HOW TO CHOOSE THE RIGHT SEPARATOR FOR YOUR PLACER GOLD MINE?
Gravity separation is generally used as placer gold rough enrichment with gold jigging separator, chute mainly involved. As the ideal gold separator, there are many kinds of jiggers with different capacities. But how to choose the most suitable model for a gold mine, please? Here is some share about jigging separator for alluvial gold ore.
In the jigging market, there are many jig machines for fine grain size while few companies have jiggers for coarse granules upgrading. For gold, especially alluvial gold ore, the common diaphragm jig separators for fine grains can work well with great enrichment efficiency. Jiggers like AM30 & 2LTC912/4A are mainly for coarse granules and not suitable for placer gold ore extraction.
The down-driven jig, saw tooth wave jigger, trapezoidal jigging machine are all fine grain jig separators, and they are all suitable for beneficiating of alluvial gold. However, for gold of different shapes, different gold jig shall be used accordingly. For coarse granule gold ore, all three kinds of jiggers can work well. But for gold of fine pieces saw tooth wave jig machine can help to get the best beneficiation efficiency. The special structure and pulsation curve makes an ideal enrichment efficiency for piece gold and other irregular gold, so for this kind of gold mine, saw tooth wave jiggers are mainly involved with its high recovery rate and good beneficiation efficiency.
For some gold mine of low Au content, a large treatment capacity is needed to guarantee the ideal profit, and here trapezoidal jig separator can be considered. There are eight jigging chambers on this machine and its working section is trapezoidal with gradual change from narrow to wide. This gold jig gravity separator can help to get good beneficiation efficiency with its large treatment capacity and high recovery rate.
Jigger is widely adopted for many gold mines as high-efficient separator. And about how to choose the right type of jigger, here Forui can supply a small test. If samples about 15 kgs can be available, a small test can be done free, and a detailed flow sheet can be designed accordingly.
