Abstract

The demand for platinum group metals for various advanced industries has been growing due to their excellent physical and chemical properties. Since the deposit of platinum minerals are restricted to few countries, their recovery from various secondary resources has becomes an important issue to related industries for keeping the supply reliably. In this paper, patents on the metallurgical technologies for the platinum group metals were analyzed. The search of patent was limited to the open patents of USA (US), European Union (EP), Japan (IP), and Korea (KR) from 1986 to 2006. Patents were surveyed using key-words searching and selected by filtering criteria. The trend of patents was analyzed by the years, countries, companies, and technologies.

다양한 고도 산업계에서 사용되는 백금족의 수요는 그들의 특별한 물리화학적 특성으로 인해 날로 성장하고 있다. 광물자원이 몇몇 나라에만 한정되어 있기 때문에 다양한 이차자원으로부터 백금족 금속을 회수하는 것은 신뢰성 있는 공급의 지속성에 대해 연관된 산업체에서 매우 중요한 이슈로 부각되고 있다. 이 논문에서는 백금족 금속의 화학야금기술에 대한 특허를 분석하였다. 검색의 범위는 1986년부터 2006년까지의 미국, 유럽, 일본 및 한국의 공개특허로 한정하였다. 특허는 주제어 검색, 분류기준에 따른 선별법을 이용하여 분류하였다. 백금족금속 특허의 경향을 연도별, 나라별, 회사별 및 기술별로 분류를 하여 분석하였다.
