Gold placer mineral collect method

Ore (particle size of 2mm) sorting using shaker with gold 120.36g / t of heavy minerals: magnetite 30%, 10% ilmenite, quartz, feldspar, 25%, 7% of the zircon 10% hornblende, monazite 3%, limonite 8%, 2% garnet, mica, tourmaline about 5%. Into the electrostatic separation, the material is divided into two of +70 and -70 mesh.

Electrostatic separation process is relatively simple, with a roughing, a sweeping election. Prove tailings using high-voltage election, enables gold recovery rate of 93.91%, into the gold of the electrostatic separation 387.22g / t, power select +70 mesh and -70 mesh gold concentrate can be enriched to 13480.93g / t , mine is 1147.38g / t, such as then mine further electrostatic separation, gold recoveries can be further improved. Magnetic product with low intensity magnetic separation to separate the magnetite, almost the same process, the crude concentrate of the proceeds of gold 24.13g / t of ore and tailings, excluding gold.

Gold ore beneficiation process

1) ore the first paragraph broken into the double deck vibrating screen sieve, and middle-level products with the second paragraph of the broken upper product by broken, and the second broken return to the merger the first paragraph of broken products sievepoints.

2) screening the final product after the first paragraph of energy-saving ball mill grinding and classification bodies to constitute a closed circuit grinding, its classification the classification of the overflow by the cyclone to enter the second paragraph of the ball mill grinding, and then swirl constitute a closed-circuit grinding.

3 )cyclone overflow first flotation foam products for the second selection, three times the selection of the final concentrate product, flotation tailings after a rough selection, once selected, the second fine election, the three selected sorting process, a scavenger, a selection of tailings with a scavenger foam products together into the cyclone re-grading, re-sorting, the second selection of the first selection constitute a closed-circuit selection, three times the selection and secondary selection of a closed-circuit sorting.

Placer gold vibrating screen

Placer gold vibrating screen Application: The vibrating screen for gold dust filter,advanced structure, the excitation power, low noise, easy to repair durability and other characteristics. Aircraft materials in line with GB, throughput of 100-150 m3 / h.
