Abstract
The invention relates to a method for recovering cobalt and copper from cobalt-copper-iron alloy. The method comprises the following steps: preparing the cobalt-copper-iron alloy into 100-mesh or below cobalt-copper-iron alloy powder; then, after mixing the alloy powder with a fluxing agent and a slagging constituent, carrying out thermal treatment by microwaves, wherein the temperature of thermal treatment by microwaves is 1200-1450 DEG C, the microwaves used are from a high temperature microwave oven, so that the cobalt-copper-iron alloy is segregated to generate copper and a cobalt-iron alloy; after casting the melted alloy, quickly cooling to form an alloy ingot, wherein the cooling speed is not lower than 30 DEG C/s; and after crushing the alloy ingot into 200-300 meshes, and quickly dissolving cobalt and iron by a diluted acid so that cobalt and iron are separated from copper, wherein cobalt and iron can be separated by adopting conventional chemical methods.

Background technology
Fast development along with world economy, the particularly fast development of battery functi on material, superfine powdery material and superhard material, cause the consumption of relevant nonferrous materials also at rapid growth, particularly China very lacks and the swift and violent cobalt resource of the whole world consumption impetus.
The application of microwave heating in metallurgy is the metallurgical technology that developed recently gets up, experimental results show that: microwave heating can accelerating oxidation nickel, cobalt oxide and the prereduction of manganese oxide ore before leaching, can promote roasting and the chlorination of moly-sulfide and sulfuration rhenium, the metal of nearly all industrial use can be processed with microwave.Microwave heating is used to the fragmentation of ore, the pre-treatment of refractory gold ore, reclaim gold, extract rare metal and the carbothermic reduction of heavy metal, iron ore and vanadium titano-magnetite, the processing of industrial waste etc. from low grade ore and mine tailing from ore.
Summary of the invention
The object of this invention is to provide a kind of method that reclaims cobalt copper from cobalt-copper-iron alloy, with the valuable element in efficient recovery copper ferrocobalt alloy, alleviate China's cobalt resource imbalance between supply and demand.
The present invention is achieved by the following technical solutions:
A method that reclaims cobalt copper from cobalt-copper-iron alloy, comprises the following steps:
Cobalt-copper-iron alloy is made to 100 orders or following cobalt-copper-iron alloy powder;
After powdered alloy being mixed with fusing assistant and slag former, adopt microwave to heat-treat, it is 1200-1450 ℃ that microwave thermal is processed treatment temp again, and microwave used is high temperature microwave stove, makes ferro-cobalt copper alloy produce segregation and generates copper and ferro-cobalt; By cooling fast after liquation casting, speed of cooling is not less than 30 ℃/sec, becomes alloy pig;
Alloy pig is after being crushed to 200-300 order, and by the quick dissolved cobalt of diluted acid, with iron and separated with copper, it is separated that cobalt and iron can adopt conventional chemical process to carry out.
Cobalt-copper-iron alloy powder passes through Mechanical Crushing, or passes through medium-frequency induction furnace or mineral hot furnace or electric arc furnace through about 30 minutes, after 1300-1500 ℃ of fusing, utilizes high pressure gas or high-pressure water mist to change into 100 orders with thin powdered alloy.
Described fusing assistant and slag former comprise one or more in sodium-chlor, Repone K, sodium carbonate, sodium sulfate, S-WAT, SODIUMNITRATE, calcium carbonate, calcium oxide, magnesiumcarbonate or magnesium oxide, and adding weight percent is 3-15%.
Described diluted acid dissolves fast, and the acid of employing is that any two kinds of its molar concentration rates of combination in dilute sulphuric acid, dilute hydrochloric acid, rare nitric acid are 1: 1-1: 3, and after mixing, the volumetric concentration of diluted acid is less than 50%; Diluted acid solvent temperature is 50-100 ℃, and dissolution time is 4-8 hour.
The invention has the beneficial effects as follows:
The comprehensive cobalt metal reclaiming in cobalt-copper-iron alloy, simple for process, suitability for industrialized is produced.
