 유비철광은 As : 30%이상의 것이 생산된다. 이하 본 발명의 실시예를 들면 다음과 같다.The pyrite concentrate obtained by the above method is S: 48%, Fe: 41%, As: 0.05-0.1%, and arsenic iron ore is produced with more than As: 30%. An embodiment of the present invention is as follows.

상기 실시예에서 포트랜드 시멘트로 광액의 pH를 10.0-11.5정도로 유지하면서 유비철광을 억제시키고 포타슘 아밀잔제이트를 85g/T, 파인 오일 25g/T을 각각 첨가하여 황철광을 부유시켜 회수하는 것이 분리부선 방법으로 가정 적합한 선광 방법의 조건이기 때문이다.In the above embodiment, Portland cement maintains the pH of the mineral solution at about 10.0-11.5 while suppressing arsenite, and adding 85 g / T of potassium amylzanate and 25 g / T of fine oil, respectively, to recover the pyrite by floating pyrite. This is because it is a condition of the beneficiation method suitable for the assumption.

이 방법을 실시한 결과 비소(As)를 0.050-0.1%로 저하시키며 실수율은 78.5%정도로 황철광 정광을 생산할 수 있었다. 이와같이 본 발명은 포트랜드 시멘트를 사용하여 가장 저렴하면서도 최초로 황철광의 분리부선 방법이 확립된 신규한 발명이다.As a result of this method, arsenic (As) was reduced to 0.050-0.1% and the yield rate was about 78.5%. As described above, the present invention is a novel invention in which the method of separating barges of pyrite is established for the first time with the cheapest using portland cement.
