Tailings Pond Construction, Xinhai Mining Opens a New Chapter of Excellence

Tailings ponds are storage places for tailings or other industrial waste discharged during the mineral processing of mines. They are usually surrounded by dams and are used to store tailings from metal or non-metal mines. Tailings ponds typically include systems such as tailings storage, flood discharge, and backwater management. Based on the terrain, they can be divided into valley-type, mountainside-type, flat-land-type, and river-interception-type tailings ponds. As a key facility in mine processing plants, tailings ponds not only help to recover resources, but are also important environmental protection projects for mining enterprises, helping prevent untreated tailings from being discharged into the natural environment.
