Abstract
The method that flotation collector produces product quality is effectively improved the present invention relates to a kind of, is carried out according to the following steps:Raw material needed for producing collecting agent is placed in steam reaction kettle, being stirred and heated to 80 90 DEG C is completely dissolved it, then appropriate caustic soda saponification 1 1.5 hours under the conditions of 80 90 DEG C are added, add 2% 10% citric acid, continue to stir 12 hours under the conditions of 70 90 DEG C, obtain the higher collecting agent of saponification degree.The present invention can effectively solve in flotation agent production saponification process because system viscosity it is too big caused by the incomplete product quality of collecting agent saponification it is not up to standard the problem of.
Description
Technical field
The present invention relates to a kind of method of flotation collector production, especially one effectively improves flotation collector production product
The method of quality.
Background technology
Flotation collector is as the important medium of mineral processing production, and product quality and its stability are to the steady of ore dressing plant production run
Surely have very important significance.Compression due to flotation agent manufacturer to production cost, current country's flotation collector
Production belongs to very easy soap production technique, many key flows that can strengthen saponification, promote product quality stabilization
All it is omitted, causes the collecting agent quality fluctuation of in the market larger.Therefore, a kind of equipment investment is few, need to only be caught in traditional flotation
Receiving the method for carrying out simply transforming the stable lifting that can be achieved with product quality on agent producing process becomes particularly urgent.
The content of the invention
The purpose of the present invention is in order to solve drawbacks described above and problem, and the one kind provided effectively improves flotation collector production
The method of product quality.The method equipment investment that the present invention is provided is few, simple to operate, can increase substantially flotation collector product
Quality and ensure production product quality stability.The citric acid being related in the present invention has faintly acid, in process of production
The soap base knurl formed in saponification process can be effectively neutralized, enables the raw materials such as aliphatic acid fully to contact with caustic soda to reach that saponification adds
Strong effect.The depth saponification of fatty acid soaps contributes to product to reach that the mixture of a variety of crystalline phases assigns collecting agent more multi-effect.
The present invention is realized by following technology：
It is a kind of to effectively improve the method that flotation collector produces product quality, carry out according to the following steps:Collecting agent will be produced
Required raw material is placed in steam reaction kettle, and being stirred and heated to 80-90 DEG C is completely dissolved it, is then added appropriate caustic soda and is existed
Saponification 1-1.5 hours under the conditions of 80-90 DEG C, it is characterised in that：2%-10% citric acid is added, under the conditions of 70-90 DEG C
Continue to stir 1-2 hours, obtain the collecting agent of good quality of product.
The citric acid is the citric acid of content more than 99%.
The method that the present invention is provided can be prevented effectively from flotation collector production saponification process because generation soap base knurl is wrapped
The raw materials such as aliphatic acid prevent the problem of raw material is from abundant saponification.This method can reduce saponification system viscosity, in identical stirring intensity
Under the conditions of enable aliphatic acid fully to contact with caustic soda to reach the complete purpose of saponification.This method is given birth to suitable for all flotation collectors
Production. art.It is simple to operate and product quality can be increased substantially due to reforming equipment less investment, the life to improving flotation collector
Produce efficiency significant.
