Abstract

This article aims to summarize the scrap recycling status of gold, silver, platinum and palladium from foreign countries by courntires and industries in order to utilize the data for securing the raw materials of the domestic urbanmining industry. The amount of gold from scrap has shown a tendency to decrease in countries other than China, which is attributed to the large imports of scrap containing gold in China. The industry demand for gold is the highest in electronic products, but demand is decreasing. The amount of scrap recycling in silver has declined in other regions compared to those in Europe, indicating that the world's overall scrap recycling volume has declined. Production and demand from scrap of platinum and palladium are mostly for catalysts and have been steadily increasing until now. However, it is expected that the amount of waste catalysts in automobiles will decrease with the increase of electric vehicle use.

이 글은 해외에서 발생하는 금, 은, 백금과 팔라듐의 스크랩 재활용 현황을 국가 또는 지역별 생산량과 금속의 산업별 수요로 정리하여 국내 도시광산산업의 원료 확보를 위한 데이터로 활용하고자 하였다. 스크랩으로부터 발생하는 금의 양은 중국을 제외한 국가들에서 감소하는 경향을 나타냈으며, 이는 중국으로 금이 함유된 스크랩이 다량으로 수입되어 처리된 것이 원인으로 생각된다. 금의 산업수요는 전자제품에서 가장 높으나 수요량은 감소하는 것으로 나타났다. 은의 스크랩 재활용양은 유럽지역의 국가들에서 비교적 일정한 것에 비해 다른 지역 국가에서 감소하는 것으로 나타나 세계의 전체적인 스크랩 재활용양은 감소한 것으로 나타났다. 백금과 팔라듐의 스크랩으로부터의 생산량과 수요량은 대부분 촉매에 기인하며, 현재까지 지속적으로 증가해왔으나 전기자동차 사용의 증가와 함께 향후 자동차 폐촉매 발생량은 감소할 것으로 생각된다.
