Description
Technical field
The present invention relates to a kind of flotation combined desliming process of ultrasonic wave-shaking table-, belong to technical field of mineral processing.
Background technique
The source of sludge is generally divided into two kinds, and one is primary slime, the sludge that ore is formed in mineralizing process is another
Kind is that subsequent exploitation sorts secondary slime of the ore in the process due to polluting or excessively honed pulverized zone is come.Thin mud described in people
Usually material of the granularity less than 10 μm, these fine granule materials have very big surface area, sort in mineral since granularity is small
A large amount of medicament can be consumed in the process, can also be attached to coarse grain mineral surfaces, drastically influence subsequent sorting operation.Therefore, exist
It generally requires to carry out desliming process when carrying out to mineral and sort separation, obtains better separating effect for subsequent sorting operation and provide
Precondition.
For the higher ore containing mud, desliming, such as the higher zinc oxide of clay content are often first carried out before being sorted
Mine will increase foam viscosity when using vulcanization-amine method flotation, foam can be difficult to eliminate, serious race if clay content is too high
Slot phenomenon can make floatation indicators be deteriorated.Now for desliming using more equipment such as hydrocyclone, desliming bucket, inclined plate concentration
Machine etc., however these equipment are often all single use, is not achieved a preferable desliming effect, how to existing equipment or
