This project is used to treat the wastewater of an old copper mine in place of the old treatment method. The wastewater in the Falun copper mine contains various metal sulfates, such as iron, zinc, aluminum, and a small amount of copper, magnesium, cadmium and other metals.

Copper is removed following a new process, in which recycling some components in the wastewater is taken into consideration to reduce the waste of resources. Also, the new process can handle the wastewater discharged by surrounding areas. It basically doesn't produce wastes except some filter cakes and solid wastes containing cadmium with the total amount less than 1% of previous process. The metal components in the wastewater can be recycled except cadmium, so as to produce great economic value.
