Description
Technical field
The present invention relates to a kind of continuous extraction apparatus, be particularly useful for the extraction of laboratory copper mine bacteria leachate mineral bacteria leachate.
Background technology
Bacterial leaching can be divided into leaching, extraction and electrodeposition three phases.Extraction is exactly a difference of utilizing metal ion bonding force in various different solvents, it is separated concentrating, and produces highly purified metal to carry out electrodeposition.Mostly adopt now separating funnel to carry out the extraction of one-level one-level ground in the laboratory, can not operate continuously, can't enlarge experimental size, and percentage extraction is not high yet yet.
Summary of the invention
In order to overcome the deficiency of existing extraction plant, the invention provides a kind of continuous extraction apparatus to mineral bacteria leachate.
A kind of continuous extraction apparatus to mineral bacteria leachate comprises three extraction tanks, is respectively one-level extraction tank, secondary extraction tank and reextraction groove, and wherein one-level extraction tank placement direction is opposite with reextraction groove placement direction with the secondary extraction tank; Each extraction tank is divided into mixing section, three parts in clarifying chamber and separate chamber; The separate chamber UNICOM of the mixing section of one-level extraction tank and secondary extraction tank, the mixing section UNICOM of the separate chamber of one-level extraction tank and secondary extraction tank and reextraction groove; The opposite side of secondary extraction tank mixing section and the separate chamber UNICOM of reextraction groove.
The extraction tank two ends are respectively mixing section and separate chamber, the centre is the clarifying chamber, mixing section is divided into two-layer up and down by the dividing plate at about 1/5～1/6 place, distance bottom, there are two opening for feeds in lower floor, be respectively extraction agent and leach liquor (or strippant and load organic phases) opening for feed, the upper strata is a hollow gear formula stirring rake, under the stirring rake, there is a circular aperture in baffle plate central authorities, liquid stirring under the negative pressure that produces, enters the mixing section upper strata by aperture after entering the mixing section bottom, mixing section has a top cover, and the direct-current machine that links to each other with stirring rake is installed.Mixing section and intermediary dividing plate top, clarifying chamber are porose, enter clarifying chamber's clarification layering in the hole thus at the mixed liquid of mixing section.The separate chamber is made of three baffle plates, the baffle plate adjacent with the clarifying chamber, two ends are all unsettled up and down, the lower end is connected support with second baffle plate, second baffle plate lower end is unsettled to be connected with first baffle plate, and the top links to each other with separate chamber's top cover, and the lower end of the 3rd baffle plate is connected the bottom of separate chamber, the upper end is unsettled, and is lower than first baffle plate.
The present invention can large-scale continuous the bacteria leachate of extraction mineral, control is convenient, and can regulate mixture strength according to the practical situation of extraction agent and leach liquor, can realize very high extraction efficiency, and adopt counter-current extraction and reextraction to combine, saved extraction agent.It is main raw that the present invention adopts synthetic glass, can tolerate the acid attack of leach liquor, be applicable to the sour environment of this experiment, hollow gear formula stirring rake rotates the negative pressure that produces makes liquid enter mixing section, and can realize very high mixing efficiency, two different baffle plates of height make the weight two-phase be able to good separation before and after the separate chamber, and can avoid the generation of third phase.
Description of drawings
Fig. 1 is a connection diagram of the present invention.
Fig. 2 is the vertical view of extraction tank of the present invention.
Fig. 3 is the A-A sectional view of Fig. 2.
The present invention is further illustrated below in conjunction with accompanying drawing.
Embodiment
Adopt apparatus of the present invention that China's Mine Cu ore bacteria heap leaching testing campaign leach liquor is carried out extraction experiments.The various constituent concentrations of this feed liquid are respectively (g/L): Cu 1.12, Fe 0.74, Zn 3.53, pH2.22.Extractant concentration is 5%, and thinner is a sulfonated kerosene, and strippant is 180g/L H
2SO
4Solution.Other reaction conditionss are: mixing time 4min, compare (O/A) 2: 3, balance pH2.5.The percentage extraction of final copper reaches more than 98%.Extraction process is as follows:
This device is made up of three extraction tanks, adopt counter-current extraction and reextraction principle of combining, leach liquor is through one-level extraction tank 1, secondary extraction tank 2 and being extracted in the load organic phases, extraction agent is then entered by secondary extraction tank 2, becomes the load organic phases of carrying metal ion after one-level extraction tank 1 flows out, in reextraction groove 3, lose metal ion, be reduced, continue to enter the secondary extraction tank, repeatedly recycle.Extraction agent and leach liquor are entered by the opening for feed 5,6 of one-level extraction tank mixing section 4 respectively, after mix the mixing section bottom, the adjustable speed numeral of installing on cover plate 7 shows under the drive of direct-current machine 8, hollow gear formula stirring rake 9 rotates and forms negative pressure, liquid enters the upper strata by aperture 11 in the middle of the dividing plate 10, enter clarifying chamber 13 by cinclides 12, liquid is farthest mixed.In clarifying chamber 13 after the layering, enter 14 upper stratas, the separate chamber baffle plate 15 that gently overflow mutually, flow out by hole 16, lower floor's heavy phase then flows through from baffle plate 15 and 17 bottoms, and the baffle plate 18 that overflow flows out by hole 19.The flow direction of light phase is shown in single arrow line among Fig. 1 in the extraction process, and the flow direction of heavy phase is shown in double arrowed line among Fig. 1.
