Embodiment 1

[0008] Take: 30% cyclohexanol, 15% cyclohexanone, 25% diethyl adipate, and 4-methyl-3-pentenone-[2] 30%.

[0009] All the percentages of the above materials are percentages by weight. The above materials are physically mixed, and the prepared medicament is a brown liquid, clear and transparent, no stratification, no precipitation, no suspended matter, chemical stability, storage in a cool and ventilated place, long-term No quality changes.

[0010] The flotation experiment of rare earth is carried out on the strong magnetic medium ore after the weak magnetic-strong magnetic separation of the medium-poor oxide ore from Baiyun Obo, Inner Mongolia by using this reagent and the rare-earth collector. The mineral contains 8.35% fluorine bastrite and lives alone. Stone 3.37%, fluorite 17.08%, hematite, feldspar, mica, sodium limestone, sodium amphibolite, etc.

[0011] The experiment was carried out under the premise of the original process flow and the slurry concentration of the grinding...

Embodiment 2

[0016] The foaming agent contains: cyclohexanol 35%, cyclohexanone 20%, diethyl adipate 17%, 4-methyl-3-pentenone-[2] 28%.

[0017] The percentages of materials are all percentages by weight. The above materials are physically mixed, and the medicament prepared by the present invention is a brown liquid, clear and transparent, without stratification, no precipitation, no suspended matter, stable chemical properties, and stored in a cool and ventilated place for a long time. Quality changes.

[0018] The experiment was conducted on the rare earth ore in Damao Banner, Inner Mongolia by using this drug in combination with a rare earth collector. The ore contained REO (REO) with a high impurity content of 8.76%, making it difficult to sort.

[0019] Experimental results:

[0020]

[0021] The experimental results show that for the original ore of Damao rare earths, the combination of this reagent and the rare earth collector for the original reagent has low cost and significantly improved...

Embodiment 3

[0023] The foaming agent contains: 25% cyclohexanol, 20% cyclohexanone, 15% diethyl adipate, and 4-methyl-3-pentenone-[2] 30%.

[0024] All percentages are percentages by weight. The above materials are physically mixed. The medicament prepared by the present invention is a brown liquid, clear and transparent, no stratification, no precipitation, no suspended matter, stable chemical properties, and stored in a cool and ventilated place for a long time. Quality changes.

[0025] Using this agent with rare earth collectors, the raw materials come from the total tailings of Baotou Steel, with complex mineral components, including fluorite, apatite, non-magnetic iron minerals, mica, pyroxene, amphibole, etc., as well as wastewater from rare earth smelting , Waste residue.

[0026] The experiment was carried out without changing the on-site process flow, grinding fineness, and slurry concentration. Using jet flotation equipment, one-time separation process, compared with the original rea...

Abstract

The invention relates to a foaming agent, in particular to a foaming agent for floating rare-earth minerals, which consists of the materials with the following weight percent: 20-40 percent of cyclohexanol, 10-20 percent of cyclohexanone, 18-25 percent of a diethy adipate, and 15-30 percent of 4-methyl-3 pentenone-[2]. The foaming agent has the advantages of strengthening foamy body, stabilizing a foam layer, facilitating the operation of the workers, having low price, small dosage, foaming performance and collection performance, avoiding peculiar smell and toxin, being beneficial to environment protection, and ensuring the health of the operating workers, which is a favorable foaming agent for selecting the rare earth matching with a collecting agent.

Description

1. Technical Field [0001] The invention relates to a foaming agent, in particular to a foaming agent for flotation of rare earth minerals. 2. Background technology [0002] At present, the foaming agent used in the flotation of rare earth minerals has a large amount of foaming agent, a high price, a strong odor and toxic, which not only causes pollution to the environment, but also damages the bodies of the operators. 3. Summary of the invention [0003] The purpose of the present invention is to provide a foaming agent with high foam strength, stable foam layer, no peculiar smell, non-toxicity, and collecting performance. [0004] Technical solution: The present invention is composed of the following materials in weight percentage: 25-40% cyclohexanol, 10-20% cyclohexanone, 18-25% diethyl adipate, 4-methyl-3-pentenone -[2] 15-30%. [0005] The above materials are physically mixed. The medicament prepared by the invention is a brown liquid, is clear and transparent, has no stratifi...
