Learn MoreGravity separation dates back to at least 3000 BC when It isGravity Separation Method For OresGravity Separation Method For Ores Sep 12 2022 · Gravity Separation Process In this method the powdered ore is placed on a sloping platform and a jet of water is allowed to flow over it The lighter sandy particles impurities are washed away and the denser settles in the groove
Learn MoreNormally the mass yield to sink is higher using gravity compared with dense media, however if the ore is amenable, it offers a very efficient 'capital and operating' cost option. We often find that 'massive sulphide' style deposits can liberate at very coarse crush sizes (3-15mm) and so pre-concentration prior to grinding may be an attractive option, especially if there is high dilution or
Learn Moreore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG ) and most gangue minerals (SG 2 to 3). For gold ores that are amenable to gravity separation, recovery of the coarse,
