Gold Recovery From Tailings

Turning tailings into gold

· New Carolin Gold of Vancouver has completed a preliminary economic assessment for tailings reclamation at the former Ladner mine north of Hope, BC. The study recommends that a portable, 400t/d mill be used to produce a saleable concentrate from the old tailings. The mill would operate seasonally over five years, producing 24,483 oz of gold in concentrate.

What Are Tailings?

Gravity separation is used in gold processing to recover the coarser particles, the finer being recovered by leaching (EC 2004). Refractory ores are commonly processed using pressure oxidation, bioleaching and roasting prior to leaching techniques. These types of preprocessing are often associated with ultra fine grinding that generates tailings with slow settling and low insitu density ...

Value recovery from mine calcine tailings

The possibility of recovering gold from a calcine tailings heap was considered in this study. Due to the refractory nature of the host ore from which they were generated, a mineralogical characterization was performed to understand the nature and occurrence of the gold. Fire assay revealed a gold grade of ± g/t. Xray diffraction (XRD) and quantitative evaluation of minerals by ...
