Gravitational Gold Concentrator
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.

Some scandals about Uber drivers have been exposed during the past few months. For example, drivers and passengers are in conflict, and drivers are sexually harassed by female passengers. After several months of research and public relations work, Uber announced a new policy yesterday: Uber users need to pay an additional $1 “security fee†every time they use the app to get a taxi.
Starting today, when users open Uber, they will see this message: "In order to provide you with the safest ride service, we will charge you an additional charge of $1."
It is reported that in addition to Uber, their most important competitor, Lyft, has formulated a similar policy.
Uber said that the fees they collect will be used to investigate the driver’s background, carry out routine vehicle inspections, provide safety education for drivers, and develop current and future safety features and insurance.
The company said in a statement yesterday: "They will continue to work hard to ensure the safety of passengers." Uber began to charge "security fees" and users will respond, we can only wait for feedback from users in the next few days. It is foreseeable that this policy will certainly reduce the user’s enthusiasm for this service more or less. After all, people who choose Uber go for "low prices".
