Description
Technical field
The utility model belongs to hydrometallurgy chemical field, relates in particular to a kind of high ferro alloy treatment equipment.
Background technology
High iron alloy is that a kind of iron content obtaining through pyrometallurgical smelting is not less than 3%, also contains wherein alloy or the metallic compound of one or more valuable metal such as copper, nickel, cobalt.The object of processing this kind of raw material is, by valuable metal separating-purifying wherein, to obtain corresponding metal or salt series products.
The key issue of high iron alloy wet processing is to remove foreign metal Fe in the process of purifying in metal separation.Prior art is first alloy fragmentation to be obtained to thinner alloy powder, in acidic medium solution, leaches, and makes whole soluble metal compositions in alloy enter solution with ionic forms, and particularly impurity iron also all enters leach liquor.Leach liquor enters Cu extraction and electrolytic system afterwards, obtains standard cathode copper products.The remaining liquid of extraction Cu must, through entering cobalt extracting system except after Fe, obtain Co salt, Ni product salt after the separation of purifying.The shortcoming of above-mentioned traditional treatment method is, the one, and in alloy, cupric sulfide composition can not leach completely, and the direct yield of copper is low; The 2nd, because the Fe in alloy enters solution with ionic forms, increase the consumption of copper extractant; The 3rd, enrichment in electrolytic solution, reduces current efficiency of copper electrowinning; The 4th, from raffinate, deironing need to consume a large amount of alkali and oxygenant and the energy, and deironing cost is very high.
Utility model content
The purpose of this utility model is the problem existing for prior art, and a kind of high ferro alloy treatment equipment is provided.
Above-mentioned purpose realizes by following proposal:
A kind of high ferro alloy treatment equipment, is characterized in that, described equipment comprises displacement still (1), Oxidation Leaching still (2), pressure filter (3), filtrate receiver (4), Winning cell (5) and cobalt extraction box (6); The outlet end of described displacement still (1) is by being connected to the liquid feeding end of described Oxidation Leaching still (2) with the pipeline of pump, the outlet end of described Oxidation Leaching still (2) is by being connected to the liquid feeding end of described pressure filter (3) with the pipeline of pump, the outlet end of this pressure filter (3) is connected to the liquid feeding end of described filtrate receiver (4), the outlet end of this filtrate receiver (4) is by be connected to the liquid feeding end of described Winning cell (5) with the pipeline of pump, and the outlet end of this Winning cell (5) is connected to the liquid feeding end of described displacement still (1) and cobalt extraction box (6) by pipeline.
The beneficial effects of the utility model: 1) removed in traditional technology copper extraction, solution purification iron removal step, obviously shortened technical process, reduced artificial, auxiliary material and power consumption, reduced materiel machining cost.2) technical process of the present invention, because flow process is short, pass key control index is few, and the continuous and stable that is conducive to produce moves, and quality product is easy to control.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, high ferro alloy treatment equipment of the present utility model comprises displacement still 1, Oxidation Leaching still 2, pressure filter 3, filtrate receiver 4, Winning cell 5 and cobalt extraction box 6.The outlet end of displacement still 1 is by being connected to the liquid feeding end of Oxidation Leaching still 2 with the pipeline of pump, the outlet end of Oxidation Leaching still 2 is by being connected to the liquid feeding end of pressure filter 3 with the pipeline of pump, the outlet end of pressure filter 3 is connected to the liquid feeding end of filtrate receiver 4, the outlet end of filtrate receiver 4 is by be connected to the liquid feeding end of Winning cell 5 with the pipeline of pump, and the outlet end of Winning cell 5 is connected to the liquid feeding end of displacement still 1 and cobalt extraction box 6 by pipeline.
After the electrodeposition that high iron alloy powder returns with copper electrodeposition system, liquid reacts in still 1 in displacement, makes the Cu in liquid after electrodeposition
2+there is replacement(metathesis)reaction with Fe in alloy, make in alloy powder most Fe with Fe
2+form enters solution, and Cu in solution
2+be converted into simple substance Cu powder.After the supplementary a certain amount of acid of reacted alloy and solution, enter Oxidation Leaching still 2 and be oxidized selectively leaching.Make the valuable metal such as Cu, Co, Ni in alloy enter solution with ion kenel, Fe precipitates with the scum form of pyrrhosiderite or hydrous iron oxide.Completing solid-liquid separation through pressure filter 3 obtains purer oxidation scum and sells outside directly, directly do not enter Winning cell 5 containing the sulfate liquor such as copper, cobalt of Fe and carry out electrodeposition, obtain standard cathode copper, liquid circulation Returning equipment 1 after most of electrodeposition, to utilize sulfuric acid and concentrating cobalt and nickel.Cobalt in the electrolytic solution of Winning cell 5 is enriched to after certain concentration, containing liquid after cobalt electrolysis, carries out deep electrolytic decopper(ing) in the recycle system independently by equal amount open circuit part.Cobalt sulfate solution after electrolysis decopper(ing), enters cobalt extraction box 6 after removing sulfuric acid or regulating pH, obtains pure cobalt salt, nickel salt solution, to produce cobalt salt, nickel salt product.
