Like Fig. 1, shown in Figure 2, leach still according to the pressurization of the embodiment of the invention, comprising: kettle 10, feed-pipe 20, extraction line 30, a plurality of distance piece 40 and conducting element 50.
Particularly, be limited with in the kettle 10 and leach space 11, to carry out the leaching of ore pulp.
Feed-pipe 20 is arranged on a side of kettle 10, and is communicated with leaching space 11, so that in leaching space 11, mineral aggregate is provided.
A plurality of distance pieces 40 are established in the kettle 10 along leaching directions with arranging successively, and the lower space that will leach space 11 is divided into a plurality of leachings chamber 12, and ore pulp can leach chamber 12 internal reactions successively, and in the end one is leached 12 reaction backs, chamber from extraction line 30 discharges.
Conducting element 50 is arranged on the distance piece 40; And be communicated with adjacent two and leach chambers 12; Conducting element 50 imports in next leaching chamber 12 along the ore pulps that the leaching direction will go up in the leaching chamber 12; Conducting element 50 has inlet 51 and outlet 52, and the height of inlet 51 and outlet 52 all is lower than the height of conducting element 50 corresponding intervals parts 40, leaches among the chamber so that ore pulp can import to next through conducting element 50 before covering distance piece 40.As shown in Figure 2, the position of conducting element 50 on distance piece 40 is the lowest part of distance piece 40 end faces.
Still is leached in pressurization according to the embodiment of the invention; Distance piece 40 is provided with conducting element 50; Being provided with of conducting element 50 can avoid ore pulp directly to go into next leaching chamber 12 from 12 overflows of last leaching chamber; Under the constant condition of autoclave effective volume, can effectively prolong and respectively leach the reaction times that ore pulps are leached in pond 12, improve leaching efficiency.
As shown in Figure 1, according to one embodiment of present invention, the height of a plurality of distance pieces 40 can reduce along leaching direction successively, thus, can make things convenient for ore pulp to move to leaching direction through conducting element 50, prevents that ore pulp from diffusing out from the top of a plurality of distance pieces 40.
As shown in Figure 2, according to one embodiment of present invention, conducting element 50 can be the conduit of vertical direction setting; And 51 the height of entering the mouth is lower than the height of outlet 52, and for example, conduit can attach on the sidewall that is arranged on distance piece 40; For example; Each conducting element for example is a conduit, can be arranged on the same side of each dividing plate 40.Each conduit can conduit the lower end have opening, be inlet 51, upper end closed is provided with outlet 52 on the sidewall of upper portion side wall near distance piece 40 of conduit, correspondingly, on the correspondence position of distance piece 40, also be formed with hole.Ore pulp can get into next leaching pond 12 from exporting 52 from entering the mouth 51 entering.Conduit can be arranged side by side for many, so that the discharge of ore pulp strengthens, the speed of circulation is faster.
As shown in Figure 1, according to one embodiment of present invention, further comprise whisking appliance 60; Whisking appliance 60 can be located at the top of kettle 10, and with convenient control and installation, it has to the stir shaft that extends below 61; The bottom of stir shaft 61 is provided with stirring rake 62, and stirring rake is positioned at and leaches pond 12, and the speed of the stirring rake of whisking appliance 60 controls can be at 200～250rpm; For example can be 225rpm, ore pulp is stirred fully.Thus, stirring rake 62 can stir the ore pulp that leaches in the pond 12, also makes to leach to react more abundant.Preferably, the height of stirring rake 62 is lower than the height of inlet 51 and outlet 50.Thus, stirring rake 62 can stir the ore pulp that leaches in the pond 12 and 51 gets into next and leach pond 12 from entering the mouth.
Preferably, in the leaching chamber 12 at feed-pipe 20 places, the height of feed-pipe 20 is higher than the height of stirring rake 62.So that mineral aggregate enters among this leaching chamber more rapidly.And in the leaching chamber 12 at extraction line 30 places, the height of extraction line 30 is higher than the height of stirring rake 62.So that leaching the chamber 12 from this more fast, ore pulp discharges.
