Abstract
The invention discloses a beneficiation method for producing quartz and feldspar by using river and lake sands. The method is characterized by comprising the following steps of: (1) performing beneficiation to river (lake) sands by 'ore washing, desliming, grading, reselecting, magnetic selecting' and other conventional physical methods to control the product granularity and reduce the content of Fe2O3; (2) coarse separation, wherein primary separation of quartz and feldspar minerals can be realized by utilizing a flotation process; and (3) selected iron removal, wherein the content of Fe2O3 of quartz and feldspar minerals can be reduced by utilizing selection (flotation) process. After treatment by the process, quartz and feldspar for glass, ceramic and other industries can be widely obtained from river (lake) sands. The beneficiation method has the advantages that high-quality quartz and feldspar can be effectively separated from river and lake sands, so that a substitution resource is provided to the quartz and feldspar raw materials for the glass and ceramic industries, the environment is protected, the cost is reduced, and the risk that resources are increasingly exhausted can be reduced.
Description
Technical field
The present invention relates to the nonmetallic ore technique of preparing, particularly utilize the river lake sand to produce the ore dressing method of purification of quartz and feldspar raw material.
Background technology
Follow the fast development of industries such as building materials; Glass, china and pottery industry needs the quartz and the feldspar raw material of a large amount of high-qualitys; Cross industry requirements such as filter sand if consider moulding sand for casting, oil field compression fracture sand, water treatment again, quartzy and feldspar year expense about 1.0 ~ 1.5 hundred million t.Be the mine that above-mentioned industry is supplied raw materials and ensured, be faced with the exhausted day by day crisis of resource.
River sand lake sand is under the long term of waterpower, and is though grain size distribution extremely meets the requirement of glass raw materials, good because of shape (sphericity) in addition; Smooth surface; Be expected to be applied in industries such as casting, oil field, water treatments, but complicated because of the impure mineral source, composition is different; Except that the building industry that is widely used, also can't be applied in the above-mentioned industry at present.
The river lake sand is generally by quartzy (SiO
2), potassium (sodium) feldspar (K (Na) AlSi
3O
8), tens kinds of impure minerals of calcareous silicate and other form.Ensaying shows that river (lake) sand is under natural long term, and physical propertys such as the size distribution of quartz, feldspar and impure mineral, proportion are very approaching, and conventional physical upgrading method (classification, gravity treatment, magnetic separation) can't make its effective separation.Further research shows, above-mentioned mineral are under the long term and dip-dye of waterpower, and surface nature has " convergence ", causes the poor selectivity of FLOTATION SEPARATION.
Summary of the invention
The object of the invention is exactly can't make quartzy defective of effectively separating with feldspar in the lake sand of river, a kind of beneficiation method of producing quartz and feldspar with the river lake sand that provides in order to solve conventional beneficiation method.
The technical scheme that the present invention adopts is following:
A kind of beneficiation method of producing quartz and feldspar with the river lake sand is characterized in that may further comprise the steps:
(1) earlier the river lake sand being carried out conventional physics method ore dressing handles: comprise screening-scouring-desliming-classification-gravity treatment-magnetic separation, the granularity of control product reduces Fe
2O
3Content; Purpose is to sieve the impurity elimination thing, cleans graded desliming matter, and the granularmetric composition of control product meets the demands, and isolates heavily (magnetic) property mineral in advance through gravity treatment, magnetic dressing process, reduces Fe as far as possible
2O
3Content;
(2), surface preparation: pre-treatment job is carried out in swaging machine, cleans concentration and is controlled at 40 ~ 70%, and the scouring time is 5 ~ 60min, and scouring media adopts hydrochloric acid, sulfuric acid or hydrofluoric acid, and the medium consumption is sloughed liquid medicine at 1.5 ~ 4 kg/t after the preliminary treatment; Its purpose is to enlarge the surface differences of mineral, improves the selectivity of thick (floating) choosing;
(3) feldspar rough floatation: on the basis of surface preparation; Add sulfuric acid or hydrofluoric acid, adjustment rough floatation pulp PH value is 1.5 ~ 3, and adding ammonium salt class flotation collector 1.5 ~ 5kg/t sizes mixing; Collecting agent is the ammonium salt class; Like lauryl amine ~ octadecylamine salt or its mixture, utilize reverse floatation process that feldspathoid is flotated, realize that quartz separated with the thick step of feldspathoid;
(4) feldspar cleaner flotation step: the feldspathoid flotation thing with rough floatation goes out, under above-mentioned pH value 1.5 ~ 3 environment, add ammonium salt class flotation collector 0.5 ~ 3.5 kg/t and size mixing, carry out direct flotation, floating upward thing is final feldspar washed ore;
(5) quartzy cleaner flotation: in step (3), remove in the flotation fluid of feldspathoid flotation thing; Adjustment PH1.5 ~ 3; Add 1.5 ~ 3.5 kg/t amine salt classes and mahogany acid salt zwitterion hybrid collector and carry out reverse flotation; Sand setting is final quartzy washed ore, and the supernatant in the reverse flotation process is quartzy chats, returns feldspar rough floatation step (3).
The invention has the advantages that:
The present invention effectively from the river lake sand isolate high-quality quartz and feldspar, quartz and the feldspar raw material required for glass, china and pottery industry provide an alternate resources, protected environment, have reduced cost, and have alleviated to be faced with the exhausted day by day crisis of resource.
Description of drawings:
Fig. 1 is a process chart of the present invention.
The specific embodiment:
Table 1 is two embodiment of the present invention, all carries out ore dressing by flow process shown in Figure 1 and handles, and implementation condition is following:
Clean: clean concentration: 50%, the scouring time: 30min
Surface preparation: H
2SO
4: 1.75kg/t, HF:0.25kg/t, concentration: 50%, the time: 20min
Thick floating (choosing): ammonium salt class flotation collector: 3.0kg/t, PH:2.5
Quartzy smart (floating) choosing: amine salt class and mahogany acid salt zwitterion hybrid collector: 3.0kg/t, PH:2.5
Feldspar smart (floating) choosing: ammonium salt class flotation collector: 2.0kg/t, PH:2.5
Case study on implementation is table 1 as a result
The result shows: the quartzy washed ore after above-mentioned PROCESS FOR TREATMENT and feldspar washed ore each item chemical index satisfy the requirement of glass, ceramic industry, have a extensive future.
