Abstract
The invention relates to a method for using a collector prepared from illegal cooking oil in fluorite flotation. The collector is prepared by the following steps: (a) purifying and extracting illegal cooking oil; and (b) subjecting the purified and extracted illegal cooking oil obtained by the step (a) to a hydrolysis reaction and thus obtaining the collector for use in ore floatation. When the collector prepared from the illegal cooking oil, which is used in the invention, is used in fluorite flotation, the selectivity of the collector is improved, and the technical index and economic index of the flotation can be improved. As the illegal cooking oil is used as the raw material for preparing the collector, the technical scheme adopted by the invention has a great significance for avoiding environment pollution, simplifying production process, reducing food safety threats and the like.
Description
Technical field
The invention belongs to the collecting agent field of flotation of ores, particularly relate to a kind of collecting agent with the waste oil preparation and be used for the method for fluorite.
Background technology
Fatty acid compound has important application in the flotation of mineral as collecting agent, fatty-acid collector commonly used comprises higher fatty acids and sodium salt thereof, for example: oleic acid, enuatrol, and the product that contains multiple fatty acid composition that extract from animals and plants and PETROLEUM PROCESSING byproduct, papermaking wastewater, as animal, plant fatty acid (soap), aphthenic acids (soap), oxidized paraffin wax (soap), tall oil (soap) and purified product thereof.
Because aliphatic acid has very active carboxyl functional group, so can carry out flotation to a lot of mineral.Fatty acid compound, as the anion collecting agent, is widely used in the flotation of mineral for a long time.But the mineral of its flotation mainly contain: 1. alkaline-earth metal salt mineral, as scheelite, fluorite, fluorite, barite etc.; 2. metal oxide-type mineral, as bloodstone, pyrolusite, cassiterite, wolframite, ilmenite etc.; 3. transition metal oxyacid salt mineral, as malachite, chessy copper, smithsonite etc.; 4. silicate mineral, as beryl, spodumene, zircon, andradite, tourmaline etc.
Fatty acid collecting agent mainly synthesizes by chemical method, China just is used for oxide ore flotation with soybean oil, camphor seed oil, achene of Siberian cocklebur wet goods vegetable oil raw materials through processing the synthetic fatty acid collecting agent in research as far back as five sixties of twentieth century, there is lack of raw materials due to it, then the research collecting agent of tal fibre wet goods as oxide ore flotation.Tall oil is the byproduct that obtains in the alkali paper-making process take timber as raw material, only has pine alkali paper-making factory that production is just arranged.Owing to being subject to the national impact that limits disafforestation and close little paper mill policy, the raw material sources of tall oil are more nervous.And paper mill is for number one, turns to gradually to produce refining tall oil and wait the industrial chemicals sale as making paint, and this has all limited the tal fibre oil supplying.The seventies and eighties, many to microorganism petro-jelly fermentation synthetic fatty acid research and comparison.After the nineties, about the research and development of fatty-acid collector, advance by leaps and bounds, various aliphatic acid arise at the historic moment under the condition of different compound, modifications.Some scholar has carried out the research with raw material synthetic fatty acid collecting agents such as oil foot or petroleum by-products.
But present fatty acid collecting agent shortcoming also clearly, is mainly the poor selectivity to mineral, and reagent consumption is large; The solubility of medicament is low, disperse in water bad, the collecting poor performance, the actual use needs emulsification often; Not anti-hard water; When temperature is low, flotation effect is bad, so that the flotation of need to heating; Need simultaneously to select gangue mineral inhibitor etc. during application.
The normal fat acids collecting agent that uses due at present ore dressing is poor selectivity at normal temperatures, wanting to obtain effect preferably has to ore pulp is heated to more than 30 ℃ and carries out flotation, need to set up the device to warming up pulp, so just produce the very high expense of heating, increase the flotation cost.
Patent CN1031490A discloses a kind of collecting agent that utilizes the flotation oxide ore that waste material that refined plant when oil abandon makes for raw material, the raw material that the preparation of this collecting agent is used is the waste material of refined plant oil, in raw material, the composition structure of aliphatic acid is not ideal enough, and the flotation temperature of flotation mineral is higher.
Patent CN1097152A discloses a kind of synergist of applying and has promoted the flotation effect of fatty-acid collector, but applying synergist can increase the cost of collecting agent.
Patent CN1343531A discloses a kind of preparation method of floatation catcher of iron ore, this patent is disclosed is that croude fatty acids or fatty acid mixed are the collecting agent of base stock preparation, because the restriction of raw material, in its product, the kind of aliphatic acid formation is unreasonable, and is not ideal enough on performance.
We know, the harm of waste oil is very large, are class municipal refuses in the urgent need to address at present, and utilization of the present invention oil and fat preparation wherein becomes the fatty acid mixed collecting agent.The key technical problem that the present invention solves is to utilize the floatation process of the collecting agent of waste oil preparation for fluorite, play and reduce the double effects that pollutes and fully utilize, and promoting bargh to reduce beneficiation cost, the collecting agent of the present invention's preparation can obtain good index while being used for fluorite at normal temperatures.
Through consulting amount of literature data, use waste oil as the fatty acid mixed of raw material preparation as collecting agent research report also at present.The collecting agent that the present invention prepares take waste oil as raw material is functional, the existing a lot of defects of collecting agent of the prior art have been overcome, can substitute existing fatty acid collecting agent, and application of the present invention can take full advantage of the waste oil of threatening environment and food security, also realized the comprehensive regulation to environment.
Summary of the invention
The invention provides the method for a kind of collecting agent of the preparation take waste oil as raw material to fluorite, the method comprises the step of the collecting agent of the preparation take waste oil as raw material to fluorite, and wherein collecting agent prepares by the hydrolysis of waste oil.
That abandon when waste oil generally refers to the processed food such as hotel, restaurant, factory, family and discarded edible oil and fat discharging, be commonly called as hogwash fat, swill oil, also comprise the oil slick that enters in sewer, cesspool, or repeatedly decoct, exploded the grease (old oil) etc. of food.
Preferably, the preparation of collecting agent comprises the steps:
(a) waste oil is carried out purification;
The reaction that is hydrolyzed of the waste oil of the purification that (b) a step is obtained, namely obtain the collecting agent as the flotation mineral.
In the preparation method of above-mentioned collecting agent, selective hydrolysis is macromolecule alkali for hydrolysis, and preferable reaction temperature is 50-90 ℃, and the reaction time is preferably 30-90 minute.
In said method, basic hydrolysis is preferably NaOH or potassium hydroxide hydrolysis.The consumption of alkali is preferably the 1-5% of waste oil quality.
Preferably, the preparation of collecting agent comprises the steps:
The waste oil of purification is hydrolyzed, and reaction temperature is 50 ℃-90 ℃, and the reaction time is 30-90 minute, after hydrolysis finishes, resulting hydrolysate is cooling, use the organic extract liquid extraction, it is unsaponifiable matter at the middle and upper levels, lower floor is saponified; Take off the saponified of layer and add a certain amount of acid solution, making fatty acid mixed in product and the mass ratio of mixing-in fat hydrochlorate is 1: 0.1-10.
