jjf type flotation machine
Improvement: Shallow groove, the stator lower than the impeller, large slurry circulation volume, low energy consumption; the stator is a cylinder with an elliptical hole which is conducive to the dispersion and mixing of pulp and air. Umbrella shaped dispersion cover with hole keeps the pulp surface stable.
JJF flotation machine(floatation cell) is a new type of flotation equipment advanced in China. It can be widely used in the selection of non-ferrous metals, ferrous metals and non-metallic minerals. It is suitable for rough selection and sweeping of large and medium-sized flotation plants.
Large clearance between impeller and stator, the stator is a cylinder with elliptic hole, and it is good for mixing and dispersing the gas and pulp. The height of stator is lower than the impeller, pulp circulation volume is large, and it can be reached at 2.5 times of others.
When the impeller rotates, eddy current is generated in the vertical cylinder and the draft tube. The eddy current forms a negative pressure, and the air is sucked from the intake pipe and sucked in the impeller and stator regions and through the draft tube. Mix the pulp. The slurry gas mixing flow is moved by the impeller in a tangential direction, and then converted into a radial motion by the action of the stator, and uniformly distributed in the flotation tank. The mineralized bubbles rise to the foam layer, and the unilateral or bilateral scraping is the foam product.
effect of protonation and deprotonation reactions of clay on regulating pyrite flotation in the presence of clay - sciencedirect
The slurry pH shows significant effects on flotation, but the root cause of pH affecting flotation in the presence of clay is still not fully understood. In this work, the mechanisms of protonation and deprotonation reactions of clays at weakly acidic (pH = 4.5) and alkalescent (pH = 9.0) environment affecting pyrite flotation were investigated. The pyrite flotation in the presence of clays (montmorillonite (Mt), kaolinite (Kaol) and illite (I)) was improved with the deprotonation reactions at pH 9.0 compared with the protonation at pH 4.5. The protonation reactions made the edge surfaces of all the clays and the O basal surface of Kaol positively charged. Hence, the house-of-cards structure of Mt and the slime coating of Mt and Kaol occurred, which depressed the pyrite flotation. However, the deprotonation of clay took place at pH 9.0, and thus the face-to-face associations of clay were clearly observed by scanning electron microscopy (SEM). In addition, the negative potential of clay also increased with the deprotonation of clay, which affected the DLVO total interaction energy, making the attraction turning into the repulsive tendency between pyrite and clay. However, pyrite grade showed a little or no increase in the presence of I, which was ascribed to the 2:1 structure and non-swelling nature of I. Such findings can not only help understand the protonation and deprotonation of clay on regulating flotation in the presence of clay, but are expected to provide guidance for mitigating the negative effects of clay during the flotation in the future work.
