Evonik provides advanced solutions for filtration in mineral processing, helping mining operations improve solid-liquid separation and support process-water management.
Filtration is a critical step after mineral extraction, removing water from slurry to produce a dry concentrate for further refining or sale. It can support tailings dewatering, process-water recovery, and operational efficiency, depending on the filtration system and operating conditions.
Evonik offers a range of chemistries to enhance filtration performance.
TMT 15® is a ready-to-use reagent designed to support the removal of selected heavy metals from wastewater. Treatment performance depends on the metals present, water composition, dosage, process conditions, and applicable discharge requirements.
HYPROX® 600 is a hydrogen peroxide grade for applications such as ore leaching, concentrate preparation, and effluent treatment. Our water treatment additives help clarify process water, essential for effective vacuum and pressure filtration.
Foam control agents, such as AROSURF® and TEGO® Antifoams, prevent foam formation during filtration and slurry handling, improving throughput and reducing downtime.
Additionally, Evonik’s flotation reagents, including Arosurf® MG, indirectly support filtration by producing cleaner concentrates with lower moisture content, reducing the load on downstream filters.
