Problems solved by technology

[0003] Due to the above-mentioned particularity and difference of complex nickel-containing wet materials, it has become a difficult problem in the current smelting treatment and recovery technology; traditional enterprises select one kind of complex nickel-containing wet materials for separate treatment, and through appropriate processes, some metals can be recovered. Recycling; however, it is more difficult to process the mixed materials, and the processing capacity cannot be increased, which affects the processing efficiency of enterprises

Embodiment

[0043] The invention provides a method for producing agglomerates from complex nickel-containing wet materials, comprising:

[0044] S1. Ingredients:

[0045] The material containing 1% nickel, the material containing 3% nickel, the material containing 5% nickel, and the material containing 7% nickel are respectively mixed according to the ratio of 1:2:2:3 to obtain the complex nickel-containing wet material. The nickel content is 4.75%; then the complex nickel-containing wet materials and reagents such as coke powder, cement, and iron powder are mixed according to the proportions of 5%, 8%, and 10% of the total amount of materials, and are carried out in batches by forklift. The material is evenly mixed for the first time, and then the material is shoveled into the batching bin, automatically metered and fed to the biaxial mixing agitator for mixing, and the nickel-containing material after mixing continues to enter the granulation process according to the production plan of ...

Abstract

The invention discloses a method for producing agglomerates from complex nickel-containing wet materials, comprising: ingredients: mixing complex nickel-containing wet materials with coke powder, cement, and iron powder to perform aging interpenetration reaction to obtain premixed aging ingredients ; Granulation: Send the premixed aging ingredients into a granulator for granulation to obtain granular materials with a particle size of 30-50 mm; Sintering: Send the granular materials into a sintering furnace for sintering to obtain sintered blocks. The method of the invention can produce high-strength massive nickel-containing materials, creating favorable conditions for subsequent smelting and recovery of valuable metals to improve production efficiency and reduce production costs.

Description

technical field [0001] The invention relates to the technical field of nickel-containing material treatment, in particular to a method for producing sintered blocks from complex nickel-containing wet materials. Background technique [0002] In recent years, large-scale non-ferrous metal smelting enterprises will inevitably produce low-concentration nickel-containing copper and other metal tailings when producing high-purity nickel-copper and other metal products. All kinds of nickel-containing materials produced by solid separation measures; due to the wide variety of material output processes, the uneven water concentration of materials due to different filtration equipment, and the large differences in the viscosity of materials produced by different processes, it is impossible to Carry out direct landfill treatment; therefore, according to environmental protection requirements and corporate recovery rate needs, it is necessary to recycle complex nickel-containing wet mate...
