The industrial gold electrolysis process—primarily known as the Wolver process—is an electrochemical refining system that refines crude gold anode rods (typically 90% to 98% pure) into ultra-pure fine gold crystals at the cathode, achieving a purity of 99.99% (4N) or 99.999% (5N).

The gold electrolysis process flow, industrially known as the Wohlwill process, involves using crude gold (alloy gold ingots) with a purity of 90%–99% as the anode. Through an electrochemical reaction in a specific acidic electrolyte, high-purity gold (up to 99.99% (4N) or even 99.999% (5N)) is deposited on the cathode.

Metal smelting furnace equipment is a core thermal equipment in metallurgical, casting, machinery manufacturing, and precious metal refining workshops.

Silver-palladium alloys are widely used in multilayer ceramic capacitors (MLCCs), dental alloys, electronic contacts, and catalysts.

An automated casting system is a core component of a modern intelligent foundry.

A gold hydrometallurgical workshop is an industrial production facility that uses chemical solutions (such as cyanide, thiosulfate, or chloride) to leach, concentrate, and recover gold from ores, concentrates, or e-waste.

Silver electrolysis equipment consists of specialized hardware configurations designed to manage electrical currents, chemical reactions, and physical metal recovery.

A vacuum casting machine utilizes a negative pressure environment to draw liquid materials into a mold, effectively eliminating trapped air bubbles to create highly dense, flawless, and finely detailed objects.

Silver electrolysis is an electrochemical process used to purify silver to ultra-high levels (up to 99.99%) or to coat objects with a layer of silver. It works by passing a direct electric current through an electrolyte solution, causing silver ions to migrate from an anode (positive electrode) and deposit onto a cathode (negative electrode).
