As fine gold can be lost to the tailings when the pulp flow speed is high, it is always beneficial to have multiple-stage sluices. As most of the gold is recovered in the first meter of a sluice, a way to increase the gold recovery is by using a zigzag arrangement. In this case, the velocity of the flow will be,In Demand Of Gold Bars And Gold Ores | TradeKey,11/02/2021· Attention: If your gold bars are not exact 24 Carat + 99.99% purity, then your gold has to be sent to Hong Kong legal and qualified gold refinery for smelting with both seller representative and buyer representatives presence, then buyer party will settle the full payment to seller party on the basis of the final weight of exact 24 Carat and 99.99% purity gold after smelting and assay report.Pressure Oxidation | SGS,The process is particularly well suited for treating refractory gold ores, which give low recovery when directly leached with cyanide.
