Abstract
The invention discloses a recycling and treating method of nickel cobalt waste alloy material, which relates to a nickel cobalt waste alloy material treating process during the nickel cobalt recycling process of the nickel cobalt waste alloy material. The invention is characterized in that high grade nickel matte is generated by the air refining of the nickel cobalt waste alloy material, and then the nickel cobalt is recycled in the nickel cobalt production process. In the method of the invention, air refining high grade nickel matte is added in the nickel cobalt waste alloy in the later stage of air refining in a nickel tilting converter, and then the nickel cobalt recycling is performed. The recycling and treating method of the nickel cobalt waste alloy material has the advantages that the metal recovery ratio is high, the process is simple, and the cost is low.
Description
Technical field
A kind of recovery and treatment method of nickel cobalt waste material relates to the treating processes that a kind of nickel cobalt waste material reclaims the nickel cobalt waste material in the nickel cobalt process.
Background technology
Contain valuable metals such as metallic nickel, cobalt and tungsten in the nickel cobalt waste material.At present, the recovery and treatment method of nickel cobalt waste material has and uses earlier the thermal process concentration and separation, and then carries out method recovery nickel, cobalt and the tungsten of the step of acid dissolving leaching with the wet processing process.Its technical process is long, the processing cost height, and operational condition is poor.
Summary of the invention
Purpose of the present invention is exactly the deficiency of depositing at above-mentioned prior art, and the recovery and treatment method of a kind of nickel cobalt metal recovery rate height, technology is simple, cost is low nickel cobalt waste material is provided.
The objective of the invention is to be achieved through the following technical solutions.
A kind of recovery and treatment method of nickel cobalt waste material is characterized in that its recycling process is that nickel cobalt waste material blowing is generated high ice nickel, enters and reclaims the nickel cobalt in the nickel cobalt production process.
The recovery and treatment method of a kind of nickel cobalt waste material of the present invention is characterized in that nickel cobalt waste material blowing generates high ice nickel process and nickel cobalt waste material is added in the nickel converter blows.
The recovery and treatment method of a kind of nickel cobalt waste material of the present invention is characterized in that described nickel cobalt waste material bessemerizes the later stage at nickel and add, and the blowing temperature is 1200-1350 ℃, and duration of blast is 0.8～1.5 hour.
The recovery and treatment method of a kind of nickel cobalt waste material of the present invention is characterized in that described nickel cobalt waste material adds the 2%-5% of the weight blowing melt weight of nickel converter.
The recovery and treatment method of a kind of nickel cobalt waste material of the present invention, nickel cobalt waste material comprise useless nickel cobalt superalloy, useless magnet steel and magnet steel crumb, nickel cobalt expansion alloy, hard alloy scraps and spent catalyst etc.Because each element is Cu＜Ni＜Co＜Fe＜W＜Cr＜Mo＜V＜Mn＜Ta＜Nb＜Al to the size order of the avidity of oxygen in the alloy, in the alloy with the avidity of the oxygen Elements C o bigger, Fe, W, Cr, Mo, V, Mn, Ta, Nb, Al than nickel all with preferential oxidation.According to the avidity size, the order of element oxidation is undertaken by Al, Nb, Ta, Mn, V, Mo, Cr, W, Fe, Co, Ni, Cu in the converting process, before nickel is near complete oxidation, element al, Nb, Ta, Mn, V, Mo, Cr, W, Fe, Co etc. can both be by complete oxidations, and generate corresponding stable state oxide compound and quartzite slag making.
Method of the present invention, waste alloy of nickel cobalt is bessemerized the high ice of later stage adding blowing nickel at nickel, carries out the nickel cobalt again and reclaims.The recovery and treatment method of nickel cobalt metal recovery rate height, technology is simple, cost is low nickel cobalt waste material.
