Gold anode plate casting machine
Gold anode plate casting machine is a specialized precious metal processing device, mainly used to convert raw materials such as molten gold, crude gold (Au≥85%) and gold-silver alloys (Ag≤30%) into standardized, high-quality gold anode plates. These anode plates are the core raw material for downstream gold electrorefining (the key process to produce 99.99%+ refined gold), and are widely applied in gold refineries, precious metal recycling plants (e.g., e-waste, jewelry scrap processing) and mining facilities-turning gold-rich raw materials into "ready-to-refine" intermediate products to ensure efficient and stable gold electrolysis.
Key Processes
The processing of gold anode plates by this equipment follows a scientific and orderly workflow, covering raw material treatment to finished product forming. The key steps are:
Raw material pre-treatment: Remove impurities (e.g., iron filings, oxide layers) from crude gold or gold-silver alloys to avoid affecting the purity of gold anode plates 2,Molten heating: Heat the pre-treated raw materials to 1250-1400℃ using an intermediate frequency furnace to melt them into molten gold
3,Quantitative casting: Use a servo-driven casting module to pour molten gold into molds in a fixed amount, ensuring uniform weight of each anode plate
4,Cooling and setting: Accelerate the solidification of molten gold in molds through a cooling system, with a solidification time of 30-60s
5,Demolding and transfer: Demold the solidified gold anode plates and transport them to the acid washing station via a transfer trolley
6,Quality inspection: Check the size, weight and surface flatness of gold anode plates to ensure they meet electrorefining requirements
