Cutting-edge chemical refining maximizes your return.
Cutting-edge chemical refining processes maximize the return on your precious metals. Our competitors predominantly focus on melting and sweeps preparation - often low grade / high volume - with little chemical solution capabilities. At ACC, we dedicate over 50% of our operations to chemical refining, making us one of the largest chemical refiners in North America.
Cyanide Chemical Gold Stripping
- Ideal for material that is plated with a single layer of gold
- When utilized properly, recovers 100% of gold.
- Rotary barrels can strip from small lots up to 10,000 pounds/day
- Material is stripped, rinsed & inspected to ensure all gold has been removed
- Remaining solution is weighed in a way that suits your specific preference
- Partners are also paid based on the base metal content
- All gold assays include gold dragged into a double rinse station, providing zero loss of gold
Cyanide Based Solutions
- ACC can process metal from solution-refining up to .9995%-.9999% pure grain
- That level of purity makes us one of the few refiners in the industry that qualifies as a Primary Refiner
- After we blend material into a homogeneous mixture, we use one of the most accurate sampling techniques in the industry to properly assay partners’ material
- Proprietary techniques honed over decades of experience are used to extract the precious metal content from material
Acid Digestion
- Acid digestion is ideal for material that has multiple plated layers
- Acid digestion is also ideal for removing genuine gemstones from jewelry without harm
- Material is completely dissolved into liquid form in our unique acid digestion kettles, the only ones of their kind in the entire USA
- We separate and precipitate out the precious metals from the non-precious metals for maximum precious metal recovery
Acid Based Solutions
- We specialize in acid waste streams
- Our acid solutions services are a major reason why we process the most plating solutions in North America
