Services & Materials

What We Buy and Recycle

We offer competitive pricing for a wide range of materials containing precious metals. We provide free collection and secure logistics with precise material evaluation.

Automotive Catalysts

We purchase and recycle all types of end-of-life catalytic converters (ceramic and metallic honeycomb). Payment is based on the actual content of Pt, Pd, and Rh after assay.

Industrial Catalysts

We manage the recycling of spent catalysts from the chemical, petrochemical, and pharmaceutical industries. Each type receives a custom quote.

E-Scrap & IC Chips

We accept and process a variety of electronic scrap including integrated circuits (ICs), computer processors (CPUs), telecommunications boards, and other high-grade scrap for the recovery of Gold, Silver, and Palladium.

Global Logistics

We offer free, secure, and insured collection services for materials worldwide, regardless of volume. We handle all necessary documentation.

Evaluation & Assaying

Your materials undergo precise analysis in our laboratory using modern methods (e.g., ICP-OES) to determine exact metal content. You receive a detailed certificate of analysis.

Our Process

Our Transparent and Advanced Refining Process

Our multi-stage, environmentally sound process is designed for maximum efficiency and recovery.

Collection & Sorting

Materials are securely received, weighed, and meticulously sorted.

Preparation & Sampling

Materials are processed (crushed/milled) and a representative sample is taken for analysis under strict chain-of-custody protocols.

Hydrometallurgical Refining/Smelting

The material undergoes chemical treatment or smelting to dissolve and separate the base metals from the precious metals.

Purification & Precipitation

Advanced techniques are used to isolate and purify individual precious metals.

Melting & Settlement

Pure metals are cast into bars or ingots. You receive a final settlement report and payment based on the precise results.
