Gold Extraction Process Methods Summary - JXSC Machine

However, for rock gold beneficiation, the gravity separation process is rarely used as a part of the gold extraction process. Generally, in the grinding and grading circuit, the jig and the spiral chute are combined with the shaker to recover the coarse gold in advance, which is preparation for subsequent flotation and cyanidation process and to obtain a qualified gold

Gold Extraction Recovery Processes

Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 m/s., and decreasing the feed size by performing a previous screening.
