The Recycling of Precious Metals at Yokohama Metal Co., Ltd.

Development of a new technology for recycling of precious metals from waste materials

Abstract

Since the amount of natural resources is decreasing year by year, the recycling of precious metals from waste materials, coming from industrial plants, hospitals, or private consumers, should be carried out in order to save resources and protect the environment. Nevertheless, the structure of such waste materials is becoming complicated year by year. In turn, new processing technologies should be developed to treat such waste materials for recovering valuable products.
Within this frame, the aim of this paper is to introduce the current status on how the recovery of various metals from waste materials is being carried out at Yokohama Metal Co., Ltd., the company specialized on recycling of precious metals.
