The present invention is a method for extracting gold from gold-containing mass. In the invention, the activated carbon fiber is contacted with various concentrations of the gold-containing solution to adsorb gold, and after contacting for a period of time, the adsorbent material is separated from the solution, and after burning, gold is obtained.
The method of the invention is simple, the equipment used is small, the scope of application is wide, and the economic benefit is remarkable.
Inventor: Zeng Hanmin, etc.
Concrete Pile Pre-stressed/Tension Machine:
Tension Machine is a kind of feedthrough pre-tensioing. It is also called Spun Pile tension jack machine, Pole Tension Machine, prestressed tension machine etc. It is the neccesary equipment to produce Pre-stressed Concrete Spun Pile and prestressed concrete pole products. As the end of the tension rod is connected to the anchor with thread, it can be applied to various forged anchors, chilled iron anchor used for stayed-cable bridge and other similar anchors, as well as pre-tension pulling for pipes. In accordance with actual requirement.
HH Tension Machine's advantages:
1. The large-screen LCD display.
2. Double control mechanism of touch screen and keyboard, high reliability.
3. Directly work after the input of tensioning data, and the oil cylinder will automatically complete the tensioning process to reduce uncertain factor of manual operations and improve the tensile quality.
4. Built-in SD card function, which can save the tensile data to the computer regularly, and check the record at any time.
5. With its own printer, it can print tensile data in working time, avoiding the tedious and unstable manual record and ensuring the traceability of tensegrity data is verified.
Technical Parameter:
1. Oil pump flow: 12L/min
2. Motor power: 7.5kw
3. Rated power: 31.5Kpa
4.Tension force: 2000KN
5. Tension stroke: 200mm
6. Programmable controller of automatic control system + input and output of analog data Color touch screen, USB interface output
7. Control voltage: 380V+24V
8. Accuracy of prestress control:±0.1Mpa
9. Data transmission rate is 100%
Main configuration:
Automatic tension control system, 300T jack, oil pump, lifting trolley, tensioning rod, tensioning head and supporting foot.
