Embodiment Construction

[0016] Table 1 is two embodiments of the present invention, all according to figure 1 The process shown is for beneficiation, and the implementation conditions are as follows:

[0017] Scrubbing: scrubbing concentration: 50%, scrubbing time: 30min

[0018] Surface pretreatment: H 2 SO 4 : 1.75kg / t, HF: 0.25kg / t, concentration: 50%, time: 20min

[0019] Coarse flotation (selection): ammonium salt flotation collector: 3.0kg / t, PH: 2.5

[0020] Quartz fine (flotation) separation: amine salt and petroleum sulfonate mixed anion and cation collector: 3.0kg / t, PH: 2.5

[0021] Feldspar fine (flotation) separation: ammonium salt flotation collector: 2.0kg / t, PH: 2.5

[0022] Implementation Case Results Table 1

[0023]

[0024] The results show that the chemical indexes of the quartz concentrate and feldspar concentrate after the above process meet the requirements of the glass and ceramic industries, and have broad application prospects.

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 [0001] The invention relates to non-metallic ore beneficiation technology, in particular to a beneficiation and purification method for producing quartz and feldspar raw materials by using river and lake sand. Background technique [0002] With the rapid development of building materials and other industries, the glass and ceramic industries need a large amount of high-quality quartz and feldspar raw materials. If we consider the needs of industries such as casting sand, oil field fracturing sand, and water treatment filter sand, the annual demand for quartz and feldspar It is around 100-150 million tons. The mines that provide raw material guarantee for the above industries are facing the crisis of resource depletion. [0003] Under the long-term effect of hydraulic power, although the particle size distribution of river sand and lake sand is very in line with the requirements of glass raw materials, and because of its good shape (sphericity) and smooth sur...
