China has done a lot of experimental research on the new process of leaching-extraction-electrowinning method to recover copper , and has achieved certain results. For example, a lot of experimental research work has been done on the new process of copper, and some achievements have been made. Copper Mountain copper for example, record iron ore tailings disposal, the application of this new technology recovery test a lot of research work on the flotation tailings of copper oxide, copper, semi-industrial pilot plant established on the basis of small-scale experiments, test The process is as shown below. Tests have shown that the use of acid leaching-extraction-electrowinning to recover copper from copper oxide ore flotation tailings is technically feasible. The tailings are leached by sulfuric acid. The copper grade of the tailings is reduced from 0.88 to 1.095% to about 0.3%. The leaching rate of copper can reach more than 65%. The extracting solution is extracted by copper extraction, and the extraction rate can reach 96~98%. The copper-rich solution obtained by back-extraction can be directly electrowinned to obtain an electric copper product having a purity of 99.95%.
Bulk Cement Truck, also known as powder material carrier, by a special purpose vehicle chassis, bulk cement vehicle tanks, tracheal road system, automatic discharging device and other parts. Suitable for fly ash, cement, lime powder, mineral powder and granular base grain diameter is not more than 0.1 mm powder dry bulk transport of materials. Mainly used for cement, cement warehouse and large construction sites, can save a lot of packaging materials and loading and unloading work.

Bulk cement truck chassis
Can choose dongfeng chassis, chassis, fukuda chassis of liberation and steyr heavy vehicle chassis, jianghuai chassis.
Bulk cement tank car
Bulk cement tank car is mainly composed of cylinder, the top of tank for inlet, fluidized bed, discharge tube assembly, of intake pipe and other accessories.
At the top of tank is equipped with two or three mouth to feed
CLW GROUP TRUCK Bulk cement truck tracheal road system
Bulk cement truck front, air chamber after each set an air inlet pipe, can be realized respectively by ball valve at the same time open and separate control.
CLW GROUP TRUCK Bulk cement truck Working principle of the system are as follows: motivation from the car gearbox, through the transmission device drives the air compressor, the compressed air in the gas pipeline interior control, make the tank of powder material produces fluidization phenomenon. When the pressure is 0.196 Mpa, open the discharge butterfly valve, discharge.

1, don't overspeed driving bulk cement truck, overpressure, running speed and overpressure can severely damage the air compressor. This machine is the highest speed main technical parameters see table, work pressure is 0.2 MPa.
2, don't start or stop the air compressor, fast and slow growth or slow down, otherwise, the impact force will damage the compressor.
3, don't change the rotation direction of air compressor, otherwise, the oil pump is not oil can seriously damage the machine.
4, do not stop in front of the reduced pressure air compressor, otherwise, the powder material may go back into the cylinder, air compressor is serious damage.
5, need to check the oil before starting the standard. Oil oil level shall not be lower than the lower limit; Need to check whether the oil pump oil supply, without oil, it is necessary to stop the machine immediately to check, otherwise, oil shortage will seriously damage the air compressor.
6, to timely replacement lubricating oil. Phone use after 30 hours, discharge of oil in the crankcase, clean inside the crankcase and oil screen, and then an oil change. According to the above oil change once a year later.
7, to check, clean oil screen. Normal quarterly inspection, cleaning time, if the machine utilization rate is high, should check and clean once a month.
8, this machine is used for CD40 lubricating oil diesel oil. Ban on different type of lubricating oil to mix, or lubricating oil deterioration will affect the lubrication effect.
9, each working 30 hours to maintain, clean air filter. While rotating filter pressure is less than 0.6 MPa compressed air blowing from inside to outside. Maintenance after five times, please replace the new filter. It is forbidden to oil or water to clean the filter element.

The recovery of copper has a higher acid consumption, power consumption, high cost disadvantages and tailings of silver and gold and other precious metals can not be effectively recovered. Therefore, this process has not been applied to the industry to achieve industrial scale production.
