Metallurgical skills are listed as a scarce skill, and a career in this field is dynamic and exciting as each mineral processing plant is unique. ... Thickeners: 252282 ...
AbstractDuring production of calibrated (sized) ore, more than 50 % of the generated fines and rejects (Slimes) cannot be directly utilised in iron making due to its unfavourable granulometry, low iron content, high alumina and silica content. Approximately 10–20 % of the process plant input is discarded as slimes into slime ponds/tailing dams. Tailing …
With respect to dewatering slimes, thickening equipment is often used to concentrate the fine particles for further processing by other dewatering equipment which will then produce the final dewatered product. Over the years, nomenclature has been adopted that is specific to thickener functions in the mineral processing industries.
If the slurry contains too much slime (especially fine slime of 0.1-0.001μm), it is difficult to clear the overflow, which can also cause turbidity. ... The processing capacity of the thickener should refer to the related parameters of the cyclone, because the overflow amount of the cyclone is the ore supply capacity of the thickener. In ...

The presence of slimes in the beneficiation plants of the Iron Ore Quadrangle in Brazil have increased even more, reaching almost 40 million of tons per annum. Understanding the harmful e ect of these slimes on the iron ore flotation is a challenging and it can be useful to develop alternatives to
The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 µm up to 150 µm. The presence of the slimes (Ps < 10 µm) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to …
There is a stirring device in the machine, and the concentration effect is good.

The principle of the thickener to purify the ore washing sewage
Potash Flotation Process. Potash occurs in soft deposits generally associated with sodium chloride and varying amounts of clay slime, which because of its colloidal character, complicates the beneficiation process. Potash ores generally contain 20 to 40 percent KCL with the balance being NaCl and a small amount of clay slime, the …
