4. CONCLUSION The mineralogical analysis of the Mastra gold ore has shown that gold occurs as associated with quartz and sulphide minerals, and as particles of 1-300 μm in size. The gold particles, having a size of ≥150 μm, were estimated to be 50% of the gold present in the ore, indicating its potential for gravity recovery.

Flotation concentration is not effective on coarse gold. The small miners who wish to treat a small tonnage of high grade ore and want a quick return rather than for recoveries near to , probably still find the amalgamation process the best available recovery method. The final product grade depends on the gold ore treated.

The gold-bearing ore was heated as a thick slurry of ore, air, water and limestone in large pressure chambers. The slurry interacted with thiosulfate and a fine, bead-like material that collects the gold. At full capacity, 13,400 tons of ore can be processed daily, with leaching taking place simultaneously in two sets of seven tanks.
