Abstract
The novel reverse flotation collecting agent for phosphorite ore is prepared from the following raw materials, wherein a mixed reagent is formed by fatty acid sodium soap and AES (ethoxylated alkyl sodium sulfate, also called fatty acid alcohol ether sodium sulfate, also called fatty alcohol polyoxyethylene sodium sulfate). The phosphorite flotation collector can obtain excellent indexes by only using sulfuric acid as an inhibitor during mineral separation, has strong collecting capability, and can still produce high-grade phosphate concentrate when the phosphorite grade is low.
Description
Technical Field
The invention relates to the technical field of beneficiation reagents, in particular to a novel reverse flotation collecting agent for phosphorite ores.
Background
The phosphate ore is a nonrenewable resource and is an important raw material in the fields of modern agriculture, industry, national defense and the like, and after the phosphate ore is crushed and ground, an ore pulp regulator, a gangue mineral inhibitor and a useful mineral collector are sequentially added into ore pulp. The phosphate of mineral is adhered to the air bubbles generated by stirring and aeration, floats to the liquid surface of the flotation machine and is scraped out, and the phosphate becomes phosphate concentrate after dehydration. Gangue minerals can also be reverse floated.
At present, the ore dressing device of national phosphate ore mountain dressing plant and phosphorus chemical industry enterprise all is basically to detach the magnesium phosphate impurity in the phosphorus ore, goes to improve the quality of phosphorus ore, obtains high-quality phosphate concentrate, the technology of adoption is reverse flotation demagging, the collecting agent is fatty acid sodium soap and active agent diethyl phthalate, the two proportions are that sodium soap accounts for 85% -90%, diethyl phthalate accounts for 10% -15%, and because the ordinary quality of water of ore pulp water is hard when the ore dressing, can influence the result of phosphorus ore flotation.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the novel reverse flotation collecting agent for the phosphorite ore, which has a good flotation effect.
In order to achieve the aim of the invention, the invention adopts the specific scheme that: the fatty acid sodium soap and AES (ethoxylated alkyl sodium sulfate, also called fatty acid alcohol ether sodium sulfate, also called fatty alcohol polyoxyethylene sodium sulfate) form a mixed medicament.
Preferably, the composition is prepared from the following components in percentage by weight: 90% of fatty acid sodium soap and 10% of AES with the content of 70% form a mixed medicament.
Preferably, the composition is prepared from the following components in percentage by weight: 80% of fatty acid sodium soap and 20% of AES with the content of 28% form a mixed medicament.
The invention has the following advantages: the phosphorite flotation collector can obtain excellent indexes only by using sulfuric acid as an inhibitor during ore dressing, has strong collecting capability, and can still produce high-grade phosphate concentrate when the phosphorite grade is low.
Detailed Description
The present invention is further described below by way of specific examples, but the present invention is not limited to only the following examples. Variations, combinations, or substitutions of the invention, which are within the scope of the invention or the spirit, scope of the invention, will be apparent to those of skill in the art and are within the scope of the invention.
The present invention will be described in further detail with reference to examples.
The formula used by the invention is a mixed medicament consisting of fatty acid sodium soap and AES (ethoxylated alkyl sodium sulfate, also called fatty acid alcohol ether sodium sulfate, also called fatty alcohol polyoxyethylene sodium sulfate).
Is prepared from the following components in percentage by weight: 90% of fatty acid sodium soap and 10% of AES with the content of 70% form a mixed medicament, the formed mixed medicament can be packaged by a woven bag, the transportation is convenient, the mixed medicament can be directly melted by water in a production field, and the using effect of the mixed medicament is not influenced.
Is prepared from the following components in percentage by weight: the mixed preparation comprises 80% fatty acid sodium soap and 20% 28% AES, and the fatty acid sodium soap and AES can be transported separately and used by mixing 80% fatty acid sodium soap and 20% 28% AES water solution.
The collecting agent of the invention is used for comparison tests on Guizhou ore, Sichuan ore and Yunnan ore by comparing the field collecting agent.
When the method is used for Guizhou ore, the raw ore P2O522.6 percent, 6.7 percent of Mgo, 68 percent of grinding fineness, 200 meshes, 400g/t of raw ore, 33.17 percent of concentrate index P2O5, 0.86 percent of Mgo, 500g/t of raw ore, 32.03 percent of concentrate index P2O5 and 1.58 percent of Mgo.
Secondly, the material is used for Sichuan ore, wherein raw ore P2O5 is 23.5%, Mgo is 5.5%, grinding fineness is 70% of 200 meshes, the consumption of the novel collecting agent is 800g/t of raw ore, the indexes of concentrate P2O5 is 32.2%, Mgo is 0.86%, the consumption of the collecting agent used in the field is 1500g/t of raw ore, the indexes of concentrate P2O5 is 30.3%, and Mgo is 1.96%.
The material is used for Sichuan ore, raw ore P2O5 is 23%, Mgo is 5.8%, grinding fineness is 74% with 200 meshes, the consumption of the novel collecting agent is 900g/t of raw ore, the indexes of concentrate P2O5 is 31.87%, Mgo is 0.76%, the consumption of the collecting agent used in situ is 1600g/t of raw ore, the indexes of concentrate P2O5 is 30.19%, and Mgo is 1.48%.
In conclusion, the results of the comparative tests show that the novel collecting agent has lower consumption than the original on-site collecting agent, the obtained phosphate concentrate has better quality and lower impurity content, and the requirements of manufacturers on the quality of the phosphate concentrate for producing high-quality phosphoric acid can be better met
Meanwhile, the novel collecting agent has cost advantage compared with the original field collecting agent, and experiments show that the consumption unit of the novel collecting agent is lower, and secondly, the AES has better hard water resistance than diethyl phthalate and is about five thousand yuan lower than the market price per ton of diethyl phthalate.
Although the invention has been described in detail hereinabove with respect to a general description and specific embodiments thereof, it will be apparent to those skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
