The wet-process sludge phosphoric acid is used as the raw material, and is used as the pH regulator in reverse flotation of phosphorite. After the flotation process, the flotation index of the phosphorite meets the requirement on production of the wet-process phosphoric acid through a dihydrate method. The wet-process sludge phosphoric acid used as the pH regulator in the reverse flotation of phosphorite, disclosed in the invention, is simple in process and high in applicability, realizes the technique of mineralizing and coupling of the phosphorus chemical industry and flotation of phosphorite, and is of great significance for both the resources and the environmental protection.
Description
Technical field
The present invention relates to a kind of light phosphoric acid of phosphoric acid by wet process is used for phosphate reverse flotation pH regulator.Belong to phosphorous chemical industry and phosphorus ore choosing
Ore deposit production field.
Background technology
China's phosphate rock resource enriches, and the reserves of rock phosphate in powder occupy the second in the world, are only second to Morocco.Although China's rock phosphate in powder
Gross reserves it is very big, but great majority belong to middle and low grade bauxite, in ore contain a large amount of impurity, be that typical difficulty selects low activity
Phosphorus ore species.Phosphoric acid by wet process is the important intermediate products for producing phosphate products, is phosphorous chemical industry, metallurgy, medicine, food, military project
Important source material is provided etc. industry.Phosphorus ore is mainly for the preparation of phosphoric acid by wet process.
Used as medium adjustment, Main Function is sulfuric acid used in current phosphate rock floating：(1) slurry pH is adjusted.Due to
The pH value of ore pulp often directly or indirectly affects the floatability of its Minerals, so often adding regulator in floatation process
Change and adjust the floatability of various mineral.Under certain flotation conditions, mineral can be floated and are referred to as with the pH lines of demarcation that can not be floated
Critical pH；(2) the effect activity of other medicaments is adjusted.Medicament is had an effect with mineral surfaces, is that some of medicament is living
Property ion (or molecule).When the timing of dosing one, the content of the medicament ion in ore pulp is decided by the pH value of ore pulp again；(3)
Eliminate the impact to flotation harmful ion.Often containing many " unavoidable ions ", great majority soluble-salt in ore in ore pulp
Dissociation, also have from water for industrial use and medicament.Their impacts to flotation are more complicated, and existing activation, inhibitory action also have
Can consume various medicaments.To eliminate its impact, typical media regulator is acted on therewith, generates insoluble chemical compound precipitation to disappear
Except it；(4) adjust the dispersion of sludge and reunite.Thin sludge often makes different mineral particles without selectively reuniting, and destroys flotation
Selectivity, reduce concentrate quality, and make valuable mineral be wrapped in floc sedimentation to be easy to run off in mine tailing.
Phosphate reverse flotation is adopted using sulfuric acid as regulator, exist tank diameter in phosphate rock floating device, flotation device and
All there is calcium sulfate scaling in ore pulp pipe, especially water return pipeline fouling is very serious.Knot calcium reduces pipeline section product, increase
Flow resistance, while these dirty things provide breeding environment well for bacterium, accelerates the corrosion rate of transport pipeline, shortens
Life-span of pipeline.Production process usually causes damp production because of fouling, affects production, increases cost.Can using phosphoric acid slag acid
Avoid tying the appearance of calcium problem.
The content of the invention
The invention reside in overcoming prior art not enough, there is provided one kind utilizes gypsum stack backwater for phosphate reverse flotation pH
Regulator, realizes phosphorous chemical industry and phosphate rock floating mineralising coupling technique, with very big economic benefit.
The present invention is completed by following method：The light phosphoric acid of phosphoric acid by wet process is used for phosphate reverse flotation pH regulator, and it is special
It is that in a wet process the light phosphoric acid of phosphoric acid is raw material to levy, in delivering to phosphate rock floating regulator groove, as the pH regulators of phosphate reverse flotation.
Jing after a step reverse floatation process, phosphate rock floating index reaches the requirement that two water thing methods produce phosphoric acid by wet process.
Described 1 ton of phosphorus concentrate of every flotation needs slag field 5～15kg of backwater.
F≤0.1% in the light phosphoric acid of described phosphoric acid by wet process, SO4 2-≤ 1.0%, MgO≤0.5%.
Working mechanism；For a long time phosphorus ore all adheres to different technical fields separately from phosphorous chemical industry, and both sides are with phosphorus concentrate as technology
Technical research and technical and economic evaluation are carried out in node, segmentation, and to improve phosphorus ore grade, reduction impurity is mesh for front end phosphorus ore selecting and purchasing
Mark, by scouring or flotation concentrate is obtained.Rear end prepares fertilizer or other phosphorus chemical products according to concentrate chemical composition.And phosphorus ore
And it is how effectively solving waste water, waste residue and waste gas are asked that the sustainable development of phosphorus chemical industry needs the problem one that solves
Topic, two is to improve phosphoric acid extraction concentration, reduces subsequent concentration load and alleviates scale problems.
The present invention mainly returns extraction tank using the light phosphoric acid of phosphoric acid by wet process, on the one hand reduces phosphoric acid extraction concentration, increases dense
Contracting load, on the other hand impurity increases enrichment process fouling in light phosphoric acid.The present invention has process is simple, and strong applicability is realized
Phosphorous chemical industry and flotation of phosphate rock mineralising coupling technique, are all significant from resource or environmental angle.
Specific embodiment
The present invention is that in a wet process the light phosphoric acid of phosphoric acid is raw material, for phosphate reverse flotation pH regulator.Jing after floatation process, phosphorus
Ore deposit floatation indicators reach the requirement that two water thing methods produce phosphoric acid by wet process.
Invention utilize the light phosphoric acid of phosphoric acid by wet process to be used for phosphate reverse flotation pH regulator, on the one hand avoids what light phosphoric acid brought from asking
Topic；On the other hand process costs are significantly reduced.
