GRAVICON applies gravity-based beneficiation to primary mineral resources and technogenic materials where separation by density is physically effective. The technology is used for coal, metallic and non-metallic ores, slags, tailings, and waste dumps, including materials previously considered uneconomic. Each material is assessed through laboratory testing and process modeling before industrial implementation.
GRAVICON structures its material expertise into four distinct groups based on origin, physical properties, and processing complexity.
This classification reflects the practical engineering approach used to select optimal beneficiation technologies — from primary mineral resources to complex multi-component industrial and technogenic materials.
GRAVICON technologies are used for beneficiation of primary mineral resources where gravity separation is effective by density contrast and particle size distribution. The solutions apply to metallic and non-metallic ores, as well as energy minerals, with plant configuration adapted to material properties and required product specifications. Materials include coal, iron, manganese, lead, tantalum–niobium, titanium and polymetallic ores, gold-bearing ores, diamonds, barite, garnet sands, and vermiculite.
A significant part of GRAVICON expertise lies in processing technogenic and secondary deposits formed by mining and metallurgical operations. These materials often combine valuable components with complex granulometry and contamination, requiring flexible and energy-efficient separation technologies. Materials include: Ferroalloy slags, metallurgical slags, lead-containing slags, industrial waste dumps, secondary mineral residues, slimes and fine fraction beneficiation
GRAVICON develops engineering solutions for complex multi-component industrial wastes, where conventional beneficiation methods are ineffective. Processes are designed to separate several valuable products within a single technological flow. Key application: Red mud recycling with separation into: - silica sand (SiO₂); - iron ore concentrate (IOC); - non-ferrous metals (vanadium, titanium); - rare earth elements (REEs).
Processing of coal waste dumps (terrikons) is one of GRAVICON’s core specializations. Our technologies allow recovery of usable coal fractions while reducing ash content and environmental impact, transforming legacy waste into an economically viable resource. This direction combines high industrial relevance, short payback periods, and strong environmental effect, making it especially attractive for large-scale redevelopment projects.
GRAVICON technologies support EU Taxonomy–aligned activities by enabling resource recovery from technogenic deposits and industrial waste with measurable environmental benefits. Processing of waste dumps, slags, red mud, and tailings reduces land occupation, limits long-term soil and groundwater contamination, and contributes to remediation of legacy mining sites.
All solutions are based on physical (gravity) separation, operate without chemical reagents, and use closed-loop water circuits with low specific energy consumption. By converting waste into marketable products or environmentally safe materials suitable for reuse or reclamation, GRAVICON technologies contribute to circular economy principles, combining environmental risk reduction with economically sustainable industrial operation.
