It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.The device has the following characteristics:
1.Wide application field: the device can regenate various types of activated carbonon by adjusting the angle and rotational speed of furnace pipe.
2.Regeneration activated carbon in the oven retention time 40 minutes, which is applicable to the regeneration levelofall kinds of grain particles, for coal activated carbon also has good regeneration effect.
3.High degree of automation:the device operation achieves automatic control,with man-machine interface+Intelligent instrument control,reduces the operating workers and the labor intensity is low.
4.High recovery rate of Iodine value:basically returned to a new carbon levels above 90%.
5.Low carbon loss:≤1-2%(Coal carbon)But slightly higher than the JHR-O series activated carbon fuel diesel reclamation equipment
6.Easy installation, covers an area slightly larger, but the small space height requirements, large installed power.
Long service life:The core components furnace tube using thick wall (10 mm thick) 1200 ℃ high temperature resistance, corrosion resistant special stainless steel pipe.
