Assessing The Acid Mine Drainage Potential of A Stockpiled Gold Bearing Sulphide Ore.
This work seeks to assess the acid mine drainage (AMD) potential of stockpiled sulphidic gold bearing ore that was left untreated for a period of four (4) years. The mineralogical composition of the stockpiled sulphidic gold ore was determined using X-Ray Diffractometry (XRD) and Reflected Light Mic...

| description | This work seeks to assess the acid mine drainage (AMD) potential of stockpiled sulphidic gold bearing ore that
was left untreated for a period of four (4) years. The mineralogical composition of the stockpiled sulphidic
gold ore was determined using X-Ray Diffractometry (XRD) and Reflected Light Microscope. The AMD
potential and kinetic studies on the ore sample were determined using Acid Base Accounting (ABA) and
Humidity Cell (ASTMD 5744). The XRD and microscope analyses showed that the gold ore contain
arsenopyrite and pyrite as the major sulphide minerals. The ABA confirmed that the gold sulphide ore could
be a potential source of AMD with respect to AMD marginal of safety if the ore is left untreated for a very long
period. Humidity Cell kinetic analysis showed a possibility of mobilizing Arsenic (As) into the geoenvironment
when there is a long period of oxidation of abandoned sulphide run-of-mine (ROM) ore. |
