E-waste precious metal refining and extraction technology equipment

Currently, e-waste disposal is facing enormous challenges. A large amount of e-waste is improperly disposed of, resulting in waste of precious metal resources. Some precious metal extraction methods still use traditional smelting methods, which are not only time-consuming and energy-consuming, but also pollute the environment. Therefore, finding more effective and environmentally friendly extraction methods for precious metals has become an urgent need. As an experienced manufacturer of e-waste recycling equipment, SUNY GROUP has rich experience and technical equipment in e-waste recycling, especially precious metal refining and extraction.

Technical process:

Precious Metal Refining Process

Pre-processing: E-waste first undergoes physical sorting and shredding to remove non-metallic parts and finely break the e-waste into smaller particles.

Acid leaching extraction: soak the crushed e-waste particles in an acidic solution, and dissolve the precious metals to form metal ions through the dissolution of the acid.

Solution processing: Further processing of solutions containing noble metal ions, such as filtration, precipitation and neutralization steps, to remove impurities and purify noble metal ions.

Electrolytic refining: use electrolytic method to reduce noble metal ions to pure noble metal, and deposit on the electrode to form metal flakes or particles with high purity of noble metal.

Refining equipment:

Crushing equipment: Used to finely crush e-waste into smaller particles, such as crushers and pulverizers.

Acid leaching equipment: including acid leaching tanks and stirring equipment, used to immerse electronic waste particles in acidic solution to dissolve precious metals.

Solution treatment equipment: including filters, sedimentation tanks and neutralization equipment, used to treat solutions containing precious metal ions to remove impurities and purify precious metal ions.

Electrolysis equipment: includes electrolytic cells, electrodes, and power supplies for the reduction of precious metal ions to pure precious metals.

The refining and extraction of precious metals from e-waste is an important environmental protection task, which helps to reduce resource waste and environmental pollution. By adopting advanced technical processes and equipment, precious metal resources in electronic waste can be efficiently extracted and recycled. However, in order to achieve sustainable development, further research and promotion of more environmentally friendly and economical precious metal extraction methods, as well as enhanced public awareness to promote the proper disposal and recycling of e-waste, are required. Only through joint efforts can the maximum utilization of e-waste precious metal resources and environmental protection be realized.
