Embodiment Construction

[0023] The invention provides an oleic acid flotation process for tourmaline ore, which will be described in detail below in conjunction with the accompanying drawings.

[0024] It mainly includes the following steps:

[0025] Step 1, taking ore body samples from shallow wells;

[0026] In the embodiment of the present invention, the whole lane method can be adopted, and the shallow well QJ 1 , QJ 2 , QJ 3 1000kg of ore body samples of No. 4, 9, and 10 were taken in the process, and combined into a beneficiation test sample.

[0027] In a preferred embodiment, the natural types of sample ores include tourmaline quartz vein type, tourmaline diorite type, tourmaline quartz cloud diorite type and tourmaline monzonite type. Almost all types of ores in the detailed investigation area are covered. Tourmaline grades range from more than 40% to more than 70%, with an average grade of 48%, which is close to the ore grade in the mining area, so the samples taken are relatively repre...

Abstract

The invention belongs to the technical field of tourmaline mineral beneficiation processes, and provides an oleic acid flotation process method for tourmaline minerals. The method comprises the following steps: collecting an ore body sample from a shallow well, crushing the ore body sample to obtain a test sample, carrying out sanding grading on the test sample, and separating tourmaline, quartz and feldspar in the test sample through oleic acid flotation. According to the method, oleic acid serves as a collecting agent to conduct flotation on tourmaline ore, rough flotation, scavenging and fine flotation are mainly included, and the method has the advantages that the recovered tourmaline content is high, the recovery rate is high, the tourmaline content in middlings and tailings is very small, and the middlings and the tailings can be directly discharged as final tailings; and the method is suitable for selecting and purifying tourmaline.

Description

technical field [0001] The invention relates to the technical field of tourmaline mineral beneficiation technology, in particular to an oleic acid flotation process method for tourmaline ore. Background technique [0002] Tourmaline is a silicate rock mineral mainly containing B (boron element) and other elements such as aluminum, sodium, iron, magnesium and lithium. It is widely used in environmental protection, cosmetics, cigarettes, air purification, coatings, textiles, water purification, electromagnetic radiation protection, health care products and other fields. With the rapid development of these fields, the demand for tourmaline and its quality of raw materials are on the rise. Therefore, how to efficiently remove impurities from tourmaline-containing ore resources is particularly important here. [0003] As a relatively common method, flotation has low investment, simple operation, and adopts a suitable chemical system, which can usually be used to separate tourma...
