OUR BUSINESSES

PROCESSING & REFINING

Chimie Circuit specializes in the processing, refining, and recovery of all liquid and solid materials containing precious metals (gold, silver, palladium, rhodium)—such as industrial waste, manufacturing by-products, and waste electrical and electronic equipment (WEEE).

 

EFFICIENCY & RELIABILITY

With state-of-the-art industrial facilities, we aim for operational and environmental excellence. Our site is classified as an ICPE facility and holds ISO 9001 (quality), ISO 14001 (environment), and ISO 45001 (occupational health and safety) certifications.

SERVICES & PRODUCTS

LOGISTICS

As an industrial waste processing company, we understand the importance of waste logistics.

We handle all waste streams from the industrial sector and from WEEE (Waste Electrical and Electronic Equipment) processing activities, managing the treatment and refining of materials to extract non-ferrous and precious metals. Whether the waste is liquid, semi-solid, or solid—and whether hazardous or non-hazardous—we hold the necessary permits for its transport and processing.

Our waste transport management complies with legal requirements and helps optimize the economics of recycling. We also provide containers to our industrial clients to facilitate the collection and storage of their materials.

MECHANICAL TREATMENT

Mechanical processing is a method of preparing and homogenizing incoming materials by adjusting their particle size. Grinding enables the material to be sorted using electromagnetic, density-based, and optical processes.

HYDROMETALLURGICAL TREATMENT

Hydrometallurgical processing is a method of metal production involving solvation (dissolution) in an acidic, basic, or organic medium, leading to the production of pure metals via selective or non-selective electrolysis.

PYROMETHALLURGICAL TREATMENT

Pyrometallurgical processing is a method of producing metals from recycled materials through pyrolysis, melting, and refining.

ANALYZES

The smelting output undergoes rigorous monitoring, particularly regarding the material quantities being processed (weights before and after smelting). Sampling—whether for liquid or solid materials—is carried out in accordance with industry best practices, and all analyses are performed by our laboratories (both internal and external), ensuring clear and transparent information.

It is this high level of service quality that enables us to maintain trusting relationships with our clients and positions us as a leader in this field today.

REFINED METALS

Our business involves extracting and separating precious metals. We handle a diverse range of materials, which vary significantly in terms of metal concentration—ranging from low to medium or high. Materials with low or medium precious metal concentrations undergo a specific pre-treatment process to concentrate the metals, using either solvation or pyrolysis. The solvation method, in particular, enables the separation of precious metals from copper. Once separated and concentrated, the metals are homogenized and cast into ingots before being sent to the specific refining processes for each metal.

COMPLETE SERVICE

From small and medium-sized enterprises (SMEs) to industrial sites, we offer our clients a complete technical solution adapted to all types of waste and certified (ISO 9 001 : 2015 ; ISO 14 001 : 2015 ; ISO 45001 : 2018).

Our service includes:
– Sorting, collection, and transport
– Material processing
– Recovery
– Metal provision
– Supply of precious metals in physical and derivative forms
– Service monitoring
– Traceability of processing and recovery, and reporting

All our tests and analyses are carried out by laboratories and testers accredited by COFRAC and NADCAP and approved by the Banque de France.
