FLOMIN™ GDA are high-performance processing aid that control clays and fine particles behavior, improving grinding efficiency and washing/separation performance while reducing slurry viscosity, energy and water consumption, and metal losses to tailings.
FLOMIN™ GDA products can be used in different mining operations and especially in grinding, washing & desliming, magnetic separation and flotation.
The FLOMIN GDA range is designed for various applications in order to help improve global plant performance:
Grinding is one of the most energy-intensive stages in mineral processing. By reducing slurry viscosity and eliminating the cushioning effect of dense pulps, FLOMIN™ GDA directs more mechanical energy toward particle breakage. This allows AG, SAG, rod, ball and stirred mills to run at higher solids without choking, while lowering energy consumption by up to 10% in conventional circuits and 30% in ultrafine grinding. Improved rheology also enhances hydrocyclone efficiency, reduces circulating loads, limits wear on liners and media, and prevents fines agglomeration for a sharper PSD that boosts downstream flotation and filtration.
Washing & Desliming Fine clays and ultra-fines often coat valuable minerals and increase slurry viscosity, reducing washing efficiency. FLOMIN™ GDA slough-off clay aggregates and removes slime coatings, maintaining effective separation even with high-clay ores. This improves downstream recovery and keeps equipment operating at higher throughput with less screen blinding and fewer cleaning shutdowns.
Flotation Clay-rich pulps hinder flotation by thickening the slurry and masking mineral surfaces. FLOMIN™ GDA cleans these surfaces and reduces viscosity, improving interactions with collectors, promoters, and modifiers. The result is higher concentrate grade and recovery, faster flotation kinetics, and the ability to operate at higher solids content, significantly increasing throughput and metal production in clay-rich ores.
Magnetic Separation Fine magnetic particles naturally form magnetic flocs that trap gangue minerals such as clays and silicates, lowering concentrate grade and causing iron losses. FLOMIN™ GDA breaks down these flocs, keeps particles apart, and prevents obstruction between magnetic poles. This ensures cleaner separation, higher iron recovery, and more stable magnetic performance without modifying equipment.
FLOMIN™ GDA is used as a grinding aid to improve mill throughput and reduce viscosity-related constraints, as a washing and desliming aid to enhance clay removal , and as a processing aid in flotation and magnetic separation circuits where clay coatings and fines interfere with selectivity.
By improving pulp conditioning upstream, FLOMIN™ GDA stabilizes downstream separation steps, enabling more efficient recovery, reduced reagent stress, and improved overall plant performance.
