how to prevent and reduce excessive mud in grinding pulp

how to prevent and reduce excessive mud in grinding pulp? In flotation processing , Common measures to prevent and reduce slime include: (1) reduce and prevent the formation of slime: multi-stage grinding process and stage dressing process can be adopted.To choose grinding and grading equipment correctly, improve the efficiency of the spiral classifier; (2) add to eliminate the harmful effects of mineral mud agents: commonly used water glass, soda, caustic soda, etc.;It can reduce the flocculation of slime.In order to reduce the harmful effect of a large number of adsorption agents, the method of subsection dosing can be considered. (3) desliming of the grinding raw ore before flotation is carried out to discard it as tailings.If the content of useful ingredients in the slime is high, the removed slime can be treated by flotation alone or sent to hydrometallurgy. Commonly used desliming method: (1) grading machine desliming;(2) hydrocyclone desliming;(3) in special circumstances, i

Effect of grinding particle size on flotation

图片
Effect of grinding particle size on flotation In the flotation machine flotation process, both excessively coarse ore particles (greater than 0.1mm) and extremely fine ore particles (less than 0.006mm) do not float well and the recovery rate is low. In the flotation of coarse particles, due to the large weight, the ore particle shedding force increased.It requires :(1) the use of sufficient quantities of the most effective collecting agent;(2) increase the air inflation of pulp to cause large bubbles and increase the amount of microbubbles precipitated out of water;(3) the stirring strength of pulp shall be appropriate;(4) pulp concentration should be appropriately increased;(5) the scraper should be rapid and stable when blowing bubbles. In the flotation of very fine particles (usually less than 5 ~ 10 m of slime), (1) because the slurry quality is very small, it is easy to adhere to the coarse surface, making the coarse floatability reduced, making the selectivity bad;(2) because

working principle of single hydraulic cone crusher

working principle of single hydraulic cone crusher At present, hydraulic cone crusher is widely used abroad.Using hydraulic technology, using hydraulic positioning mechanism, reliable work, and automatically remove iron pieces such as non-breakable material.The hydraulic system plays three roles: supporting the cone of the crusher, adjusting the discharge port and realizing overload protection.The hydraulic cone crusher can adjust the ore outlet and remove the non-broken material in about 1 minute, which shows that it is more advanced than the spring cone crusher. Hydraulic cone crusher is divided into single cylinder and multi-cylinder type. The lower end of the main shaft of the movable cone 3 is inserted into the eccentric shaft sleeve 4 and supported on the spherical disc above the piston of the oil cylinder;The piston is supported by high pressure oil below it.Because of the rotation of eccentric shaft sleeve, the moving cone makes conical movement. The vertical shaft 1 and m

The affect of cone crusher product shape

The affect of cone crusher product shape Cone crusher is a common crushing equipment, the main object of its work for ore materials, its particle shape (material particle geometry) is the main index of crushing product quality evaluation, usually can be divided into cubic and needle flake particle. The mass fraction of needle flake particles in the crushed products is needle flake rate.In the construction field, the increase of the needle flake particles in the concrete aggregate will lead to the decrease of the overall compressive strength of the building and increase the cement consumption in the construction process.Similarly, in asphalt mixtures, the increase of needle flake particles will also lead to the decrease of the overall density and compressive and tensile strength of the mixture.Thus it can be seen that reducing the rate of needles is crucial to the quality of broken products. Related research found that the material before entering the crusher, after screening or parti

Global iron ore production set for modest growth

图片
Global iron ore production set for modest growth 【Global iron ore production will grow due to mine expansions in Brazil and increasing output from India, according to the latest analysis from Fitch Solutions. Meanwhile, output growth in China will decline on the back of falling ore grades and high production costs. The report found global iron ore production will grow modestly from 3,322mnt in 2019 to 3,430mnt by 2028. This represents average annual growth of 0.2% during 2019- 2028, which is a significant slowdown from an average growth of 4.5% during 2009-2018. On the one hand, supply growth will be primarily driven by India and Brazil where major miner Vale is set to expand output with its new mine. On the other hand, miners in China, which operate at the higher end of the iron ore cost curve, will be forced to cut output due to falling ore grades.By DANIEL BRIGHTMORE 】 Shanghai Shuosen Mining Machine Co.,Ltd, it is one of the high-tech group company with the technology
