Hydrocyclone   is an effective separation device that carries on two-phase fluid separation by using the centrifugal force field. It is a non-motion separation device composed of the upper cylinder and the lower cone. When the pulp is shot in the cylinder through the feeding tube in a tangent, involute or spiral way, the mixture of medium and particles produces the centrifugal field caused by rotating, the particles (or liquid phase) with different density produce the different trajectories. Under the action of centrifugal force, medium resistance and force field, the coarse particles and heavy particles moving towards the periphery, and are discharged from the spigot through the cone-shaped body; the fine particles and low-density particles (or liquid phase) move toward the center and are discharged by the overflow pipe, finally the classification of solid particles and the separation of fluids with different densities are realized. In the ore dressing, hydrocyclone is mainly u

Cyanidation has a history of more than 200 years since it was applied to gold and silver ore extraction in 1887. At present, cyanidation is still one of the main   gold extraction process   due to its high recovery rate, high adaptability to ore and local production. Generally, cyanidation methods can be divided into two categories: agitation cyanidation and percolation cyanidation. Among them, agitation cyanidation is mainly used to treat flotation gold concentrate or all-slime cyanidation. Percolation cyanidation is mainly applied in dealing with low-graded gold ores. One. Agitation cyanidation gold extraction process Agitation cyanidation gold extraction process mainly includes two kinds of gold extraction processes. One is the cyanidation-zinc replacement process (CCD method and CCF method) which uses the zinc powder (silk) to replace and recover the gold after the continuous countercurrent washing. Another is the unfiltered cyanidation carbon slurry process (CIP method an

There are many factors affecting the   flotation process , including non-adjustable factors and adjustable factors. Among them, non-adjustable factors refer to the ore property, adjustable factors mainly include grinding fineness, pulp concentration, pulp pH value, reagent system, pulp temperature, water quality, flotation time and so on. But, do you know the influence of these factors on the flotation process? One. Ore property Ore property mainly includes chemical composition of ore, mineral composition, ore structure, occurrence state of useful and harmful elements, physical and chemical properties of ore, etc. The fluctuation of ore grade will increase the controlling difficulty of the flotation process. Among them, the oxidation rate of ore has a great impact on the flotation: 1. The oxidation of metal minerals and gangue minerals will change the original mineral and ore structure, and then form a series of earthen or clay minerals, which greatly increases the amo
