Kitazawa Flotation Plant Ruins
In Japanese: 北沢浮遊選鉱場跡

Ruins of the ore-dressing plant that helped modernise the Sado gold and silver mines. It was the first in Japan to apply flotation to gold and silver, handling up to 50,000 t of ore a month and earning the name "best in the East". Massive concrete foundations remain.
