본 발명에 의하면, 단순히 원광을 잘게 부순 후 폐석 등을 제거한 원광미분을 자원으로서 활용하는 것이 아니라 열처리 선광방식을 통하여 황 및 비소 등의 환경오염물질이 제거된 원광미분을 자원으로서 활용하는 것이기 때문에 원광미분의 가공 과정에서 발생될 수 있는 환경오염을 원천적으로 차단하는 효과가 있다.According to the present invention, the raw ore fines from which environmental pollutants such as arsenic and arsenic are removed through the heat treatment beneficiation method are used as resources, rather than simply using the raw ore fines from which waste stones are removed after crushing the ore finely. There is an effect that blocks the source of environmental pollution that may occur during the processing of fine powder.
또한, 가열을 통하여 불순물이 제거되었기 때문에 자성에 대한 원광미분의 반응성이 향상되고, 이로 인해 미량의 금속클러스터(원광 또는 원광미분에 포함된 금속덩어리)를 포함한 원광미분의 경우에도 자력을 통하여 검출이 가능한 효과가 있으며, 이를 통하여 금속클러스터와 같은 자성물질을 포함하고 있는 원광미분이 버려지는 것을 방지하는 효과가 있다.In addition, since the impurities are removed by heating, the reactivity of the ore fine powder to the magnet is improved, and thus, even in the case of the ore fine powder containing a small amount of metal clusters (the ore or the mass of the metal contained in the ore fine powder), the detection can be performed by the magnetic force. There is a possible effect, thereby preventing the raw ore powder containing magnetic materials such as metal clusters from being discarded.
그리고 자성이 없는 물질만을 모아서 비중 차이를 이용하여 금 및 은을 검출하기 때문에, 검출에 따른 비용이 절감되는 효과가 있으며 금속성분이 거의 없는 금 및 은의 원광미분을 검출할 수 있는 효과가 있다.In addition, since gold and silver are detected using only the difference in specific gravity by collecting only non-magnetic materials, the cost of the detection is reduced, and the raw powders of gold and silver having almost no metal components can be detected.
또한, 자성 및 비중을 이용하여 검출된 원광미분 이외의 부산물은 건축자재 및 시멘트 등의 재료로 사용되기 때문에 별도의 폐기물 처리비용의 발생을 방지하고 원광을 효율적으로 사용하는 경제적인 효과가 있다.In addition, since by-products other than the ore fine powder detected using magnetic and specific gravity are used as materials for building materials and cement, it is economical to prevent the occurrence of separate waste disposal costs and to efficiently use ore.
아울러 원광미분에 포함되어 있는 환경오염물질을 단순히 제거하는 것이 아니라 별도의 기체처리부를 통해 처리하기 때문에 환경오염물질을 자원으로서 재활용하는 경제적인 효과가 있다.In addition, there is an economical effect of recycling environmental pollutants as a resource because the environmental pollutants contained in the raw ore powder are not simply removed but processed through a separate gas treatment unit.
한편, 별도의 시약 또는 첨가제를 사용하지 않고 간단한 열처리 선광 방식으로 원광미분을 가공하기 때문에 소규모 채굴업자도 손쉽게 원광미분을 가공할 수 있는 효과가 있다.On the other hand, since the raw ore powder is processed by a simple heat treatment beneficiation method without using a separate reagent or additive, even a small-scale miner can easily process the raw ore powder.
