마그네슘의 제련 및 리사이클링 기술 현황 = Current Status of Magnesium Smelting and Recycling Technology

국문 초록 (Abstract)

마그네슘은 구조용 금속 중 알루미늄과 철에 이어 세 번째로 풍부한 금속이다. 또 마그네슘은 범용 금속 중 가장 가벼운 금속으로, 밀도가 알루미늄보다 33 %, 철보다 77 % 낮다. 마그네슘 1차 지금을 생산하기 위해서는 다량의 에너지를 소비하지만, 마그네슘 스크랩을리사이클링하면 1차 지금 생산과 비교하여 에너지 및 환경부하를 저감할 수 있다. 그러나 마그네슘 스크랩 중의 불순물 제거가 곤란하여재생되는 양은 한정되어 있다. 본 논문에서는 마그네슘의 1차 지금 생산 및 리사이클링 공정에 대하여 고찰하였다.

다국어 초록 (Multilingual Abstract)

Magnesium is the third most abundant structural metal after aluminum and iron. Magnesium is the lightest metal in the common metals. It has a density 33 % less than aluminum and 77% lower than steel. However, the primary magnesium production process is highly energy intensive. The recycling of magnesium scrap reduces the energy consumption and environmental burden, comparing to the primary metal production. However, the amount of recovered metal from scrap is limited because of the difficulties to remove the impurities in the scrap. This work provides an overview of the magnesium production and recycling process.
