With energy costs increasing and ore grades diminishing, the role of preconcentration in hard rock mining operations has been gaining greater interest. To maximize energy conservation, the pre concentration process should be conducted at as coarse a crush size as possible while minimizing losses of pay metals. Dense medium separation (DMS) is a robust process that can be conducted at ...
