Difficult to select rare earth mineral recovery technology

For the primary ore of fluorocarbon persimmon or monazite, the industrial grade index generally requires Ce 2 O 3 >1%; for monazite ore, the content of monazite mineral is greater than 300g/m 3 . Fluorocarbon persimmon mines are mainly recovered by flotation; monazite is usually recycled by re-election, magnetic separation, and electric separation, and flotation is used in individual stages of the process. Xenotime is selected from titanium, zirconium byproduct minerals, usually reselection, electrostatic separation, high intensity magnetic separation joint process sorting, but this method is not applicable to fines. In recent years, the process of recovering antimony concentrate by flotation has attracted attention. Ion-adsorbed rare earth ores are adsorbed in clay minerals such as kaolinite, halloysite, quartz , montmorillonite and illite. The ion-adsorbed rare earth ore does not need to be broken, and the rare earth oxide is recovered by a chemical beneficiation method. In the 1970s, the production process was infiltration of salt water - oxalic acid to precipitate rare earth, and the mother liquor was recycled after treatment with caustic soda. In the early 1980s, the infiltration facility was improved and the mother liquor recovery was changed to lime milk neutralization and regeneration. Ammonium sulfate solution infiltration - oxalic acid precipitation rare earth - burning process is a major production process.

Pneumatic Connector

Pneumatic quick connector is a kind of quick connector which is mainly used for air piping and pneumatic tools. It can connect or disconnect the pipeline without tools. When the connector is not connected - when the parent's ferrule moves to the other end, the stainless steel ball will automatically roll outward, and the daughter will be disconnected under the action of the common valve spring force of the parent and the daughter, and the daughter and the parent's valves will be closed respectively, The fluid flow is blocked instantaneously.

Purpose and features editing voice

The quick connector is suitable for the connection of pneumatic pipeline, compressed air and nitrogen, and the working position where the pipeline can be loaded and unloaded frequently, such as the operation of pneumatic tools in the assembly line. It can also be used in hydraulic machinery, chemistry, ship piping, etc.

Scope of application editing voice

Air pipe, air compressor, grinder, air drill, impact plate hand, air transport screwdriver and other pneumatic tools for quick connection.

Note edit voice

1. Please do not use it for any purpose other than quick fluid connector.

2. Please don't use it for other fluids.

3. Please do not connect with the quick fluid connector made by other company.

4. Do not exceed the maximum pressure when using.

5. Do not use outside the temperature range to prevent the sealing material from wearing or leaking.

6. Do not hit, bend or stretch artificially to prevent damage.

7. Do not use it in places mixed with metal powder or sand dust to prevent poor work or leakage.

8. If foreign matters are attached, it will cause poor work or leakage.

9. Do not remove the quick coupling.
