1LB Zinc Powder Gold Silver Recovery Refining Metal Precipitant Dust Casting Description
GTE 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.
