milling and flotation circuit for gold

approximate the expected recovery of free gold in a flash flotation cell. The gravity/flash flotation relationship for GRG When both gravity concentration and flash flotation are employed in a milling circuit, flash flotation can be used in parallel, series, or cleaning arrangements with BCC units, as seen in Figure 2

    Stabilising the product quality from the milling circuit leads to improved recovery downstream. In the case of flotation processes, improvements of between 0.5 and 1.5% in recovery have been shown. On gold leaching circuits, MillStar will minimise grind size while still maintaining throughput targets. This leads to considerable

    Among free-milling gold ores placer gold is a special case, as there is no pre-treatment required for gold extraction. ... The most economical approach for sulphide ores is to utilize a gold-copper flotation circuit which uses smelting for gold recovery. The main consideration for this route is that the float tail can contain too much gold
