Abstract

This paper introduces several waste material processing by means of fine grinding followed by chemical and/or physical operation or reaction: The first example consists of grinding the dust produced in a power station using a heavy oil as a fuel, following water rinsing to extract V from the electric precipitation (EP) dust. The second is to extract indium (In) from ITO scrap produced by a sand-blasting using Al2O3 powder, followed by grinding by a planetary mill in air. The third is to extract rare earths (Y, Eu, La, Ce and Tb) from fluorescent lamp wastes which contain Y, Eu, La, Ce and Tb-compounds. Leaching the fluorescent powder using 1N HCl solution at room temperature after grinding of the powder in air using a planetary ball mill was conducted. The fourth example is to dechlorinate polyvinyl-chloride (PVC) and defluorination of PVDF. The final example is to recover the energy in biomass in form of hydrogen by solid-state reaction of cellulose with hydroxide additives with aid of MC treatment.

본 논문에서는 물리적, 화학적 공정 및 반응을 수반하는 미분쇄공정에 대해, 몇 가지 폐자원을 처리, 유용물질을 회수 예를 통하여 설명하고자 한다. 첫 번째로는 발전소에서 발생하는 EP 더스트로부터 바나듐 추출에 대한 분쇄공정을 설명하였고, 두 번째 예로는 알루니마 분말에 의해 샌드블라스트공정 중에 발생하는 ITO 스크랩으로부터 인듐의 회수, 세 번째는 폐형광등으로부터 상온조건 하에서 희토류 원소를 추출하기위한 분쇄효과에 대해서 설명하였다. 네 번째 예에서는 할로겐유기화합물로부터 할로겐원소만은 제거하는데 응용되는 분쇄반응에 대해 언급하였고, 마지막으로는 수산화물과 셀룰로오스와의 분쇄공정에서 발생하는 고상반응으로 에너지원인 수소성분을 회수하는 연구에 대한 설명을 게재하였다.
