Abstract
The invention discloses a method for preparing a copper-iron nano plated layer from low-grade sulfide ore through direct electro-deposition. The method comprises the following steps: mixing choline chloride and urea in a mole ratio of 1:2, and sufficiently stirring to uniformly mix choline chloride and urea; further adding excessive oxidized roasted sulfide ore powder, and stirring till the valuable metal phase in the roasted powder is completely dissolved in an ionic liquid; by taking an acid activated square titanium sheet as a cathode and a platinum wire as an anode, controlling the temperature of electrolyte to be 80-100 DEG C, the applied voltage to be 1.8V and the electro-deposition time to be 5-7 hours; after electro-deposition is completed, taking out the cathode sheet, washing, and drying in the argon atmosphere at 80-90 DEG C, thereby obtaining a metal plated layer. The method is simple in device, short in procedure and green and environment as the nano metal plated layer is prepared by taking the low-grade oxidized and roasted sulfide ore as a metal source and enriching and extracting metal in the ore through electro-deposition in a choline chloride-urea ionic liquid system.
Description
Technical field
The present invention relates to a kind of metallic copper wet method preparation process, particularly the technique of copper is extracted in a kind of galvanic deposit, is applied to the Technology field that the green metallurgical comprehensive of mineral utilizes.
Background technology
Non-ferrous metal is the grand strategy resource of China, is the important substance basis of branch of industry's development such as aerospace, traffic, electronic information and energy industry.China's non-ferrous metals industry achieved remarkable achievement in recent years, non-ferrous metal ultimate production continuous 6 years the first in the world.Although China's colored metallurgical industrial achieves very big achievement, but still there is the problems such as Production Flow Chart length, complicated operation, energy expenditure be huge, seriously polluted.Country clearly proposes the Eleventh Five-Year Plan period domestic production of units total value energy consumption and reduces about 20%, and total emissions of major pollutants reduces by the binding indicator of 10%.So under the new situation how meet national economy high speed development to non-ferrous metal demand while on original basis, reduce energy consumption and decreasing pollution thing quantity discharged, become current green metallurgical electrochemistry and the instant task of environment-protecting industrial.
Sulphide ores is the topmost Mineral resources type of non-ferrous metal, but China's sulfuration Mineral resources 70% are low-grade many metal many ore deposits phase complicated ore, and utilizes along with the continuous exploitation of Mineral resources, the features such as Mineral resources forward is poor, assorted, difficult development.The contradiction that comprehensive resource utilization rate is low and non-ferrous metal demand is large is becoming increasingly acute.Complex multi-metal sulphide ore, its composition of ores is various, and the valency metal object of mainly containing is mainly chalcopyrite, pyrrhotite, pentlandite mutually, and each mineral are closely inlayed mutually, and disseminated grain size is thin.Therefore traditional method separation difficulty, main metal recovery rate is low.Chalcopyrite is the abundantest chalcopyrite ores of a kind of reserves, accounts for 70% of world's known copper ore reserves.Current copper smelting by pyrometallurgy remains in the highest flight, about has the copper of 75%-80% in the world by traditional " melting-blowing-refining-electrolysis " explained hereafter.But both at home and abroad along with the continuous exploitation of copper ore resource utilizes, ore grade is more and more lower, and environment protection has also caused the great attention of national governments, and some drawbacks of copper smelting by pyrometallurgy and deficiency have come out gradually.Copper-sulphide ores leaching is for many years the core of copper mine hydrometallurgy, mainly contains Roasting And Leaching, pressure leaching, potassium cloride, ammonia leaching and Bioleaching etc.Western developed country wet type copper smelting ratio increases year by year, and particularly " leaching-Extraction electrodeposition " technique brings technological revolution to Copper Processing Industry.Along with the reinforcement day by day of various countries' environmental consciousness, people more pay close attention to green and the Sustainable development of metallurgical industry.Wish the novel green hydrometallurgical processes can developing less energy-consumption, low acid consumption, hypoxemia consumption, non-pollutant discharge.
Day by day poor along with single metal mine resource, complex multi-metal mine will become the emphasis of mineral exploration and exploitation in the future.And the various metal content major part in complex multi-metal mine belongs to middle-low grade, adopt traditional pyrogenic process or hydrometallurgical technology to process, not only energy consumption is high, and metal separation weak effect.In-pulp electrolysis technology will become the first-selection of process multi-metal complex ore with its good metal separation effect.The concept that in-pulp electrolysis is proposes at 20 century 70s, the United States Patent (USP) about copper electrodeposition (US Pat:3464904) of E. C. Brace acquisition in 1969, and this is the report the earliest of relevant in-pulp electrolysis; 1975, J. C. Loretto achieved a United States Patent (USP) (US Pat:3926752), and this patent is pointed out, is separated in anolyte compartment and cathode compartment in an electrolyzer with ion-exchange membrane, by electrolytic recovery fine copper and metallic iron, and in-pulp electrolysis that Here it is.After this in-pulp electrolysis technology obtains research and apply widely, achieves plentiful and substantial achievement in research.In-pulp electrolysis technology has its salient feature: flow process is short, energy consumption is low, metal separation is effective, environmental protection.Today of and environmental requirement increasingly stringent day by day poor at single metallic mineral resources, in-pulp electrolysis has obvious advantage.Although the study mechanism of traditional in-pulp electrolysis achieves many progress, because its speed of reaction is slow, also do not find the method reducing energy consumption and increase economic efficiency at present, there is no absolute advantage economically compared with traditional copper metallurgy.
Ionic liquid is as a kind of novel reaction medium, possess the advantage of organic solvent and high-temperature molten salt simultaneously and become very promising low temperature " green " solvent, use it for non-ferrous metal extraction and isolation only to carry out in room temperature or close under room temperature, there is the features such as reaction conditions gentleness, energy consumption be low, pollution-free, significantly can reduce production cost, there is great potential.What in ionic liquid, carry out hydrometallurgy research is the people such as the McCluskey of University of Newcastle with ionic liquid [Bmim] BF

4be one of the most effective ionic liquid, and successful galvanic deposit is except the copper deposits of fine and close light.The applied research of recent ionic liquid in the field of metallurgy such as metal electrodeposition, metal ion extraction has achieved certain progress (Gali. Ski M; Lewandowski A; St ì pniak I. Ionic liquids as electrolytes [J]. Electrochemica Acta; 2006,51 (26): 5 567 – 5 580; Visser A E, Swatloski R P, Peichert W M, et al. Traditional Ex-tractions in Nontraditional Solvents:Groups 1 and 2 Extraction by Crown Ethers in Room Temperature Ionic liquids [J]. Ind. Eng. Chem. Res., 2000,39 (10): 3 596-3 604.).This shows that the green hydrometallurgy new technology that Cu settled layer is expected to be developed to a set of chalcopyrite zero release is prepared in Chalcopyrite Leaching galvanic deposit in ionic liquid, the problem that the environmental pollution that exists in non-ferrous metal extraction and isolation is serious can be solved simultaneously.
