Embodiment 1

[0041] Embodiment one is basically as attached figure 1 Shown:

[0042] A beneficiation process for resource utilization of low-grade celestite, comprising the following steps:

[0043] Step 1, raw ore crushing: take the raw ore, which mainly contains about 30% strontium sulfate, and other impurities such as calcite, dolomite, gypsum, silt and a small amount of iron, aluminum, etc., and use the jaw crusher to crush the raw ore Coarse particles with a diameter of 3-7 cm are obtained, and then a pulverizer is used to crush the coarse particles until fine particles with a diameter of less than 4 mm are obtained.

[0044] Step 2, pickling: add the fine particles obtained in step 1 into the acid tank, add hydrochloric acid with a mass concentration of 30% into the acid tank, and use stirring to make the hydrochloric acid fully contact and react with the fine particles, so as to realize the removal of fine particles The pickling process keeps the pH of the solution at 1; the gas a...

Embodiment 2

[0067] The difference between the second embodiment and the first embodiment is that in the second embodiment, the solution used for tail gas absorption is sodium carbonate solution, which can achieve the same effect as sodium hydroxide.

Abstract

The invention relates to the technical field of beneficiation processes, and particularly discloses a beneficiation process for resource utilization of low-grade celestite, which comprises the following steps: step 1, crushing raw ore: crushing the raw ore to obtain fine particles with the diameter of less than 4mm; step 2, acid pickling: carrying out acid pickling on the fine particles obtained in the step 1 by adopting hydrochloric acid; step 3, tail gas absorption: introducing gas generated in the pickling process into an alkaline solution for absorption; step 4, primary separation: separating solid and liquid generated after acid pickling; step 5, neutralizing; step 6, heating and removing impurities: heating the solution obtained in the step 5, and adding quick lime; step 7, secondaryseparation: separating the solid and the liquid obtained in the step 6; step 8, cleaning celestite; and 9, cleaning silt. According to the scheme, the problem that in the prior art, wastewater, wastegas and waste residues pollute the environment in the beneficiation process of low-grade celestite is solved.

Description

technical field [0001] The invention relates to the technical field of mineral processing technology, in particular to a mineral processing technology for resource utilization of low-grade celestite. Background technique [0002] Strontium carbonate is an important strontium compound. Due to its strong X-ray shielding function and unique physical and chemical properties, it is widely used in the fields of electronics, military industry, metallurgy, medicine and optics. Inorganic chemical materials, celestite is mainly used for the production of strontium carbonate at present. [0003] my country's celestite resources are relatively rich, but the ore grade is low and the impurity content is high, so it can be used as a raw material for the production of strontium carbonate after beneficiation and removal of impurities; the existing celestite after beneficiation is very fine, and the ore powder usually obtained is 200 It is not applicable to the existing process of producing i...
