DRY COAL VALORISATION PLATFORM (DCVP)
ARIA’s Dry Coal Valorisation Platform (DCVP) transforms low-grade coal into higher-value products through advanced dry processing, beneficiation, mineral recovery, and energy conversion technologies. Unlike conventional coal processing methods, the platform maximises resource utilisation without relying on water-intensive operations. As a result, coal producers, power generators, and steel manufacturers can improve coal quality, recover valuable minerals, and increase the value of domestic coal resources. Furthermore, the platform helps reduce waste, lower operating costs, and support a more sustainable and profitable coal industry. By unlocking the full potential of high-ash coal, ARIA’s Dry Coal Valorisation Platform creates new opportunities across the energy, steel, and industrial sectors.

SUPER FINE ASH LIBERATION AT SUB 50 MICRONS
ARIA’s Vortex Aeroacoustics Technology uses high-velocity vortex airflow and acoustic energy to separate ultra-fine ash from coal without conventional grinding. The process creates controlled particle-to-particle collisions that release mineral impurities while preserving the natural structure of the coal. As a result, coal quality is improved without the high energy consumption associated with traditional milling systems.
This ash liberation process is particularly important for high-ash Indian coal, which often contains finely locked mineral matter. By removing ultra-fine ash particles, the technology improves dry coal beneficiation efficiency and enhances the quality of clean coal products. Furthermore, it supports higher energy efficiency, improved resource recovery, and better feedstock preparation for coal gasification and downstream chemical production. Consequently, ARIA’s Vortex Aeroacoustics Technology helps maximise the value of domestic coal resources while supporting sustainable coal processing.
SUPER FINE FLUIDIZED BED BENEFICIATION
Density-based dry separation using air fluidisation and vibration to stratify superfine coal into distinct mineral layers without water.
The ARIA Superfine Dry Fluidised Bed Beneficiation Process separates coal and mineral particles based on their density. In this process, superfine liberated coal powder enters a vibrating rectangular tank where compressed air fluidises the material from below. As a result, the combined action of airflow and vibration creates distinct layers of carbon, alumina, silica, and heavier mineral impurities.
The material then moves along an inclined discharge ramp for precise separation. At this stage, adjustable skimming plates collect each layer into separate product streams for further processing. Consequently, valuable carbon-rich material can be recovered efficiently, while mineral impurities are separated for mineral recovery and industrial use. Furthermore, the process improves dry coal beneficiation performance, enhances resource recovery, and supports the production of higher-quality clean coal products.
PLASMA GASIFICATION OF SUPER FINE COAL
In the ARIA Plasma Gasification Process, superfine beneficiated coal containing less than 7% ash is combined with steam and injected into a sealed reactor operating under negative pressure. Inside the reactor, plasma temperatures exceeding 2,000°C create an ultra-high-energy environment that converts the coal into a hydrogen-rich synthesis gas (syngas) within seconds. As a result, the process achieves rapid and efficient conversion of carbon into a valuable energy and chemical feedstock.
The extreme temperatures cause steam molecules to dissociate and react with carbon, producing syngas primarily composed of hydrogen and carbon monoxide. Furthermore, the high-temperature environment ensures near-complete carbon conversion while significantly reducing the formation of tars, char, and other unwanted by-products commonly associated with conventional gasification technologies.
At the same time, the inorganic mineral content within the coal melts and separates from the gas stream. These minerals flow to the bottom of the reactor as molten material and subsequently solidify into a vitrified, environmentally stable slag. Consequently, the process minimises waste generation while enabling the recovery and utilisation of valuable mineral fractions. The result is a clean and efficient coal-to-syngas process that supports power generation, hydrogen production, synthetic fuels, and downstream chemical manufacturing within ARIA’s Dry Coal Valorisation Platform.
WASTE TO VALUE FROM COAL REJECTS
The ARIA Dry Coal Beneficiation Process separates valuable mineral fractions from superfine coal through advanced density-based stratification. As a result, industrial minerals such as silica, alumina, and iron-bearing compounds can be recovered with typical purities of 85–90%. This process improves resource recovery while creating additional value from coal-derived mineral streams.
Furthermore, these recovered minerals can be supplied directly to industrial raw material markets or further upgraded through refining and thermal processing. Consequently, higher-purity mineral products can be produced for use in the cement, steel, metallurgy, ceramics, glass, and chemical industries. By recovering valuable minerals from coal, ARIA’s technology supports coal valorisation, waste reduction, and the development of a more sustainable and profitable coal industry.
