Despite the challenges it faces for large slurry flows, the benefits of water recovery could make this technology very attractive for future tailings disposal projects. This paper presents an economic and strategic comparison between the use of the paste technology and the conventional tailings dams system. Both alternatives are designed for the disposal of 30 years of production of a real plant, considering a processing capacity of more than 100,000 dry tonnes per day.
