What is Gold and Silver Refining Equipment?
Gold and Silver Refining Equipment is used to purify gold mud, gold-containing heavy sand or waste materials to high-purity gold and silver and other precious metals to meet quality standards (gold ≥ 99.99%, silver ≥ 99.9%); it uses hydrometallurgy (chemical dissolution, electrolysis) or pyrometallurgy (high-temperature smelting, vacuum distillation) technology, and is equipped with waste gas and wastewater treatment systems to purify crude materials containing impurities (such as waste jewelry, industrial waste, etc.) to a purity of more than 99.9%.
Why Choose Our Gold and silver refining equipment?
Gold and silver refining equipment has high recovery rate and purity, low cost and short cycle for gold and silver refining. It is a fully customizable system with a processing capacity of 100kg/day under standard configuration. It is suitable for small refineries to industrial operations. Its core advantages include:
High recovery rate and purity: Using chemical method or smelting process, the gold recovery rate can reach 99.96% and silver can reach 99.9%; the product purity meets international standards (gold ≥ 99.99%, silver ≥ 99.9%), reducing the loss of precious metals.
Low cost and short cycle: The cost of gold refining operation is only 0.13 yuan/gram, and the production cycle is shortened to 36 hours (gold) and 20 hours (silver), increasing efficiency by 50%.
Fully automated and pollution-free: The PLC system controls the process parameters throughout the process to realize the mechanization of liquid transportation; negative pressure operation + gas purification technology ensures that waste gas and wastewater meet the discharge standards (silver content in sewage <0.5mg/L), and there is no process waste residue.
