Mine Waste Transfer and Disposal Methods
Oftentimes, inefficient processing methods can produce gangue that still holds an ample amount of valuable minerals. As values of minerals increase, it can even be profitable to reprocess gangue to extract additional minerals that may have been missed during the first processing. Mine Tailings

Feasibility of re-processing mine tailings to obtain ...
· 1. Introduction. Mine tailings are waste obtained after the processing of some minerals to acquire one or more elements of interest. They are composed of a mixture of heavy metals, water, sand, and fine-grained solid material, and generally are deposited in ponds without further treatment (Babel et al., 2016; Santibañez et al., 2012; L. Wang et al., 2017).
