Near the western shore of Sado Island you will find one of Japan’s most impressive industrial heritage sites - The ruins of the Kitazawa flotation plant. Built during the first half of the 1900s, this was once the biggest producers of ore in East Asia.\nA flotation plant is a site where the final stages of gold mining takes place. More precisely, it’s where the valuable minerals that get extracted from the mine are separated from all the other things that get dug out, such as waste materials and other bi-products. The flotation process requires vast areas of land as well as huge amounts of energy. As the gold mine of Sado used to be the biggest in the entire East Asian region, it shouldn’t come as a surprise that the flotation plant is a huge structure. Several new techniques that led to a more efficient ore extraction process were also pioneered here.
