Embodiment 1

[0022] Take 100 kg of cobalt-copper-iron alloy, quench it into 150-mesh alloy powder by high-temperature and high-pressure water, then put the alloy powder into a rotary kiln for oxidation and roasting at 1200°C for 10 hours, and then put the roasted alloy material into a vibration mill Mechanical activation was carried out for 80 minutes to obtain alloy powder with an average particle size of 100 microns. Get 100g of alloy powder after mechanical activation, control the solid-liquid ratio to be 1: 10, control the pH value at 3.0 during the reaction, stir and react at 50°C for 8 hours, filter and wash, analyze the cobalt-copper-iron content in the filtrate and slag. The one-stage leaching rate of cobalt is 90.11%, the one-stage leaching rate of iron is 100%, and the copper is basically not leached. Then 20 g of the leaching residue was directly dissolved with 5 mol / L sulfuric acid, the solid-liquid ratio was controlled to be 1:6, and the reaction was stirred and reacted at 100...

Embodiment 2

[0024] Take 100 kg of cobalt-copper-iron alloy, quench it into 30-mesh alloy powder by high-temperature and high-pressure water, then put the alloy powder into the rotary kiln for oxidative roasting at 500°C for 6 hours, and then put the roasted alloy material into the vibration mill Mechanical activation was carried out for 20 minutes to obtain alloy powder with an average particle size of 200 microns. Get 100g of alloy powder after mechanical activation, control the solid-liquid ratio to be 1:5, control the pH value at 1.5 during the reaction, stir and react at 100°C for 10 hours, filter and wash, analyze the cobalt, copper and iron content in the filtrate and slag. The one-stage leaching rate of cobalt was 87.31%, the one-stage leaching rate of iron was 99.65%, and copper was basically not leached. Then 21.16g of the leaching residue is controlled to a solid-liquid ratio of 1:5, directly dissolved with 1mol / L sulfuric acid, stirred and reacted at 50°C for 10 hours, and the ...

Embodiment 3

[0026] Take 100 kg of cobalt-copper-iron alloy, quench it into 80-mesh alloy powder by high-temperature and high-pressure water, then put the alloy powder into the rotary kiln for oxidative roasting at a temperature above 600°C for 6 hours, and then put the roasted alloy material into the vibration mill The machine was mechanically activated for 20 minutes to obtain alloy powder with an average particle size of 10 microns. Get 100g of alloy powder after mechanical activation, control the solid-liquid ratio to be 1: 10, control the pH value at 0.5 during the reaction, stir and react at 70°C for 2 hours, filter and wash, analyze the cobalt, copper and iron content in the filtrate and slag. The one-stage leaching rate of cobalt was 84.96%, the one-stage leaching rate of iron was 99.24%, and copper was basically not leached. Then use 5g of sodium chlorate as an oxidant for 22g of the leaching residue, control the solid-liquid ratio to 1:8, add sulfuric acid dropwise to keep the pH...

Abstract

The invention discloses a method for processing a cobalt-copper-iron alloy, which comprises the steps of pre-processing, first-stage leaching, second-stage leaching, and purifying and deironing with leaching solution. The method of the invention has the advantages of simple process, low production cost and high recovery rate of the metal cobalt.

Description

technical field [0001] The invention relates to a method for treating cobalt-copper-iron alloys. Background technique [0002] Cobalt-copper-iron alloy is the converter slag obtained during converter blowing during the copper or cobalt smelting process, and then the alloy slag containing cobalt, copper, iron and other elements enriched by electric furnace sulfur production and reduction smelting. Due to the color of the material It is white and slightly yellow when it is fresh, and it is customarily called white metal. With the rapid development of the world economy, the demand for cobalt materials is growing rapidly. With the increasing scarcity of cobalt resources, countries with large cobalt resources, such as the Democratic Republic of the Congo and Zambia, have introduced relevant policies such as strict restrictions on the export of cobalt ore in recent years, which has led to a sharp rise in the price of cobalt in the world. Therefore, the method of extracting cobal...
