Mercury Ore Beneficiation Process

Mercury Ore Processing

The concentration of low grade cinnabar, HgS, with a specific gravity of 8.0-8.2 is effectively accomplished by gravity and flotation methods. Cinnabar ores of relatively high mercury content can be retorted directly to expel the sulphur and condense metallic mercury, but for lower grade ores, preliminary concentration is advisable to reduce the tonnage for retorting. … Read more
