Abstract
The invention provides a rare earth mineral collecting agent, which consists of the following raw materials in parts by weight: c5-970-90 parts of hydroximic acid; 5-15 parts of methylene blue; c11-165-15 parts of alkane kerosene. The rare earth mineral collector has the advantages of good selectivity, wide pH application range and strong collecting capability.
Description
Technical field
The invention belongs to mineral floating field, be specifically related to a kind of rare-earth mineral collector.
Background technology
At present along with mineral resources are continually developed utilization, resource is increasingly exhausted, rare-earth mineral grade is low and mineralogical property is complicated, in order to improve rare-earth mineral separating effect, improve dressing rare-earth ore index, increase economic benefit and the social benefit of enterprise, seek a kind ofly to rare-earth mineral collecting agent selectively, have important practical significance.
At the Rare Earth Mine collecting agent that at present occupies leading position in rare earth floatation process, there are oleic acid, oleate soap, hydroximic acid, hydroximic acid soap, oxidized paraffin wax soap, tall oil, tall oil soap, sub-blue etc. beauteously, wherein sub-orchid is that coco-nut oil fatty acid and methylglycine condensation are synthetic beauteously, and general structure is:
The problems such as above-mentioned collecting agent is used separately and has poor selectivity, dosing is large, chemical feeding points is many, produce bad operation, and the rate of recovery is low, and the rare earth ore concentrate grade selected is not high, make resource can not get good utilization.
Summary of the invention
The object of the present invention is to provide a kind of selectively good, pH is applied widely, collecting ability is strong, rare earth ore concentrate is of high grade rare-earth mineral collector.
Technical scheme of the present invention is:
A rare-earth mineral collector, is comprised of the raw material of following weight proportion: C
5-9hydroximic acid 70-90 part; Sub-blue 5-15 part beauteously; C
11-16alkane kerosene 5-15 part.
Preparation technology is as follows: successively by the C in above-mentioned raw materials
5-9hydroximic acid, Ya Lan and C beauteously
11-16alkane kerosene joins in agitator, mix and blend 0.5～1.5h.
Described rare-earth mineral is a kind of in parisite, monazite, strontium sulfate cerium ore deposit, xenotime.
Described C
5-9hydroximic acid, C
11-16alkane kerosene and beauteously sub-blue preferably technical pure.
Above-mentioned a kind of rare-earth mineral collector, in mineral floating operation, flotation pulp pH=9～11 o'clock, dosage is at 80-120g/t, the selective and strong collecting ability all having had.
A kind of rare-earth mineral collector of the present invention is black liquor, is slightly soluble in water.Its mechanism of action is C
5-9hydroximic acid and sub-blue beauteously, comprises a plurality of polar groups, can adsorb rare-earth mineral; Again with C
11-16the combination of alkane kerosene, produces cooperative effect, according to the composite composite drug forming of this principle, is adsorbed on mineral surfaces, first C by amalgamation mechanism, common adsorption mechanism
5-9hydroximic acid and sub-ly blue beauteously adsorbs at mineral surfaces, then by with C
11-16alkane kerosene non-polar group forms hydrophobic region, thus the hydrophobic floating of mineral, thus reached selective collecting.
The weight proportion scope of a kind of rare-earth mineral collector raw material of the present invention and each raw material, determines by lot of experiments.Combinations thereof and weight proportion scope can be given full play to cooperative effect, selectively good, collecting ability is strong, especially rare-earth mineral is had to good collecting effect, all there is good collecting effect pH values of pulp scope 9～11 o'clock, can effectively improve the rare-earth mineral rate of recovery and grade that flotation obtains.
