Suitable for processing natural gold embedded in coarse particle size, stored in pyrite and other sulfide ores. Different from single flotation is to add mercury plate for gold recovery after grinding, the recovery rate can reach 3045%. After mercury amalgamation, the slurry is flotation through the overflow of the classifier.
