Precious Metal Extraction
With advanced hydrometallurgical technology, we extract high-purity precious metals from industrial waste.
Technology That Finds Invisible Value
In various industrial wastes such as semiconductor process scrap, industrial catalysts, and plating wastewater, there are precious metals with value beyond our imagination. Core World gives new life to precious metals such as gold, silver, palladium, and platinum sleeping in waste through advanced hydrometallurgical technology and a precision analysis system.
Recycling Process
Raw Material Receiving & Analysis
Receive raw materials containing precious metals such as scrap, dust, and sludge from various industrial sites, and conduct precise component analysis.
Melting & Leaching
Go through a melting and leaching process that selectively dissolves the target metal using a solution suitable for the characteristics of the analyzed raw material.
Selective Separation & Refining
Separate only the target precious metals from the solution and increase the purity by removing impurities through several refining steps.
Final Productization
Produce and supply high-purity refined precious metals in final product forms that meet market demands, such as gold bars and silver bars.
