Description
Technical field
The utility model relates to a kind of leach liquor gathering system that is used for dump leaching field, mine, and dump leaching field, particularly a kind of mine has the three-dimensional gathering system of leach liquor of bottom antiseepage.
Background technology
After exploitation for many years, the high grade ore in the mine of China is fewer and feweri, and the raising of nonferrous metal price makes low grade ore progress into the commercial value scope, and the metal of low grade ore is collected a lot of dump leaching modes that adopt; With the copper mine is example, and copper mine stone is built heap and formed the dump leaching field, adopts the dilute sulphuric acid of ability dissolution of metals to drip pouring on ore body, and sulphuric acid soln utilizes under the gravity and oozes; React gradually with copper mine stone, form the copper sulfate infusion solution, contain a large amount of cupric ions and unreacted sulfuric acid completely in the solution; Being valuable intermediates, if the solution seepage runs off, is the tremendous economic loss to enterprise not only; To also causing very big destruction in the natural ecological environment, therefore, the impervious lining of dump leaching field, mine is indispensable; It should be noted that the general bulky in stockyard, mine, the heap process of building is slowly piled according to the speed of digging the ore deposit and is built; One of a spray is built in similar paving brick, heap, advances one by one; 3～4 sprays are at the same time often arranged, and those go through the heap body that has sprayed one period then becomes the hillock body, is similar to people's life cycle.Because the speed of response characteristic of sulfuric acid and ore: beginning is fast, so the strength of solution of beginning is high, slow afterwards; Strength of solution decreases; Therefore the dump leaching field strength of solution of different times, different blocks is different, and concentration reaches certain value, then can be used for electrolysis and obtains metal product; Low concentration solution then is used to loop back spray, so enterprise can hope to obtain more high density leach liquor.
Traditional dump leaching field gasket construction often is arranged to the plane; Be the seepage prevention that adopts one deck clay to form on the highdensity Vilaterm of one deck (High Density Polyethylene is designated hereinafter simply as " the HDPE ") film, and in the heap body facility of any vertical collection leach liquor be not set as the auxiliary seepage proof layer; Relying on space between the ore let oozes under the solution; The shortcoming of this structure is: the solution of different times, different blocks flows in the liner plane and mixes, and causes the solution of high density to be diluted by low concentration solution, and actual available highly concentrated solution reduces on the contrary; In a word, collection effciency is low; Though the clay resist has the auxiliary seepage proof function on the film, make copper-containing solution become muddy, electrolytic metal product quality reduces.And the HDPE film seepage prevention layer safety assurance of individual layer is smaller; Simultaneously owing to must contain the powder of some fine ore and the disintegration in acidization in the ore; Form the mud layer that hardens along with oozing under the solution; Stop up the space between the ore gradually, even stop up drainage pipe, thereby make solution capacity gauge complete failure.
Summary of the invention
Being directed to existing clay class impervious lining, be prone to make leach to collect solution becomes muddy, and electrolytic metal product quality reduces and collection tube only is set in the bottom makes shortcomings such as can't obtaining more high density leach liquor.The utility model purpose is to provide a kind of three-dimensional gathering system of leach liquor that dump leaching field, mine has the bottom antiseepage that is used for; Can guarantee that dump leaching field, mine leach liquor can isolate fully with physical environment (underground water and subsoil earth), each unit leach liquor is carried out efficiently subregion collect; Particularly gabion vertical shaft and end metalling; The 3 D stereo gathering system that forms has improved the leach liquor capacity gauge of heap body greatly, thereby improves the output of dump leaching field highly concentrated solution; Increase the output of metal product, have good economic benefits.
The technical scheme of the utility model: a kind ofly be used for the three-dimensional gathering system of leach liquor that dump leaching field, mine has the bottom antiseepage; It is characterized in that comprising the branch separation levee, be positioned at clay seam, compound impervious barrier, coarse sands layer, the metalling of laying from the bottom to top successively the bottom, the HDPE pipe that is embedded in metalling intermediary tube wall belt hole, vertical gabion well spaced apart; Separation levee was divided into a plurality of unit with gathering system in said minute, vertically bury underground in the said gabion well tube wall belt hole HDPE pipe and be embedded in metalling intermediary HDPE pipe and link to each other.
As the optimal way of the utility model, said compound impervious barrier constitutes by laying antiseepage soil between the double-deck HDPE anti seepage membrane.The antiseepage soil of said compound impervious barrier is clay seam or bentonite bed.Said gabion well is made up of geotechnological grille network parcel rubble.Said gabion well diameter is 80～200cm.
The advantage of the utility model is:
1, two-layer HDPE film anti-seepage effect is outstanding; When one deck wherein suffers breakage, still can rely on another layer, and bentonite bed between the two membranes or clay seam has the function of automatic patching bugs; Make this compound impervious barrier have powerful antiseepage ability, the environment protection function is outstanding; Especially for the such bottom cushion in dump leaching field, mine, after ore was built heap, the antiseepage bed course promptly was under the state that can't repair, and the advantage of double-deck HDPE seepage prevention is outstanding;
2, the gabion vertical shaft collection tube that is provided with in the heap body is connected with the collection tube of bottom broken stone layer, has formed the compound gathering system of 3 D stereo, has improved the solution collecting effect of heap body greatly.
2 and the setting of zoning unit, after oozing under the leach liquor in favourable each unit, because the barriering effect of separation levee; Can only discharge by this unitary collection tube; Help partition management, the collection of solution in the unit, keep the output of the solution of high density as far as possible, improve metal product output.
3, the total system structural safety is reliable, good environmental protection, good in economic efficiency, and management maintenance simply waits to have and promotes the use value preferably.
