귀금속 함유 물질과 반응물은 고온과 고압이 유지되는 반응 구역에 장입되어 귀금속 이온 용액을 함유하는 슬러리를 형성하게 된다. 귀금속 이온 용액이 슬러리로부터 분리되고 귀금속 회수 방법을 거치어 귀금속이 회수된다.Precious metal-containing materials and reactants are charged into a reaction zone where high temperature and high pressure are maintained to form a slurry containing a noble metal ion solution. The precious metal ion solution is separated from the slurry and the precious metal is recovered by the precious metal recovery method.
