Description
Technical field：
Chemical method removing calcium and magnesium is substituted present invention relates particularly to a kind of extraction removing calcium and magnesium
Method, belong to the technical field of chemical industry removing calcium and magnesium technique.
Background technology：
With regard to known to inventor, original chemical method removing calcium and magnesium technique is heated up using acid solution
More than 85 DEG C plus sodium fluoride removing calcium and magnesium, adjust pH value 4.5 or so, and press filtration is produced
Fluorination calcium and magnesium hazardous waste, it is necessary to be stored in Special slag, solution is used after removing calcium and magnesium
Upper extraction line between sulfuric acid readjustment pH value 3-3.5, the process steam consumption is big,
Sodium fluoride is added according to raw material calcium-magnesium content simultaneously, and extraction removing calcium and magnesium original is adopted
Calcium and magnesium is stripped with sulfuric acid, causes calcium sulfate precipitation to block extraction tank, while extracting work
The anti-ferrous acid that section is produced cannot be processed, and extractant consumption increases, and production cost increases.
The content of the invention：
The purpose of the present invention is exactly to overcome the above not enough, there is provided a kind of production cost
Reduce, do not produce hazardous waste to be fluorinated calcium and magnesium, raw materials consumption is few, product yield
Height, the extraction removing calcium and magnesium of product quality stabilization substitutes the side of chemical method removing calcium and magnesium
Method.
The present invention is achieved in that by the following technical programs, described extraction
Removing calcium and magnesium substitutes the method for chemical method removing calcium and magnesium it is characterized in that comprising the following steps：
Extraction removing calcium and magnesium adds sodium hydroxide saponification using P204 organic phases, according to P204
To the extraction yield and the relation of balance PH of various metals, pH value is adjusted, extraction
Series is controlled, the impurity such as extraction iron, zinc, calcium, manganese from cobalt solution, calcium,
Copper, manganese, zinc load enter organic phase, then again through persalt back extraction for calcium chloride,
Copper, manganese, zinc, solution, cobalt, nickel, magnesium enter raffinate, into next procedure,
Farther out, cobalt enters P507 load organic phases nickel to cobalt nickel defiber and magnesium enters raffinate
Liquid, load organic oppositing back-extraction turns into cobalt chloride solution.
Solution can be directly entered extraction by plate compression after Suan Rong workshop sections remove iron
Workshop section carries out separation, impurity removal, and extraction takes the sulfuric acid to carry out being stripped calcium slag, generates sulfuric acid
Calcium, it is calcium sulfate to use plate compression filter residue, pours into Ordinary solid waste slag,
The anti-molysite acid that extraction section is produced simultaneously need to return to Suan Rong workshop sections and be used, and transform
The anti-molysite acid of P507 cobalts nickel defiber first, cobalt section 0.5N is washed for P204 afterwards
Hydrochloric acid, the anti-molysite acid of P204, original 4N is instead of for anti-copper MnZn 4N hydrochloric acid
Sulfuric acid, anti-copper MnZn calcium and magnesium cell body is changed into hydrochloric acid system, raw without precipitation without blocking
Into calcium chloride copper MnZn liquid, liquid adds iron powder reducing to produce copper sponge, plate-frame filtering
Afterwards liquid add calcium oxide carry out precipitation generation hydroxide MnZn.Chemical method removing calcium and magnesium
Method is that the cobalt sulfate solution of Suan Rong workshop sections heats up more than 85 DEG C, plus sodium fluoride is removed
Miscellaneous, sodium fluoride presses 3 times of inputs of calcium-magnesium content in solution, then adds sodium carbonate regulation
PH value 4-4.5, then clarified by plate compression, then add sulfuric acid regulation pH value
3-3.5, upper extraction line carries out cobalt nickel separation, and the technique consumption of production cobalt chloride liquid is high,
The reduction of cobalt yield is caused containing 2% cobalt in fluorination calcium and magnesium slag simultaneously, fluorination calcium and magnesium is again
Hazardous waste, it is necessary to there is Special slag factory to store,
Compared with the prior art, the invention has the advantages that production cost reduction, former
Material consumption is few, reduces auxiliary material sulfuric acid, sodium pyrosulfite, sodium chloride, calcium oxide
Consumption few 25% or so, easily filtering, feed liquid are limpid, to extraction workshop section reaction, extraction
Groove is not easily blocked；Impurity is reduced, and product quality stabilization, product yield is high.
Specific implementation method：
With reference to embodiment, the present invention is described in further detail, described
Extraction removing calcium and magnesium substitute chemical method removing calcium and magnesium method it is characterized in that including with
Lower step：
1 original chemical method removing calcium and magnesium technique is heated up more than 85 DEG C using acid solution and adds fluorine
Change sodium removing calcium and magnesium, adjust pH value 4.5 or so, press filtration produces fluorination calcium and magnesium dangerous
Waste must be stored in Special slag, and solution adjusts back pH value with sulfuric acid after removing calcium and magnesium
Upper extraction line between 3-3.5, the process steam consumption is big, at the same sodium fluoride according to
Raw material calcium-magnesium content is added, and causes production cost to increase.
2 extraction removing calcium and magnesium techniques, Suan Rong workshop sections except after iron solution by sheet frame pressure
Filter can be directly entered extraction workshop section and carry out separation, impurity removal, and removing calcium with solvent extraction magnesium technique changes
Sulfuric acid is taken when entering to carry out being stripped calcium slag, causes calcium sulfate, is filtered using plate compression
Slag is calcium sulfate, pours into Ordinary solid waste slag, and the muscle power of manpower consumption at that time is big,
Extraction cell body is easily blocked, while the anti-molysite acid that extraction section is produced need to return to sour molten work
Duan Jinhang is used, and company is by modified technique, and P507 cobalts nickel defiber first is anti-
Molysite acid, cobalt section 0.5N hydrochloric acid is washed for P204, and the anti-molysite acid of P204 is used for
Anti- copper MnZn 4N hydrochloric acid instead of original 4N sulfuric acid, and anti-copper MnZn calcium and magnesium cell body becomes
It is hydrochloric acid system, without precipitation without blocking, generates calcium chloride copper MnZn liquid, liquid adds
Iron powder reducing produces copper sponge, and liquid adds the calcium oxide to carry out precipitation life after plate-frame filtering
Into hydroxide MnZn.
