In addition, generally the copper ore concentrates source of copper smelting enterprise buying is all wider, complicated component, it is various that copper is smelted in dirty acid contained valency metal species, there are copper, lead, arsenic, zinc, antimony, selenium, bismuth, silver etc., and wherein copper, arsenic are main component, other valuable metal content is larger with the variation fluctuation range of copper ore concentrates, and this has caused valuable metal Comprehensive Recovery Technology difficulty large to a certain extent.
Utility model content
The purpose of this utility model is to provide a kind of copper to smelt dirty sour valuable metal comprehensive recovery device, copper is smelted in dirty acid the metals such as copper, lead, arsenic, zinc, antimony, selenium, bismuth, silver, rhenium, comprehensively reclaims, and improves comprehensive utilization of resources rate.
For this reason, the utility model adopts following technical scheme:
A kind of copper is smelted dirty sour valuable metal comprehensive recovery device, comprise the dirt acid pump, the first pressure filter, retort, reaction liquid pump and the second pressure filter that connect successively, and the top of described retort is connected with the first pressure filter, bottom is connected with reaction liquid pump, steam heating coil and whipping appts are installed in described retort, and the top of described retort is also connected with reagent pot by volume pump.
Further, in described retort, be also connected with temperature measuring equipment, for monitoring the temperature of reaction in retort.
The beneficial effects of the utility model are: the utility model apparatus structure is simple, and flow process is short, less investment, and running cost is low; Utilize the utility model device can make copper smelt the precipitated metal rate of recovery such as copper, rhenium, silver, bismuth in dirty acid and reach more than 90%, the valuable metal in dirty acid is reclaimed with sedimentary form, efficiently solve the loss of valuable metal in dirty acid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The dirty sour pump of 1-, 2-the first pressure filter, 3-retort, 4-reacts liquid pump, 5-the second pressure filter, 6-volume pump, 7-reagent pot, 8-steam heating coil, 9-whipping appts, 10-temperature measuring equipment.
Embodiment
As shown in Figure 1, a kind of copper is smelted dirty sour valuable metal comprehensive recovery device, comprise the dirt acid pump 1, the first pressure filter 2, retort 3, reaction liquid pump 4 and the second pressure filter 5 that connect successively, and the top of retort 3 is connected with the first pressure filter 2, bottom is connected with reaction liquid pump 4, steam heating coil 8 and whipping appts 9 are installed in retort 3, the top of retort 3 is also connected with reagent pot 7 by volume pump 6, is also connected with temperature measuring equipment 10 in retort 3.
Utilize the utility model Recovering Copper to smelt the process of valuable metal in dirty acid as follows:
The copper of processing smelt dirty sour sulfur acid 80-120g/l, cupric 60-200g/l, containing arsenic 2-5g/l, leaded 2-30mg/l, bismuth-containing 200-500mg/l, rhenium-containing 20-60mg/l, argentiferous 2-20mg/l, concrete steps are as follows:
(1) copper is smelted to dirty acid and delivered in the first pressure filter 2 and carry out press filtration through the sour pump 1 of dirt, except the solid particulate matter in decontaminated acid, filtrate enters retort 3, and filter residue is mainly plumbous mud, is transported to plumbous smelting system and reclaims plumbous;
(2) hypo solution that is 10-20% in the interior configuration quality percentage concentration of reagent pot 7, by volume pump 6, the hypo solution in reagent pot 7 is added in retort 3, controlling hypo solution add-on is that every cubic metre of filtrate adds 5-10kg hypo solution, and the add-on of hypo solution can be controlled by volume pump 6; Then in steam heating coil 8, pass into steam so that the interior reaction solution of retort 3 is heated, Heating temperature is 60-70 ℃, opens 9 pairs of reaction solutions of the interior whipping appts of retort 3 and continues to stir, and the rotating speed of controlling whipping appts 9 is 80-120r/min;
(3) after the interior solution reaction 30-45min of retort 3, finish reaction, solution after reaction is sent in the second pressure filter 5 and carried out press filtration by reaction liquid pump 4, filtrate is discharged after neutralizing treatment, and filter residue adopts corresponding extract technology successively the copper in filter residue, rhenium, silver, arsenic, lead to be leached respectively to recovery.
In above-mentioned steps (3), filter residue is mainly the throw out of the metals such as cupric (Cu), rhenium (Re), silver (Ag), arsenic (As), and filtrate enters follow-up dirty acid treatment operation, and in retort, the reaction principle of solution is as follows:
