광미(鑛尾, tailing)는 광산에서 채광된 광석을 모래와 같이 미세하게 분해하여 비중을 이용한 비중선광법 등을 통하여 추출 후 남은 광산 폐기물로서 비소, 황, 카드뮴 등의 성분을 포함하고 있어 주변의 하천 및 토양을 오염시키는 오염물질로 인식되고 있다. 특히, 비소는 살충제 등에 사용되는 물질로서 피부에 닿으면 피부가 헐거나 염증이 생기며 일정량 이상 섭취할 경우 생명이 위태로울 수도 있으며, 황은 빗물 또는 지하수를 산성으로 바꾸어 광미에 포함되어 있는 중금속을 용출시켜 주변의 하천 및 토양을 심각하게 오염시킨다. The tailings are mine wastes left after extraction through the specific gravity mining method using specific gravity after finely decomposing ore mined in the mine like sand and contains components such as arsenic, sulfur and cadmium. It is recognized as a pollutant that pollutes rivers and soils. In particular, arsenic is a substance used in insecticides, etc. When the skin touches, the skin may break down or become inflamed.If it is ingested over a certain amount, it may endanger life. Seriously contaminates rivers and soils.

그런데 광미에는 환경오염물질 뿐만 아니라 금속들(금, 은, 철 등의 희귀금속)이 결합된 금속클러스터를 포함하고 있어 자원적 가치로서도 활용될 수 있다.The tailings, however, contain metal clusters combined with metals (rare metals such as gold, silver and iron) as well as environmental pollutants, which can be used as resource values.

그리하여 광미에 포함되어 있는 환경오염물질을 제거하고 자원을 재활용하는 선행기술로는 대한민국 등록특허10-0318754호(발명의 명칭: 금광선광폐기물로부터 건식방법에 의한 유가광물의 분리회수방법) 등이 있다.Thus, as a prior art for removing environmental pollutants contained in the tailings and recycling resources, there is a Korean Patent No. 10-0318754 (name of the invention: a method for separating and recovering valuable minerals by dry method from gold mining wastes). .

하지만 상기 인용기술은 광미를 재활용함에 있어 습식공정이 아닌 건식공정을 사용하여 습식공정으로 인해 환경오염물질이 방류되는 것을 예방하는 기술만을 개시하고 있을 뿐, 근본적으로 광미에 포함되어 있는 환경오염물질 및 자원을 분리하지 못하는 문제가 있다.However, the above-mentioned cited technology discloses only the technology for preventing the discharge of environmental pollutants due to the wet process by using a dry process rather than a wet process in recycling the tailings, and essentially the environmental pollutants contained in the tailings and There is a problem of not separating resources.

Rare metals such as silver and iron can be prevented from being recycled and discarded.

또한, 광산폐기물인 광미에 환경오염물질을 단순히 제거하는 것이 아니라 별도의 포집부를 통해 포집하기 때문에 환경오염물질을 자원으로서 재활용하는 경제적인 효과가 있다.In addition, there is an economical effect of recycling environmental pollutants as a resource because it is collected through a separate collector rather than simply removing the environmental pollutants in the mine tailings.
