Embodiment 1

[0030] Embodiment 1: Garnet flotation test:

[0031] A. The raw material, garnet ore, is crushed to -3mm by jaw crusher and roller crusher, and the ore is ground to -0.074mm by conical ball mill, accounting for 30%.

[0032] B. Desliming, using spiral chute gravity separation and desliming, the deslimed material is the flotation raw material.

[0033] C. Slurry adjustment, use a mixing tank to adjust the slurry, and adjust the slurry concentration of the flotation selected raw materials to 50%, the dosage of the agent is as follows: adjuster sulfuric acid, the dosage is 1000g / t, the pH value of the pulp is 4~5, and the collector sodium petroleum sulfonate Combination agent with salicylic hydroxamic acid (the ratio of agent is 3:1), the dosage of agent is 1500g / t. The stirring time was 5 minutes.

[0034] D. Flotation test, start the equipment, open the aeration device, add water to the top of the middle cylinder, adjust the ore discharge valve to keep the water volume in the...

Embodiment 2

[0038] Embodiment 2: kyanite flotation test:

[0039]A. Test sample treatment, kyanite is crushed to -3mm by jaw crusher and roller crusher, and dry-type magnetic separation is carried out by dry-type permanent magnet strong magnetic separator, discarding biotite, Weak magnetic mineral, the magnetic field strength is 850KA / m. Grind the non-magnetic material until the content of -0.074mm accounts for 50%, carry out gravity separation and throw tailings in the spiral chute, discard light minerals such as muscovite and fine mud, and prepare the raw materials for flotation.

[0040] B. Slurry adjustment, use a mixing tank to adjust the slurry, and adjust the slurry concentration of the flotation selected raw materials to 50%, and the dosage of the agent is as follows: 300g / t of citric acid as an adjustment agent, 20g / t of polyacrylamide, and self-developed collector Z-401 The dosage of medicine is 1000g / t. The stirring time was 5 minutes.

[0041] C. Flotation test, start the e...

Abstract

The invention discloses a coarse grain flotation machine which comprises a rack. A sorting barrel, a bearing pedestal support and a motor seat are arranged on the rack. A large belt wheel is arranged at the top end of a stirring shaft. The bottom end of the stirring shaft stretches into the sorting barrel and is provided with a stirrer. The sorting barrel is composed of an inner barrel, a middle barrel and an outer barrel. The middle barrel is fixed to the outer wall of the inner barrel. The outer barrel is fixed to the outer wall of the middle barrel. The upper edge of the outer barrel is higher than the upper edge of the middle barrel. The upper edge of the middle barrel is higher than the upper edge of the inner barrel. An ore feed opening is formed in the bottom of the inner barrel. A filling medium is arranged on the upper middle portion of the inner barrel. A tailing outlet is formed in the bottom of the middle barrel. A concentrate outlet is formed in the bottom of the outer barrel. The coarse grain flotation machine is suitable for separation and purification of minerals which are coarse in flotation target mineral grain size and meanwhile are influenced by fine silt in the flotation process; and the coarse grain flotation machine is mainly applied to aluminosilicate non-metal ore sorting and flotation and separation of oxidized ore and other minerals, such as flotation of multiple minerals of andalusite, kyanite, phosphorite, rare earth ore, oxidized ore, other aluminosilicate and the like.

Description

technical field [0001] The invention belongs to the technical field of mineral processing flotation, and in particular relates to a coarse-grain flotation machine, which is suitable for flotation separation of non-metallic minerals, oxidized ores and other minerals whose particle size is relatively coarse and affected by fine mud. Background technique [0002] Flotation is a method of sorting according to the difference in the physical and chemical properties of the surface of mineral particles and the difference in mineral floatability. Flotation machine is an important equipment to realize this process. Flotation is widely used. It is mainly used for sorting copper, lead, zinc, gold, molybdenum, nickel and other non-ferrous metals. It can also be used for sorting ferrous metals and non-metallic ores. [0003] Conventional flotation machines are mainly designed for metal ores, and metal ores, especially sulfide ores, have good collection performance and chemical adhesion, b...
