reclamation of specifically, the ownerless mine dump material. 2. MATERIALS AND METHODS . Sample preparation . The gold tailings samples for the test work were sourced from various mining locations in SouthAfrica as shown in Table 1. The samples were analysedindividually in order to evaluate variability in chemical and metallurgical response.
The reclamation project was preceded by 80 years of environmental impacts from the milling operation and discharges from the tailings impoundment (fig. 1). In 2015, NPS and Montana DEQ scientists initiated longitudinal studies of water quality in Soda Butte Creek to document water quality downstream of the reclaimed tailings site and during the ...
Gold Extraction from Tailings. Star Trace has been providing a standard technique for extracting the mineral contents from the mining tailings. Star Trace will start the process by sample testing through the mineral content of the tailings.
