Reimagining XRT Technology: Dry Sorting with Maximum Precision

The mining industry is under pressure: rising energy prices, scarce water resources, and tightening environmental regulations demand new solutions.

Traditional wet processing methods are resource-intensive and lead to high operating costs.

With the allsort® XRT Sorter, allmineral presents a sustainable alternative — a high-end system for the dry processing of ores, coal, and recycling materials.

The key innovation: through sensor-based X-ray transmission (XRT), materials are sorted completely dry, without the use of water or chemicals — while maintaining consistent sorting quality.

Technological Core: allsort® XRT Sorter

The allsort® XRT Sorter uses X-ray transmission (XRT) to distinguish materials based on density. Even heavily soiled surfaces are no issue — the technology “looks” inside each particle.

This enables valuable raw materials to be separated cleanly and precisely from waste rock.

  • Grain size: 10–120 mm
  • Throughput: 75–150 t/h
  • Compact design with dust- and water-tight construction

Sustainability and Efficiency

  • No water consumption, no chemicals
  • No wastewater or sludge treatment required
  • High energy efficiency
  • Small footprint – high capacity at small footprint

The result: significantly lower CO₂ emissions and minimized environmental impact — without compromising performance.

Economic Advantages

Dry processing eliminates the need for costly sludge handling, reducing operating expenses.

Thanks to sensor-based precision, resource utilization is improved, and the integrated system software continuously monitors process data to maximize efficiency.

Greater profitability with lower energy consumption — that’s sustainable mining in practice.

Applications and Flexibility

  • Ores
  • Coal
  • Recycling materials

The system can be seamlessly integrated into existing operations and is built with German engineering — durable, robust, and easy to maintain.

Reduced Environmental Impact Through the Elimination of Water and Chemicals

This guarantees operational reliability, high availability, and long-term efficiency.

A key advantage of sensor-based dry sorting lies in its dramatically reduced environmental impact. 

The allsort® technology operates entirely without water, eliminating both wastewater and sludge management. Chemical additives such as flotation agents or heavy media are also unnecessary — sorting is performed purely physically via precision X-ray sensors.

This dry processing method is dust-free, energy-efficient, and space-saving. It requires neither water treatment nor large basins, significantly reducing the ecological footprint of the entire process. By eliminating water- and energy-intensive process steps, CO₂ emissions are measurably reduced — a clear contribution to more sustainable raw material extraction.

Especially in arid regions or areas with strict environmental regulations, this technology is a decisive factor for the economic viability of modern mining projects. Eliminating tailings ponds and sludge basins also means less land disturbance and fewer long-term environmental risks.

High-tech sorters like allsort® conserve natural resources and represent mining that convinces both ecologically and economically.

Conclusion – A Future-Oriented Standard in Mineral Processing

With the allsort® XRT Sorter, allmineral demonstrates that ecology and profitability are not mutually exclusive.

Dry processing is becoming the new benchmark for efficiency and sustainability in mining — a technology that conserves resources while boosting profitability.
