Problems solved by technology

The iron metal in the tailings is mainly Fe 2 o 3 Exist in the form of Fe2O3, because Fe2O3 has no magnetism, and most of the current iron concentrators use magnetic separation, for Fe2O3 2 o 3 Ferrous metals that exist in ways that are more difficult to recover

Embodiment 1

[0014] A mineral processing method, comprising:

[0015] Crush the high-iron and low-tin ore, add water to obtain ore pulp, the amount of water added is 6 times the quality of the high-iron and low-tin ore, send it into the flotation machine, and add the flotation agent polyacrylamide, the addition of the polyacrylamide accounts for 10% of the pulp. Mix 10% of the mass evenly to obtain iron concentrate slurry, send the iron concentrate slurry into a filter, filter out the ore sand, and send the iron concentrate slurry to a dryer for drying. The drying condition is 80°C. After 8 hours, the iron ore concentrate was obtained, and the recovery rate of the iron ore concentrate reached 85%.

Embodiment 2

[0017] A mineral processing method, comprising:

[0018] The high-iron and low-tin ore is crushed, and water is added to obtain ore pulp. The amount of water added is 5 times the quality of the high-iron and low-tin ore, and it is sent to a flotation machine, and the flotation agent polyacrylamide is added. Mix 10% of the mass evenly to obtain the iron concentrate slurry, send the iron concentrate slurry into a filter, filter out the ore sand, and send the iron concentrate slurry to a dryer for drying. The drying condition is 100°C. After 10 hours, the iron ore concentrate was obtained, and the recovery rate of the iron ore concentrate reached 81%.

Abstract

The invention relates to a beneficiation method which includes breaking high-iron low-tin ore, adding water into the ore to obtain ore pulp, delivering the ore pulp into a flotation machine, adding a flotation reagent, evenly mixing the pulp and the reagent to obtain iron ore concentrate pulp, filling the iron ore concentrate pulp into a filtering machine, removing ore sand through filtering, delivering the obtained iron ore concentrate pulp into a dryer, and drying the iron ore concentrate pulp to obtain iron ore concentrate. By means of the beneficiation method, tailings are recycled, iron existing as Fe2O3 is effectively recycled and has high economical value, damage and effects of the tailings to the environment are reduced, a production process is simplified, and production cost is reduced.

Description

technical field [0001] The invention relates to a beneficiation method, which belongs to the field of mining. Background technique [0002] At this stage, there is a large amount of tailings remaining, and there is still a certain proportion of iron metal in the tailings. The iron metal in the tailings is mainly Fe 2 o 3 Exist in the form of Fe2O3, because Fe2O3 has no magnetism, and most of the current iron concentrators use magnetic separation, for Fe2O3 2 o 3 It is difficult to recover the iron metal that exists in this way. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of ore dressing method, the present invention recycles tailings, effectively reclaims Fe 2 o 3 The iron metal that exists in the form of iron has relatively high economic value, reduces the damage and impact of tailings on the environment, simplifies the production process, and reduces the production cost. [0004] The technical...
