Applicability of gold tailings, waste limestone, red mud
Dec 01, 2018 · During gold processing, huge amounts of byproducts called gold tailing are generated and abandoned near mining sites. The goldcontaining ore is found in sulfide form and mineralization of gold tailings causes environmental contamination by releasing acidic effluents and leaching of cyanide complexes (Ritcey, 2005). During the Bayer process
