GOLD ORE GRAVITY CONCENTRATION

Elemental gold has a specific gravity of 19.3, and typical ore has a specific gravity of about 2.6. All gravity concentration devices create movement between the gold and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material. The prospector's gold pan is the most familiar gravity concentration device.

Ask MGS: What are Gold Concentrates?

Gold concentrates tend to be mostly iron, so they are also known as "black sands.". Gold concentrates are also made by grinding down ore, quartz, or other productive rock types into sand. This procedure is much faster and easier than panning, but the tradeoff is a final product that has less gold "concentrated" within.

Pre concentration and pressure oxidation of Porgera refractory gold ore

The complex mineralogy of the Porgera resource has a pronounced effect on process selection for the recovery of refractory gold and silver. Intimate association of gold with pyrite necessitates a high degree of sulphur preoxidation to achieve acceptable levels of gold recovery. Acid pressure oxidation has been demonstrated to be the only …

Concentration of Ores

Explanation: Concentration by hydraulic washing requires the ore particles to have a higher mass compared to its gangue particles. Hydraulic washing can be used for oxide ores of iron and tin such as haematite and tinstone and also for native ores of silver and gold. Pyrolusite is concentrated by magnetic separation.
