Primary gold generally occurs as free grains, on sulphide boundaries and to a minor degree with silica grains. The RoM ore particles to feed SAG mills (Samples A and D) were crushed and screened to obtain the required size fractions (as detailed in Section 3.2) for high voltage pulse treatment. The pebbles (Samples B and C) were screened ...

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 …

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.
