Description
Technical field
The invention belongs to the underground metal mining field; Relate to organic method in a kind of recovery copper extraction throw out; Be specifically related to a kind of in the technological process of copper oxide ore hydrometallurgy production electro deposited copper; The extraction throw out that produces in extraction and the back extraction process is handled, to reclaim the method for organic phase wherein.
Background technology
When from copper oxide ore, extracting metallic copper, comparatively conventional method is: ore leaching-leach liquor extraction-anti-stripping agent electrodeposition gets electro deposited copper.Owing to have suspended particle, Sulfates and oxidizing substance etc. in the leach liquor; In extraction process; These materials easily flocculate, carry secretly, degrade with the organism generation; And form density is 0.8～1.05, and is suspended in the throw out on extraction liquid or the strip liquor liquid level, and the substrate that is deposited in extraction, reextraction bottom of device.Be suspended in the throw out on extraction liquid and the strip liquor liquid level, cause electric effusion impurity to raise, influence the electro deposited copper quality because of containing organic phase.Be suspended in the throw out of extraction liquid and strip liquor liquid level simultaneously, because of can not get efficient recovery, and be circulated to the leaching operation, thereby cause the mass consumption of extraction agent, thinner (kerosene etc.) with the surplus liquid of extraction.Be deposited in the substrate of extraction, reextraction bottom of device, can cause extracting afunction, directly influence the electro deposited copper quality.
The method that prior art is handled throw out has: 1) with behind the diatomite adsorption activation throw out, carry out spinning and obtain organic phase.Yet, because the zeyssatite price is high, more than 3000 yuan per ton, cause processing cost too high, enterprise can't accept.2) handle throw out with the natural subsidence method, organism is got in the supernatant and be convenient to reclaim, other material then is concentrated in the settling bowl bottom and regularly discharges and abandon.This method treatment time is long, takies big area land resources, and processing efficiency is low, and the organism loss of carrying secretly in the throw out is serious, is difficult to reduce production costs, improve the quality of products.
Summary of the invention
The present invention aims to provide organic method in a kind of recovery copper extraction throw out, solves prior art when handling copper extraction throw out, and the processing cost of existence is high, and enterprise is difficult to bear, and electric effusion impurity is high, influences problems such as electro deposited copper quality.
The present invention realizes through following technical proposal: organic method in a kind of recovery copper extraction throw out is characterized in that through following each step:
A, get the immature soil and dry, be crushed to granularity again less than 30mm, subsequent use;
B, will produce extraction throw out in the extraction liquid of electro deposited copper and salvage out after, sedimentation 24～30 hours obtains the organism on upper strata and the throw out of lower floor;
C, press the mass ratio of Sheng Tu ︰ throw out=1 ︰ 3～5, the steps A gained immature soil is joined in the step B gained throw out, mix to such an extent that mix thick mud, leave standstill to mixing in the thick mud and overflow organism.
D, with step C overflowed organism deposition 24～30 hours, the upper strata organism that obtains is from electro deposited copper extraction throw out and reclaims the organism that obtains.
The immature soil of said steps A is that to take from the gradient moderate, and soil property is thicker, does not have trees, and peels off the soil on 0.3～0.6m top layer.
The extraction throw out of said step B is that to use the aperture be that the nylon leaching net of 0.4～0.5mm is salvaged.
The upper strata organism that said step B obtains returns the extraction process that the copper oxide ore hydrometallurgy is produced electro deposited copper, is used for purification by liquid extraction copper sulfate.
Remaining mud shape thing entering tailing dam was stored up after said step C overflowed organism.
Can add the immature soil again if mixture is crossed when rare among the step C, guarantee that throw out all obtains handling; If add throw out during the mixture overdrying, guarantee that the immature soil makes full use of, organism is all reclaimed.
The extraction liquid of said production electro deposited copper is meant the extraction liquid of extraction process generation and the anti-stripping agent that the reextraction process produces; Specifically in following process steps, produce: 1) cupric oxide ore is carried out dump leaching of sulfuric acid liquid or agitation leach by routine, get leach liquor; When 2) leach liquor being extracted by ordinary method, obtain extraction liquid; When 3) stripping by routine again, obtain anti-stripping agent.
Throw out is when mixing stir process with the immature soil, and the moisture in the throw out has been destroyed the structure of throw out by immature soil extruding absorption; Make extraction agent and kerosene in the organic phase, do not overflowed, precipitate again afterwards by immature soil absorption; After 24～30 hours, small amounts of solid matter gets in the throw out, and the organic phase after the purification can be returned extraction process and use; The efficient recovery organic phase reduces extraction agent and thinner consumption, reduces production costs.
Advantage that the present invention possesses and effect: the present invention utilizes the throw out that produces with extraction behind the immature soil dryness in the sun to mix, and after making moisture film in the throw out be stirred extruding to break, water is wherein adsorbed by the immature soil; And organism is released and overflows, and through purifying post precipitation, organism returns extraction process and uses; To reduce extraction agent and kerosene unit consumption, avoid impurity entering electrodeposition flow processs such as iron ion, reduce the electrodeposition power consumption; Improved the electro deposited copper quality, effects of energy saving and emission reduction is good, and is good in economic efficiency.High efficiency, low cost of the present invention is handled the extraction throw out; Substitute expensive import zeyssatite processing scheme, efficiently solve the technical problem of from sulphuric leachate, obtaining high-purity electro deposited copper, production cost is low; Extraction efficiency is high, has realized recovery, has purified organic purpose in the copper extraction throw out.
