13.5 Mineral Processing – Batch Tests
13.5.1 Variability Tests
Granulometry and screen tests were performed on ore from Bull Hill and Whitetail
deposits to assess the benefits of upgrading the ore by simple screening. BH oxide
(Ox) ores are more amenable to upgrade by screening than oxide-carbonatite (OxCa)
ores from the same deposit. Neither the BH Ox nor BH OxCa respond well to
magnetic separation, but they do respond to gravity separation.
Whitetail ore responds well to beneficiation techniques where gravity and magnetic
separators are applied in stages on the coarse ore. 3 inch drill core samples were
obtained from BH and WT deposites. Figure 13.1 and 13.2 are maps indicating
multiple sites (central and outlaying zones) where drill core samples were taken in
