Smelting and Roasting Ores to recover gold, silver and other metals

When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix. The metal in the nails reacts with the metals in the sulfides reducing the metals to their metallic state. This is handy when processing silver containing minerals to convert them to silver metal. The addition of scrap iron to smelt.

samples indicated that acanthite exhibited natural hydrophobicity. These results, together with the mineralogical characterisation, indicated that selective flotation would be an appropriate processing route for this ore. The coarse grained silver minerals required a P80 of 100 μm and a specific dosage of a mix of collectors.
