Learn More →Switzerland occupies a singular, highly authoritative position in the global gold economy. Despite having minimal active primary gold mining within its alpine borders, the country is home to several of the world’s largest and most technologically advanced gold refineries, including Valcambi, PAMP, Argor-Heraeus, and Metalor. These facilities collectively process an estimated 50% to 70% of the world’s annual gold output. As a direct consequence, the technological, ethical, and environmental standards established by the Swiss federal authorities and industry watchdogs act as de facto global regulations for mineral exporters worldwide.
Any mining operation looking to secure supply contracts with Swiss refiners must demonstrate strict adherence to the OECD Due Diligence Guidance for Responsible Supply Chains. This framework demands verifiable compliance regarding mineral origin, the complete elimination of hazardous chemicals such as mercury from primary concentration processes, and a minimal greenhouse gas footprint. As a result, modern mining enterprises are transitioning away from chemical leaching methods at raw extraction sites in favor of physical gravity concentration and advanced mechanical comminution circuits.
Our processing plants and comminution units are designed specifically to assist operators in meeting these requirements. By utilizing high-efficiency jaw crushers, precision ball mills, and chemical-free gravity separation devices, we ensure that the recovered gold concentrate is of the highest physical purity, ready for safe transit and direct smelting under Swiss-compliant sourcing agreements.
Our machinery configurations support completely mercury-free processing flowsheet designs, ensuring your operations remain compliant with the London Bullion Market Association (LBMA) standards and the Swiss Better Gold Association (SBGA) sourcing criteria.
Integrating optimized wet pan mills and ball mills maximizes mineral liberation at coarser fractions, reducing unnecessary energy expenditure during downstream concentration phases and lowering localized operating costs.
Built with high-manganese steel castings and robust structural bases, our plants are resilient against extreme environmental variations, from high-altitude Swiss laboratories to heavy tropical mining sites.
Achieving high recovery rates while honoring the ecological sensitivities of alpine and regional zones in Switzerland requires a deep understanding of localized mining and reclamation constraints. Switzerland's environmental protocols demand zero chemical discharge, minimal dust production, noise containment, and immediate soil reclamation.
Consequently, local exploration, academic research, and commercial recycling plants operate under entirely different paradigms than standard bulk mining operations. Our solutions address this by dividing the technical workflow into three highly targeted functional suites:
For Swiss research institutes, geological departments, and refinery labs, we supply scaled-down, highly controllable jaw crushers and ball mills. These machines allow precise testing of mineral samples without contaminating the workplace or creating excess dust emissions.
For historic or artisanal alluvial extraction in the Swiss Alps, mobile, self-contained washing plants and sluice boxes are critical. These systems operate with recirculating water pumps, eliminating the discharge of muddy waste into local rivers and streams.
Modern Swiss urban mining relies on reprocessing electronic scrap and industrial waste. Our fine grinding mills and high-efficiency crushers reduce circuit boards and catalysts into fine powder, allowing refiners to extract high-purity precious metals.

Key R&D pathways currently active within our design divisions include:
By implementing real-time wear sensors and motor load analytics on our Ball Mills, we optimize the feed rate dynamically. This prevents over-grinding, reduces energy consumption by up to 15%, and ensures the output conforms precisely to the required gravity circuit parameters.
Recognizing the absolute premium placed on clean water sources in regions like Switzerland, our modern processing plant configurations utilize advanced clarifiers and compact plate filters. This enables the recycling of over 95% of process water within the gravity loop.
We are expanding the development of our diesel-electric hybrid engines for primary crushing units. This allows exploration companies to run highly efficient diesel units in remote locations or switch seamlessly to grid electrical power in areas with strict emissions caps.
Impact crusher is a kind of secondary crushing equipment which uses impact power to crush materials. Impact crusher is characterized by easy maintenance, high reduction ratios and high efficiency to produce precisely cubic shape products. It is designed with three crushing chambers, seamlessly connected rotor, wear-resistant blow bar and installation of insert type. Moreover, it has tooth type liner, gradient designed bearing seat, frame with several openings and screws or hydraulic start-up devices. Impact crushers can be used in all different stages of size reduction from primary crushing to the last step of the crushing process.

Get In TouchGet authoritative insights regarding mechanical processing setups, regulatory compliance, and best engineering practices for gold mining equipment intended for Swiss refinery sourcing.
Swiss refineries require strict documentation showing that the imported gold concentrates are sourced using environmentally sound, mercury-free, and cyanide-reduced methods. Consequently, operations seeking access to Swiss buyers must prioritize gravity separation equipment (such as shaking tables, gold centrifuges, and advanced sluices) coupled with high-efficiency physical grinding plants like ball mills and wet pan mills.
A high-precision laboratory jaw crusher is vital for initial core sample sizing and metallurgical testing. It reduces crude rock to a consistent particle size without external contamination, allowing mining labs and research institutes in Switzerland to run precise assay tests to verify the viability and chemical composition of the ore deposit.
Wet pan mills are continuous grinding systems that combine grinding and mixing functions, often used in small-scale operations due to lower initial capital expenditure and ease of maintenance. Ball mills, on the other hand, offer highly controlled particle liberation size, higher throughput capacities, and integrate cleanly into large, automated mineral processing circuits that require precise particle sizing.
If the ore is not crushed and ground to its optimal liberation size, the gold remains locked inside the host rock (like silica or sulfide matrices), resulting in poor gravity recovery. Over-grinding is also detrimental as it turns the gold into fine slimes that can bypass gravity concentration tables. Our engineered ball mills and impact crushers allow operators to target the precise liberation window.
Yes. Our plants support physical gravity separation without the use of chemical reagents. By eliminating mercury and cyanide from the extraction stage, our equipment produces clean, high-grade concentrates that align perfectly with the SBGA's focus on mercury-free gold recovery and sustainable sourcing.
Our mobile alluvial gold washing plants are highly modular and can scale from 10 tons per hour (tph) for exploration and small-scale operations up to 150+ tph for larger commercial alluvial projects. The portable configurations are designed for quick site setup and easy relocation across varied terrain.
We provide comprehensive technical documentation, compliance certificates, and structural engineering layouts.
