Abstract
The invention discloses a recycling method for mineral processing waste water with high leaching residue content in zinc hydrometallurgy. In the recycling method, a P204 extract phase is used to extract zinc-bearing solution; waste electrolyte in a zinc-metallurgical electrolysis system is used to reextract a P204 organic extraction phase to allow zinc in the P204 organic extraction phase to enter the waste electrolyte; and reextraction solution returns to a zinc hydrometallurgy leaching system after deoiling. In the recycling method, zinc sulphide concentrate is added to the mineral processing waste water with mineral processing reagent content exceeding 200mg/L after filtration treatment to be mixed for primary adsorption; and the zinc sulphide concentrate can effectively absorb aerofloat in the mineral processing waste water and remove excessive mineral processing reagent from the mineral processing waste water. The zinc recycled by the recycle method can be conveniently applied to the existing facility; the reextraction solution can directly return to the zinc hydrometallurgy leaching system after the deoiling; the process produces no pollution; the recyclable zinc metallicity can be increased; and better economic benefit is achieved.
Description
Technical field
The invention belongs in the zinc hydrometallurgy the recycle method of beneficiation wastewater, relate to the recycle method that the zinc hydrometallurgy height soaks slag beneficiation wastewater specifically.
Background technology
Annually in Zinc hydrometallurgy process all can produce a large amount of height and soak slag, height soaks valuable metals such as argentiferous in the slag, zinc, lead, copper, because valuable metal content is low, the valuable metals such as silver in the slag soak to high in enterprise, adopt floatation process to reclaim.And in floatation process, can produce a large amount of beneficiation wastewater, and through being carried out assay, beneficiation wastewater draws, and the zinc content in the beneficiation wastewater is 16g/l～18g/l, and relative amount is higher, has recovery value.All be beneficiation wastewater to be advanced Sewage Disposal carry out being recycled after the neutralisation treatment in the prior art, but this way of the prior art not only can cause the loss of the zinc in the beneficiation wastewater, also can increase the processing cost of beneficiation wastewater.
Containing a large amount of beneficiation reagents in the beneficiation wastewater, all is only to adopt active carbon that beneficiation reagent is adsorbed in the prior art, but when the beneficiation reagent content in the ore dressing waste water surpassed 200mg/L, the adsorption effect of active carbon just was not very desirable.How a kind of new adsorbent can be provided, can better adsorb beneficiation reagent unnecessary in the beneficiation wastewater, the zinc recovery that makes beneficiation wastewater is higher.
Summary of the invention
The present invention is in order to overcome the deficiency that prior art exists, and a kind of with low cost, recycle method that zinc hydrometallurgy height that zinc recovery is higher soaks slag beneficiation wastewater is provided.
The present invention realizes through following technical scheme: a kind of zinc hydrometallurgy height soaks the recycle method of slag beneficiation wastewater, and it comprises the steps:
A, at first beneficiation wastewater is carried out filtration treatment, make solid content in the beneficiation wastewater less than 10ppm;
B, the beneficiation wastewater that surpasses 200mg/L through beneficiation reagent content after the filtration treatment is added zinc sulfide concentrates stir and carry out one-level absorption, remove the beneficiation reagent in the beneficiation wastewater;
C and then process charcoal absorption are handled, and further remove the beneficiation reagent in the beneficiation wastewater;
D, use P
204Extractant is to carrying out extraction process through the zinc-containing solution after zinc sulfide concentrates and the charcoal absorption in extraction tank;
E, in extraction process, add a small amount of caustic soda,, form P to regulate extraction yield as required
204Extracted organic phase and raffinate;
F, with the electrolysis waste solution in the zinc metallurgy electrolysis system to P
204The extracted organic phase processing of stripping makes P
204Zinc in the extracted organic phase gets into electrolysis waste solution and forms strip liquor;
Turn back to zinc metallurgy after g, the strip liquor of handling through stripping are handled through de-oiling and leach system;
H, handle the back through the raffinate of extraction process through de-oiling and get into the flotation beneficiation system usefulness of sizing mixing, add in the process of sizing mixing in the lime and unnecessary acid;
I, the beneficiation wastewater of discharging through the flotation beneficiation system get into the waste water filtering pond, and beneficiation wastewater carries out recycle again.
Beneficiation reagent is black powder and foaming agent, and foam is many in the concentrate pulp, and beneficiation reagent is also more relatively, filters this part beneficiation wastewater of back and directly squeezes into the ore dressing blended size system, does not get into extracting system, contains the high beneficiation wastewater of beneficiation reagent with minimizing and gets into extracting system.
The appropriate design extraction tank, minimizing is carried secretly, and sets up secondary clarifier, and prolonging settling time is to reduce organic facies to get into the major measure that leaches operation.When iron in organic facies run up to a certain degree after, need make organic facies viability again to organic facies with hydrochloric acid solution back extraction iron.
The present invention utilizes P
204Extraction phase extracts zinc-containing solution, utilizes electrolysis waste solution in the zinc metallurgy electrolysis system to P
204Extracted organic phase is stripped, and makes P
204Zinc in the extracted organic phase gets into electrolysis waste solution, and strip liquor leaches system through turning back to zinc hydrometallurgy after the de-oiling.The organic facies recycle turns back to the flotation beneficiation system usefulness of sizing mixing again after the raffinate de-oiling.
The invention has the beneficial effects as follows: the present invention adds the zinc sulfide concentrates stirring to the beneficiation wastewater that surpasses 200mg/L through beneficiation reagent content after the filtration treatment and carries out one-level absorption; Zinc sulfide concentrates can adsorb the black powder in the beneficiation wastewater effectively, can remove beneficiation reagent too much in the beneficiation wastewater.The present invention can further improve the comprehensive recovery levels of enterprise; The metallic zinc that reclaims can easily use in the existing facility, and strip liquor can directly turn back to the zinc hydrometallurgy electrolysis system through after the de-oiling, and technology is pollution-free; Increase recyclable zinc amount of metal, favorable economic benefit is arranged.Technology of the present invention is ripe, and the effect that reclaims zinc is better, with low cost, can turn back to the flotation beneficiation system after the raffinate de-oiling again and size mixing and utilize non-wastewater discharge again.
