Description
Technical field
The present invention is a kind of lead zinc flotation tailing Waste water treatment medicament based on Chemical Manufacture, belongs to technical field of beneficiation.
Background technology
World's led-zinc-silver deposit is relatively abundanter, and lead-zinc ore can be divided into sulfide ore, mixed ore and oxygen by degree of oxidation
In the lead-zinc ore in change ore, China or even the world, lead-zinc sulfide ore stone and mixed ore account for the overwhelming majority, lead-zinc sulfide ore stone
Beneficiation method with mixed ore is mainly floatation, and a large amount of new water is consumed in lead zinc floatation process, in order to effectively will
Useful metal sorts out, and needs that a large amount of floating agent is added in different operation, mainly there is collecting agent, foaming agent, organic
With inorganic activator, inhibitor, dispersant etc., these medicament primary attachments are in concentrate, and other remaining medicaments are with tailing
It is transported to Tailings Dam and carries out self-purification.Nevertheless, the decomposition product of part metals ion, suspended matter, organic and inorganic medicament
Matter etc. all remains in milltailings solution, forms the tailing water containing a large amount of harmful substances, direct emission will be to ring
Border causes seriously to pollute, and influences lead zinc mineral processing index when recycling again, when the such waste water of conventional process, uses a variety of medicines
Agent removes harmful constituent respectively, and various medicaments only have single effect, cannot be harmful to two or more in waste water
Component removes simultaneously, and cost for wastewater treatment is high, complex process.
Invention content
In view of the deficienciess of the prior art, it is an object of the present invention to provide a kind of lead zinc flotation tailing based on Chemical Manufacture
Waste water treatment medicament, to solve the problems mentioned in the above background technology.
To achieve the goals above, the present invention is to realize by the following technical solutions：It is a kind of based on Chemical Manufacture
Lead zinc flotation tailing Waste water treatment medicament, is made of following raw material：It is calcium carbonate, diesel oil, calcium hydroxide, sodium carbonate, potassium carbonate, non-
Polyacrylamide, zinc sulfate.
Further, raw limestone is calcined and generates lime and carbon dioxide, added water digestion lime and generate milk of lime,
Then it is passed through carbon dioxide again, carbonization milk of lime generates precipitation of calcium carbonate, is most made in raw material through dehydration, drying and crushing afterwards
Calcium carbonate.
Further, ammonia and water and carbon dioxide reaction generate the ammonium hydrogen carbonate of a molecule, then by ammonium hydrogen carbonate with
Sodium chloride reaction generates sodium bicarbonate precipitation and ammonium chloride adds the sodium bicarbonate of generation through sodium bicarbonate solid is obtained by filtration
Thermal decomposition generates the sodium carbonate in raw material.
Further, zinc or crude zinc oxide materials and effect of sulfuric acid will be contained, obtain thick solution of zinc sulfate, through potassium permanganate oxidation,
Impurity is removed, zinc powder is then added, then agitated removing nickel, copper, cadmium impurity carry out secondary oxidation, to remove with potassium permanganate
Manganese and iron are removed, refined solution of zinc sulfate is obtained, through refined solution of zinc sulfate, is acted on soda ash liquid and generates basic zinc carbonate,
46 DEG C of controlling reaction temperature, PH6.8, free alkali 0.4%~0.5%, double decomposition obtains pasty material, to pasty material press filtration, filter cake
It is dry at 100 DEG C, until moisture 2.5% hereinafter, finely ground again, sieving, is made the zinc carbonate in raw material.
Further, featured to press 1 with water by lime stone after being sintered into calcium oxide：The ratio of (3~3.5) digests, raw
At the purified separation slagging-off of calcium hydroxide feed liquid, then through centrifugal dehydration, the drying at 150~300 DEG C, then screen in raw material
Calcium hydroxide.
Further, the potassium hydroxide solution obtained after potassium chloride being electrolysed, is carbonized in carbonators with carbon dioxide, warp
Saleratus is filtered to obtain in multi-effect evaporator evaporation, then through calcining the potassium carbonate being made in raw material.
Beneficial effects of the present invention：A kind of lead zinc flotation tailing Waste water treatment medicament based on Chemical Manufacture of the present invention,
Solve that metallic wastewater intractability is big, and processing cost is higher, and actual motion operates comparatively laborious problem, has and quickly removes
Calcium removes the multi-efficiencies such as oil removal and precipitation of heavy metals ion, and treated, and waste water had both met GB8978-1996 rows up to standard
Put standard.
Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
The present invention provides a kind of technical solution：A kind of lead zinc flotation tailing Waste water treatment medicament based on Chemical Manufacture, by
Following raw material is constituted：Calcium carbonate, diesel oil, calcium hydroxide, sodium carbonate, potassium carbonate, non-ionic polyacrylamide, zinc sulfate.
Raw limestone is calcined and generates lime and carbon dioxide, digestion lime is added water and generates milk of lime, then lead to again
Enter carbon dioxide, carbonization milk of lime generates precipitation of calcium carbonate, the carbonic acid in raw material most is made through dehydration, drying and crushing afterwards
Calcium.
Ammonia generates the ammonium hydrogen carbonate of a molecule with water and carbon dioxide reaction, then reacts ammonium hydrogen carbonate with sodium chloride
Sodium bicarbonate precipitation and ammonium chloride are generated, through sodium bicarbonate solid is obtained by filtration, the sodium bicarbonate heat resolve of generation generates
Sodium carbonate in raw material.
Zinc or crude zinc oxide materials and effect of sulfuric acid will be contained, obtain thick solution of zinc sulfate, through potassium permanganate oxidation, remove impurity,
Then zinc powder is added, then agitated removing nickel, copper, cadmium impurity carry out secondary oxidation with potassium permanganate, to remove manganese and iron,
