The recycling of nickel scraps is a complex but efficient process, which is mainly achieved through the following steps:
Raw material collection and classification
-
Source: Nickel recovery mainly comes from anode materials in electroplating tanks, nickel-hydrogen batteries, electronic components, electrolytic cells, etc.
-
Classification: According to the content and form of nickel, the waste is classified for subsequent treatment.
Chemical extraction
-
Acid leaching: Soak nickel-containing waste in sulfuric acid or hydrochloric acid to dissolve nickel to form nickel sulfate or nickel chloride solution.
-
Pyrometallurgy: For waste with high nickel content, nickel and other metals can be separated by high-temperature smelting.
Refining and purification
-
Electrolytic refining: The extracted crude nickel is further purified by electrolysis to obtain high-purity nickel.
-
Chemical precipitation: Impurity ions in the solution are removed by adding specific reagents.
Reuse
-
Product manufacturing: The recycled nickel is used to make stainless steel, batteries, alloys, electroplating materials, etc.
-
Circular economy: Recycling nickel not only saves resources, but also reduces environmental pollution, which is in line with the concept of sustainable development.
Nickel scrap has a high recycling rate. With the advancement of technology, the recycling process is constantly optimized, and energy consumption and costs are gradually reduced, which further promotes the development of the nickel recycling industry.
