Abstract

The invention provides a flotation agent suitable for a foam flotation method of oxidized ores and nonmetallic ores. The agent can be used alone or mixed with other fatty acid collecting agents in the flotation process of oxidized ores and nonmetallic ores. The method has the advantages of low reagent dosage, high selectivity, low temperature resistance and wide applicable pH range, and particularly when the method is used for reverse flotation of fluorite from iron ore, the flotation recovery rate is improved by 4.8 percent. The flotation synthesis process is simple, stable in product performance, non-toxic, convenient and reliable to use and low in cost.

Description

A kind of flotation agent that is used for ore foam floatation
The invention belongs to ore froth flotation field, what relate to is a kind of collecting agent that is applicable to oxide ore and nonmetallic ore froth flotation.
At present, in oxide ore and nonmetallic ore froth flotation process, particularly when iron oxide ore, fluorite ore deposit or magnesite flotation, several floating agents commonly used mainly are that oleic acid, oxidation paraffin wax soap, tal fibre wet goods fatty acid collecting agent (are seen " Mineral Processing Technology " that B.A.Wills writes, Britain Pergamo publishing house, 1988, the 4th edition, P456).Perhaps one of above-mentioned fatty acid collecting agent is mixed use (see Russian Patent SU 1602578, October 30 nineteen ninety, application and Chinese patent CN 1032631A applied on September 17th, 1988) with other medicament.The selectivity of these medicaments is low, and is big to the sensitiveness of slurry pH and flotation temperature, and bad dispersibility, reagent consumption are big in faintly acid and low temperature ore pulp.Because the influence of above-mentioned these factors cause such medicament service condition harshness, and flotation effect is bad.
Fatty acid-based aryl sulfonic acid is a class surfactant.Though in textile industry, be used as (C.A.73:99934z such as making catalyst among dyeing auxiliaries, the grease water Jie, 1970 and C.A.75:112274x, 1971), but be used for the consonance agent that the ore foam flotation method is made flotation collector and made fatty acid collecting agent, both at home and abroad beyond example still.
The objective of the invention is to, it is strong to explore a kind of good dispersion, selectivity height, collecting ability, the collecting agent composition for flotation of coal that can use under the pH of broad value scope and low temperature.Perhaps this medicament is mixed use by a certain percentage with above-mentioned fatty acid flotation collector, to reach another best separating effect.
Particular content of the present invention is described below: at first with broken and fine grinding ore and water be modulated into ore pulp, add fatty acid-based arylsulphonate collecting agent 100~200 gram/tons then and give the ore deposit, after the stirred for several minute, add conventional foaming agent and adjust agent, again after the stirred for several minute, wherein purpose oxide mineral or nonmetallic mineral are also collected as the froth pulp emersion, but not the purpose mineral will be discharged as the deep gouge product.Wherein used fatty acid-based aromatic sulfonic acid salt accords with following molecular formula in this method:
In the formula: Ar is aryl or the aryl that replaced by one or more hydroxyls, halogen, ether, alkoxyl;
R 1, R 2Be respectively C 1-8, C 1-10Alkyl;
M is alkaline earth metal cation (K, Na).
Above-mentioned collecting agent except can using separately, also can with oleic acid, stearic acid, laurate, tall oil, oxidation paraffin wax soap, aphthenic acids by 0.5~1.5: 1 weight ratio is mixed use.
Collecting agent used in the ore floatation method of the present invention is compared with conventional fatty acid flotation collector, has following advantage:
1. good dispersion, collecting ability is strong, the selectivity height;
2. concentrate quality is good, the yield height of purpose mineral;
3. reagent consumption is low, and collector dosage is 70~150 gram/tons only, adjusts the agent consumption and reduces by 66~100%, and the inhibitor consumption reduces by 50~68%;
4. the flotation pH value wide ranges of Shi Yonging, mixed reagent can use about pH=3~10;
5. the flotation temperature of Shi Yonging is low, can use down at 5~10 ℃;
6. strong to water quality adaptability, can use the backwater in ore dressing plant;
7. synthesis technique is simple, is easy to control, grasps, and raw material sources are extensive, and properties of product are stable, and are nontoxic, and cost is low and easy to use.
Flotation collector or mixed reagent used in the inventive method are applicable to oxide ore and the use of nonmetallic ore flotation field.
