Embodiment 1

[0026] Such as figure 1 Shown, the embodiment of the present invention provides a kind of application of metallurgical surfactant, will have figure 1 Structured metallurgical surfactant 2-butene-1,4-bis(dodecylpyrrolidinyl ammonium bromide) is used as collector in lapis lazuli ore flotation, water glass is inhibitor, terpineol oil As a foaming agent, when the lapis lazuli ore contains 35% strontium sulfate, and the particle size is -200 mesh accounting for 90%, add water to adjust the slurry to a mass concentration of 40%, and adopt a flotation process of one roughing, one sweeping, and three selections The process, the flotation temperature is 20-30°C, and the reagent system is: adding 500g / t 2-butene-1,4-bis(dodecylpyrrolidinyl ammonium bromide) and 150g / t terpineol oil for roughing , add 200g / t 2-butene-1,4-bis(dodecylpyrrolidinyl ammonium bromide) to the sweeping, add 1200g / t water glass to the first selection, add 800g / t to the second selection t water glass, select and...

Embodiment 2

[0030] The difference between this example and Example 1 is that when the day’s lapis lazuli ore contains 50% strontium sulfate, and the particle size is -200 mesh accounting for 95%, add water to adjust the slurry to a mass concentration of 35%, and use one roughing and one sweeping , Twice selected flotation process, flotation temperature is 5-15 ℃, reagent system is: add 800g / t2-butene-1,4-bis(dodecylpyrrolidinyl ammonium bromide ), 150g / t pine alcohol oil, adding 300g / t2-butene-1,4-bis(dodecylpyrrolidinyl ammonium bromide) for sweeping, adding 1000g / t water glass for the first selection, and adding 1000g / t water glass for the first selection Secondary selection adds 500g / t water glass; A kind of metallurgical surfactant 2-butene-1,4-bis(dodecylpyrrolidinyl ammonium bromide) in the present invention and collector agent commonly used The results of the flotation comparison experiment are shown in the table below:

Abstract

The invention provides application of a metallurgical surfactant, belonging to the field of metallurgical surfactants. The application based on the metallurgical surfactant comprises the metallurgical surfactant, water glass, terpenic oil and an application method. The application method comprises the following steps: after celestite ore is smashed, adding water for size mixing to form flotation pulp; adding the metallurgical surfactant and the terpenic oil into the flotation pulp for foaming, and performing primary roughing through a flotation process; after primary roughing is carried out, adding the metallurgical surfactant into the flotation pulp again, and conducting primary scavenging through a flotation process; and after primary scavenging, subjecting beneficiation pulp to concentration twice to three times through a flotation process, wherein during each time of concentration, different amounts of water glass are sequentially added into the flotation pulp to serve as inhibitors. When the metallurgical surfactant is used as a celestite ore flotation collecting agent, the celestite ore collecting capacity of the metallurgical surfactant at a low temperature is high, selectivity is good, the grade and the recovery rate of the celestite ore are improved, and good application and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to the application of a metallurgical surfactant. Background technique [0002] Metal strontium and its compounds are known as "metal monosodium glutamate" as raw materials in the new material industry, and are widely used in many fields such as electronic information, chemical industry, light industry, medicine, ceramics, glass, pyrotechnics, metallurgy, and military affairs. And with the advancement of science and technology and the development of industrialization, the uses of various strontium salt products are gradually expanding, and strontium salt products will surely have good application prospects and market demand. Celestite is the main form of strontium ore and an important raw material for refining strontium chemicals. my country's proven celestite reserves are at the forefront of the world, mainly distributed in Qinghai, Shaanxi, Yunnan, Hubei, Chongqing, Ji...
