How does Precious metal refining equipment for extracting gold and silver from electronic waste work?

Our refining systems utilize advanced hydrometallurgical and electrochemical processes to extract gold and silver from e-waste:

Crushing & Sorting: E-waste is shredded and separated to isolate metal-rich components.

Leaching & Dissolution: Precious metals are dissolved using non-toxic or low-toxicity solvents (alternative to cyanide-based methods).

Electrowinning & Precipitation: Gold and silver are recovered via electrolysis or chemical reduction.

Purification & Smelting: Final refining ensures 99.9% pure gold and silver.

What is the process flow of Precious metal refining equipment for extracting gold and silver from electronic waste?

The process flow of Precious metal refining equipment for extracting gold and silver from electronic waste includes the steps of "pretreatment-fire smelting-electrolytic refining-wet leaching-reduction precipitation-refining and purification", as follows:

Pretreatment: Electronic waste is disassembled, crushed, and sorted to remove non-metallic impurities such as plastics and ceramics to obtain raw materials containing precious metals.

Fire smelting: The raw materials are mixed and smelted with flux (such as borax and sodium carbonate) in a high-temperature furnace, and the precious metals are enriched in copper or lead alloys to form "precious lead".

Electrolytic refining: Precious lead is used as an anode for electrolysis, copper and other base metals are dissolved, and gold and silver are deposited in the anode mud.

Wet leaching: The anode mud is dissolved by aqua regia or cyanide, and a solution containing gold and silver is obtained after filtration.

Reduction precipitation: Add a reducing agent (such as sodium sulfite, oxalic acid) to precipitate crude gold and silver.

Refining and purification: Crude gold is purified to 99.99% by electrolysis or chlorination; crude silver is electrolyzed or chemically reduced to obtain high-purity silver.
