Description
Technical field
The present invention relates to Mineral Processing Engineering field, particularly one is used for bauxite forward flotation adjusting agent and using method thereof, belongs to comprehensive utilization of resources engineering.
Background technology
China's bauxite resource belongs to diaspore type bauxite mostly, and wherein alumina silica ratio is greater than the high-quality bauxite ratio of 7 seldom, and the diaspore type bauxite alumina silica ratio of more than 80% is all less than 7, and the bauxite of alumina silica ratio 3-5 accounts for the overwhelming majority.This part resource must carry out desiliconization, enrichment and upgrading by beneficiation method, makes alumina silica ratio be greater than 7, thus can meet the Minimum requirements of lime-Bayer process.Floatation is the main method of ore dressing and desiliconizing, and direct flotation the most successful current a kind of bauxite floating method beyond doubt.During bauxite forward flotation, according to the essential mineral compositing characteristic of diaspore type bauxite, adopt sodium carbonate as pH values of pulp adjusting agent, adopt waterglass, calgon, Quadrafos etc. as the adjusting agent of aluminium silicate mineral, adopt oxidized paraffin wax soap or enuatrol as collecting agent, diaspore in ore and rich intergrowth are selected, thus realizes the flotation desilication of bauxite.
In bauxite forward flotation process, in the Selective depression of the siliceous minerals such as kaolinite, pyrophillite, illite and ore pulp, the elimination of unavoidable ion plays decisive role by the direct flotation of bauxite.The effect of adjusting agent efficiently suppresses siliceous mineral and eliminates unavoidable ion impact, do not cause suppression again to diaspore simultaneously.
At present, mainly use waterglass, calgon, Quadrafos etc. as the adjusting agent of siliceous mineral in bauxite forward flotation, these adjusting agents also can play the effect of reacting with unavoidable ion simultaneously.But the major defect of these adjusting agents is: large usage quantity, also inhibitory action is had to diaspore, particularly under large consumption condition, often stronger to the suppression of diaspore, thus cause the decline of the Al2O3 rate of recovery, simultaneously the adjusting agent such as calgon is completed by complexing the elimination of unavoidable ion in ore pulp, often needs to consume a large amount of calgons, effect is also general, thus causes direct flotation effect general.
Summary of the invention
In order to overcome above defect, the invention provides a kind of for bauxite forward flotation adjusting agent and using method thereof, apply the present invention to, in bauxite direct-flotation desiliconisation technique, the selective inhibitory to siliceous mineral can be strengthened, strengthen unavoidable ion (Ca simultaneously
2+, Mg
2+deng) elimination ability, improve the effect of bauxite forward flotation.
For realizing above object, the technical solution adopted in the present invention is: a kind of for bauxite forward flotation adjusting agent, it is a kind of modified phosphate, and main component is hydroxy ethylene diphosphonic acid potassium or hydroxy ethylene diphosphonic acid sodium, and its structural formula is:
A kind of using method for bauxite forward flotation adjusting agent, when carrying out bauxite forward flotation, the bauxite Milling product granularity character of alumina silica ratio 3-5 accounts for 80-90% for-0.074mm grade, the pH value of flotation system controls at 9-11, using enuatrol as collecting agent, consumption is 500-1200g/t, and adjusting agent consumption of the present invention is 60-70g/t.
Further, when new inhibitor consumption is 60g/t, for the bauxite of alumina silica ratio 4-5, product granularity character accounts for 80%-85% for-0.074mm grade, and the basicity of flotation system controls as pH=10-11, and take enuatrol as collecting agent, consumption is at 800-1200g/t.
Further, the described consumption for bauxite forward flotation adjusting agent is 60g/t.
Further, the pH value of described flotation system is 10.
Further, the consumption of described collecting agent enuatrol is 700g/t.
Beneficial effect of the present invention: 1, the present invention's one is used for bauxite forward flotation adjusting agent, a kind of modified phosphate, containing multiple modified phosphate foundation group in the molecular structure of its main component.The functional group of novel adjusting agent sodium phosphate (potassium) is multiple modified phosphate root functional groups, its dissolubility is extremely strong, the transparent yellow liquid of outward appearance, it is by after organic composite modification, the Molecular Geometries of phosphate radical changes, thus chelation can be there is with aluminium silicate mineral surface, and greatly strengthen selective inhibitory, then general to the inhibitory action of diaspore;
Employing the present invention suppresses the aluminium silicate mineral in bauxite, by efficient chelating inhibitory action, the aluminium silicate minerals such as kaolinite, illite, pyrophillite can be suppressed by effective as selective, unavoidable cation in ore pulp can be eliminated efficiently on the impact of flotation effect simultaneously, promote effectively being separated of diaspore and siliceous mineral.
2, multiple modified phosphate root functional group is contained in its molecular structure while, these functional groups can directly and the cation such as Ca2+, Mg2+ react, considerably increase the elimination ability to unavoidable ion in ore pulp, effectively can eliminate the impact of unavoidable ion, thus improve the effect of bauxite forward flotation.
3, to the bauxite of alumina silica ratio about 3-5, when other process conditions are identical, after adopting the present invention, compared with conventional adjusting agent calgon, concentrate alumina silica ratio 1-2 can be improved, improve Al
2o
3rate of recovery 10-20%.
