Abstract
The invention discloses a treatment technology of a copper leached solution. The treatment technology comprises the following steps: pumping the copper leached solution into a storage tank of a liquid purification factory; electrodepositing the copper leached solution to obtain electrodeposited copper, namely black copper; after removal of electrodeposited copper, evaporatively crystallizing and centrifuging the copper leached solution to obtain nickel sulfate; and after removal of electrodeposited copper and nickel sulfate, returning the remaining black acid, namely 30% dilute sulphuric acid, into a precious metal workshop so as to be used for copper leaching. By virtue of the technology, the recovery rates of copper and nickel are increased, wherein the recovery rate of copper is increased from 80% to 96% and the recovery rate of nickel is increased from 50% to 92%; the black acid can be recycled, so that the value of molten copper per cubic meter is enhanced and neither environment-friendly slurry nor externally-discharged wastewater is generated.
Description
Technical field
The present invention relates to a kind of novel process of processing copper leached solution, belong to copper technical field of smelting.
Background technology
Enterprise, before extracting precious metal with copper leached solution, process copper leached solution, reclaims copper and mickel, by original technique, processes, and reclaiming the copper obtaining is copper sponge, produces environmental protection mud, and sewage also will be arranged outward, has serious environmental issue.
Summary of the invention
The object of the invention is to provide for the deficiencies in the prior art a kind for the treatment of process of new copper leached solution.
The treatment process of copper leached solution of the present invention comprises:
(1) copper leached solution is pumped into Jing Ye factory storage pond;
(2) copper leached solution is carried out to electrodeposition process processing, obtaining electro deposited copper is black copper;
(3) copper leached solution of removing electro deposited copper is carried out to evaporative crystallization centrifugal, obtain single nickel salt;
(4) remove nigrotic acid remaining after electro deposited copper and single nickel salt the dilute sulphuric acid of 30% concentration turn back to precious metal workshop and divide copper to use.
Beneficial effect of the present invention: use technique of the present invention, the rate of recovery of copper, nickel is improved, copper is raised to 96% by 80%, and nickel rises to 92% by 50%, can reuse nigrotic acid, therefore can make every side's copper water rise in value approximately 300 yuan, and not produce environmental protection mud and efflux wastewater.
Accompanying drawing explanation
Fig. 1 is the skeleton diagram of the treatment process of copper leached solution of the present invention.
Embodiment
