Enhanced gravity separation, wet high-intensity magnetic separation, and flotation have been reported to be successful in reprocessing tungsten tailings, while …
Abstract: Repositories of historical tungsten mining tailings pose environmental risks, but are also ... the amount of valuable minerals in HT depends largely on the initially employed beneficiation methods and their efficiencies. For instance, for high density ores such as scheelite ores, gravity separation ...
Repositories of historical tungsten mining tailings pose environmental risks, but are also potential resources for valuable metals. They still contain large tonnages of useful minerals and metals, reflecting the inefficient extraction methods and/or low metal prices at the time they were mined. The focus of this study is to evaluate the technical …
In terms of mining and beneficiation, there are few studies on soil heavy metal pollution characteristics and health risk assessment of tungsten and molybdenum mining areas (Huang et al. 2014; Zhang et al. 2017).
