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
The present invention relates to a kind of beneficiation method, belong to mining industry field.
Background technology
Present stage, mine tailing surplus was very large, also had a certain proportion of ferrous metal in mine tailing.Ferrous metal in mine tailing is mainly with Fe
2o
3form exist, because Fe2O3 does not have magnetic, and present Iron concentrator is in the majority in magnetic separation mode, to Fe
2o
3the ferrous metal that mode exists reclaims more difficult.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of beneficiation method, and the present invention recycles mine tailing, effectively reclaims with Fe
2o
3the ferrous metal that mode exists, has higher economic worth, reduces mine tailing to the destruction of environment and impact, is simplifying production procedure, is reducing production cost.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of beneficiation method, comprising:
High-iron and low-tin ore deposit is broken, add water and obtain ore pulp, send in flotation device, add floating agent, mix, obtain iron ore concentrate ore pulp, iron ore concentrate ore pulp is sent in filter, filter out ore in sand form, obtain iron ore concentrate ore pulp and be sent in drying machine dryly, obtain iron ore concentrate.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described amount of water is 2～6 times of high-iron and low-tin mineral amount.
Further, described floating agent is polyacrylamide, and the addition of described polyacrylamide accounts for 10% of ore pulp quality.
Further, described dry condition be 80～100 ℃ dry 2～10 hours.
The invention has the beneficial effects as follows:
The present invention recycles mine tailing, effectively reclaims with Fe
2o
3the ferrous metal that mode exists, has higher economic worth, reduces mine tailing to the destruction of environment and impact, is simplifying production procedure, is reducing production cost.
