Gold Flotation Mineral Processing & Metallurgy

2020-05-15· It is a good practice to recover as much of the gold and silver as possible in the grinding circuit by amalgamation, corduroy strakes, or other gravity means to prevent their accumulation in the classifier; otherwise gold that is too coarse to float may escape from the grinding section into the flotation circuit

Flotation of Gold and Gold-Bearing Ores ScienceDirect

7. Flotation of Gold and Gold-Bearing Minerals 7.1. Differential Flotation of Natural and Liberated Gold. Experience has shown that free gold particles can be recovered selectively against pyrite, by keeping the gold particle surfaces as clean as possible of organic species and by removing any adhering slime particles (Klimpel, 1997).

Sulphide Flotation an overview ScienceDirect Topics

Concentrators that have this circuit configuration have found that most of the fine gold is recovered in the flash flotation circuit, leaving the gravity circuit to recover the coarser gold. One of the dilemmas arising from laboratory testing for the combined circuit is that the standard gravity test procedure will overpredict plant gravity recovery, because fine free gold is captured in the
