Abstract
A process for preparing zinc and indium from the In contained high-Fe zinc sulfide ore concentrate includes such steps as grinding, mixing with the waster electrodeposition liquid of Zn to obtain slurry, loading in pressurizing reactor, acid extracting for extracting Zn by more than 99% and In by more than 92%, neutralizing and depositing to separate In, removing Fe from the extracting liquid, solution cleaning, electrodeposition, and fusion-casting to obtain Zn.
Description
Technical field
The invention belongs to the smelting process that contains the indium zinc sulfide concentrates, more particularly, relate to a kind of smelting process of from contain the indium high-iron zinc sulfide concentrate, extracting the zinc indium.
Background technology
Contain the indium high-iron zinc sulfide concentrate be meant iron content more than 10%, contain zinc be lower than 48% and association has higher scattered metals indium, the general name of the class zinc sulfide concentrates that iron can't be removed in ore dressing process.At present, for the processing that contains this class material of indium high-iron zinc sulfide concentrate, usually adopt traditional " fluidized bed roasting-calcining high temperature peracid leaches " technology, indium from iron vitriol slag or and slag in reclaim, the sulfur dioxide flue gas that high-iron zinc sulfide concentrate produces in roasting process reclaims through relieving haperacidity, but in sulfuric acid oversupply area, particularly there are not sour industrial area of consumption and traffic low developed area, the sulfuric acid that the sulfur dioxide flue gas that is produced by the roasting zinc sulfide concentrates reclaims, be subjected to having a strong impact on of sulfuric acid market, cause sulfuric acid to be difficult to effective utilization.Therefore, there is significant limitation in " roasting-leaching " smelting process.
In addition, there are defectives such as extraction of indium solution temperature height, solution-treated amount are big in the Technology of " the direct extracting and separating indium of pressurized acid leaching-leach liquor handle contain the indium high-iron zinc sulfide concentrate extract the metallic zinc indium " developed, this technology.
Summary of the invention
The present invention has overcome the deficiency of existing zinc ore concentrate smelting process, and what provide that a kind of smelting process do not produce that sulfur dioxide gas, extraction of indium liquor capacity greatly reduce contains indium high-iron zinc sulfide concentrate smelting process.
Realize that step of the present invention is: (1) contains the indium high-iron zinc sulfide concentrate and sulfur acid 140g/L～170g/L zinc electrodeposition waste liquid is sized mixing with fine ground, add in the autoclave then, 140 ℃～160 ℃ of controlled temperature, pressure 1.0MPa～1.6MPa, directly lead to the oxygen acidleach, valuable metals such as the zinc in the concentrate, indium, copper, cadmium are efficient simultaneously to be leached, and sulphur, lead, silver etc. are then stayed in the slag; (2) infusion solution of output is leached in pressurization, after 85 ℃～90 ℃ reduction is handled down, carries out the neutralization precipitation indium with zinc sulfide concentrates; (3) the precipitation of indium slag dissolves with sulphuric acid soln, with P204+ kerosin extraction of indium, back extraction indium from organic phase, the back extraction indium aqueous solution with zinc metal sheet replace the sponge indium; (4) leach liquor after the precipitate and separate indium adopts deironing in the Zinc hydrometallurgy process, solution purification, electrodeposition, founding operation, the output metallic zinc.Wherein: contain the indium high-iron zinc sulfide concentrate and contain indium 0.025%～0.09%, iron content 10%～25% contains zinc 38%～48%.Pressurized acid leaching is one section or two sections pressure leaching methods.
Beneficial effect of the present invention is: directly enter autoclave and lead to the oxygen acidleach because of containing indium high ferro zinc sulfide ore, the extraction temperature height, directly leach zinc, indium in the concentrate with the sulfuric acid in the zinc electrodeposition waste liquid, with the roasting in existing " roasting-leaching " technology, gather dust, leach and concentrate on pressurization and finish in the leaching process, make work simplification, process intensification is realized containing the efficient of indium zinc sulfide concentrates and is directly leached; Simultaneously, the sulphur in the concentrate is converted into elementary sulfur, after maturation process such as flotation, hot melt filtration are handled, obtain being convenient to the sulfur product that stores and transport, so main process is not subjected to the influence of sulfuric acid market and communications and transportation.Infusion solution separates indium through neutralization precipitation, the anti-molten and extraction of heavy indium slag, and the extraction solution treatment capacity significantly reduces, and has reduced production cost.
