High-purity zinc powder used in precious metal refining, silver recovery, gold recovery, and metal precipitation applications. Zinc plays a critical role in several refining processes by helping recover dissolved precious metals from solution.
Commonly used in the Merrill-Crowe process, zinc powder is added to cyanide solutions containing dissolved gold and silver, causing the precious metals to cement out of solution for recovery. Zinc is also used in the Parkes Process for separating silver from molten lead.
Ideal for refiners, metal recovery operations, laboratories, educational applications, and advanced hobby refining.

HOW ZINC IS USED IN REFINING
Merrill-Crowe Process:
• Zinc powder is added to clarified cyanide solution
• Zinc displaces dissolved gold and silver
• Precious metals precipitate from solution
• Metals are filtered, collected, and refined further
Parkes Process:
• Zinc is added to molten lead containing silver
• Silver bonds with zinc
• Silver-rich zinc layer is separated for recovery
