Rare Metal by Urban Mining
- Melting Furnace Started Operation for Recycled Materials -

DOWA Metals and Mining, located in Kosaka, the birthplace of DOWA, is engaged as the core industry in the production of base metals including copper, lead and zinc, precious and rare metals that contribute to society as a whole. Leveraging our technologies long esteemed and developed in our history, we are now actively processing raw materials including electronic substrates from PCs and cell phones that are referred to as “urban mining”, in addition to imported ores. We contribute to resource-recycling society through production of recycled metals in response to the growing scarcity of natural resources.

Last year Kosaka Smelting and Refining started commercial operation of its new melting furnace for recycled materials. This new furnace processes a range of recycled materials, refractory materials, intermediate products produced by smelting, mineral concentrates containing high rate of gold and silver, contributing to effective recycling of valuable metals and reduction of wastes, and to further our resource-recycling society. In our life style, many electronic parts are used for PCs and cell phones and thus there are many valuable metals and rare metals found in used PCs and cell phones. We contribute to a resource-recycling society by aggressively collecting resources from such “urban mining” sources.

We also strengthened partnership with Akita Smelting and Refining and Kosaka Smelting and Refining, two largest zinc production bases in Japan to build the world’s top smelting and refining complex to flexibly respond to recycling needs. We try to make use of other used products that used to be difficult to collect and process before. As such, we are committed to play a vital role in our resource-recycling society, by collecting rare metals from used products and supplying recycled materials back to society.
