Solid-Liquid Separation Systems
Our heavy-duty hardware systems are custom-engineered to manage aggressive slurry profiles and high-tonnage mining outputs across global processing operations. By optimizing rake torque mechanics, feedwell hydrodynamics, and underline discharge densities, our High-Rate, High-Density, and Paste Thickeners consistently deliver maximum water recovery loops while minimizing chemical flocculant consumption. Paired with high-efficiency automatic Filter Presses, we provide turnkey dewatering solutions designed for optimal plant lifecycle reliability.
NanoBubble Design & Filtration
Nanobubbles provide superior performance in gold leach circuits, particularly in heap leaching and cyanidation processes, where oxygen plays a critical role in dissolving gold from ore. Adopting nanobubble technology in your gold leach circuit means faster processing, higher gold recovery, and sustainable operations. The Nanoleach Pro sparging system has proven to be highly effective in producing the optimally sized bubbles required for maximising oxygen mass transfer rates. With both standard systems and customizable solutions available, our technology delivers unmatched benefits in every application. Engineered for seamless integration and straightforward installation, we accommodate versatile flow rates, volumes and gas types.
Water & Wastewater Infrastructure
Quest provides modular, plug-and-play water and wastewater treatment plants. By pre-fabricating unit operations—such as advanced screening, lamella clarifiers, and Dissolved/Suspended Air Flotation (DAF/SAF) systems—into compact, factory-tested skids or containerized units, operators achieve rapid deployment, strict quality control, and unparalleled footprint efficiency. This synthesized approach eliminates on-site interface risks, slashes project timelines by up to 50%, and provides industries with a flexible, future-proof asset capable of scaling seamlessly alongside shifting demand. Turnkey solutions combine in-house expertise with specialist suppliers.
