Embodiment Construction

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] The process flow of desliming-flotation celestite concentrate in the invention includes a crushing process, a rod grinding process, a flotation process, a concentration process, a first-stage desliming process and a second-stage desliming process; the flotation process includes: a roughing process, a sweeping process Process, sweep selection process, first-level selection process, second-level selection process, third-level selection process, fourth-level selection process, fifth-level selection process;

[0026] Wherein: a) the described rod grinding process is that the particle size is -5mm, SrSO 4 The raw ore with a grade of 44.34% is ground into a desliming particle size of -0.015~-0.020mm;

[0027] b) the described classification overflow process is to use sand pump to send the sand ore to the desliming bucket (8) to carry out the first stage...

Abstract

The invention relates to a process for separating mineral of Celestine, especially relating to a finished ore process of desliming-multiple selection. The inventive method comprises: the ore is processed with rod milling, secondary desmliming, spiral classifying, floatation-roughing separation, secondary scavenger, and fifth classifying. The invention comprises following advantages: the inventive process has better mineral separation index when it is used to classify the Celestine with large content of low-grade mud, while the finished ore productivity is 37.82-42.09%, the content of SrSO4 is 75.75-80.10% and the recovery ratio is 75.17-79.59%; the fifth floatation device has large handling capacity, lower water consumption, lower cost of finishing ore, and lower medicament consumption with simple device. The invention has stable process, simple operation and wide application in the finishing-separation production of Celestine, while it can supply high grade Celestine finished ore for producing strontium carbonate.

Description

technical field [0001] The invention relates to a celestite beneficiation process, in particular to a desliming-flotation celestite concentrate process. Background technique [0002] Strontium carbonate is a basic inorganic chemical raw material. Because of its strong X-ray shielding function and unique physical and chemical properties, it is widely used in various fields such as electronics, military industry, metallurgy, medicine, food and optics. Strontium is the element with the smallest abundance among the alkaline earth metal elements. Among the more than 40 kinds of strontium minerals found in nature, the industrial minerals that can be used are mainly celestite and strontium ore, and the raw materials used to produce strontium carbonate are mainly strontium. Bluestone and strontium ore, and celestite is the main raw material for strontium recovery. [0003] The Dafengshan celestite mine in Qinghai Province is a super-large sedimentary deposit. The mine is located in...
