  8.2: Mining and Ore Processing - Geosciences LibreTexts

  The tailings pond at the Volcanogenic Massive Sulphide copper-zinc-silver-gold Myra Falls Mine on Vancouver Island is shown on Figure 8.2.3. The tailings are contained by an embankment. Also visible in the foreground of Figure 8.2.3 is a pile of waste rock, which is non-ore rock that was mined in order to access the ore.

  Improved recovery of a low-grade refractory gold ore using …

  201471 · In addition, the bulk flotation method resulted in the concentrate with low concentrations of Sb and As elements. To improve the recovery of low-grade refractory gold ores, flotation should be followed by roasting, biological, or pressure oxidation processes so that the gold could be liberated prior to cyanidation processes.
