Kitazawa Flotation Plant

A symbolic modern heritage: the greatest flotation plant in the East

The Kitazawa area in Aikawa is home to a group of facilities, such as a power plant and a thickener (designated National Historical Site), which contributed to the modernization of mines. The flotation method had originally been used for copper beneficiation, but at Kitazawa Flotation Plant, the technniques were applied to silver and gold extraction, and successfully utilized for the first time in the world. Under a war-time increase in production plan, large-scale investment was made. As a result, the Flotation Plant was able to process over 50,000 tonnes of ore per month, and the plant was declared the greatest one in the East.
