Abstract

Nippon Mining & Metals company (NMM) carries out its metal recycling and industrial waste treatment businesses employing advanced separation, extraction and refining technologies developed through its extensive experience in the smelting of non-ferrous metals. It collects approximately 100,000 t/y of copper and precious metal scraps from waste sources such as electronic parts, mobile phones, catalytic converters, print circuit boards and gold plated parts. These items are recycled through the smelting and refining operations of Saganoseki smelter and Hitachi plant of the NMM affiliate NIKKO Smelting Company. In addition, environmental services are provided through four other affiliates: Nikko Environmental Service, Tomakomai Chemical, Nikko Mikkaichi Recycle and Nikko Tsuruga Recycle. The purpose of this paper is to provide an introduction to the recycling and environmental service operations of Nippon Mining and Metals group.
