Meiteng’s full-size coal dry separation plant in Mongolia: design notes for mine engineers
Reviewed by Joe Ashwell

First reported on International Mining – News
30 Second Briefing
Meiteng Technology’s full-size intelligent coal dry separation plant in Mongolia has run stably since October 2025, using its proprietary DCP Full-Size Coal Dry Separation Dream Plant system under harsh continental climate conditions. The installation applies fully dry, sensor-based coal separation without process water, reducing reliance on traditional dense medium circuits and associated tailings dams. For mine operators in arid or freezing regions, the project signals growing viability of large-scale dry beneficiation where water supply, freezing pipelines and slurry management constrain conventional plants.
Technical Brief
- The installation is described as “intelligent”, implying integrated sensor control, automated sorting logic and centralised plant optimisation.
- Dry separation eliminates slurry handling equipment, enabling a simplified plant layout and reduced rotating machinery inventory.
- Absence of process water circuits removes risk of pipeline freezing, pump cavitation and thickener rake torque overloads in sub‑zero conditions.
Our Take
Meiteng Technology’s coal work in Mongolia sits alongside its XRT ore sorting deployments for lead-zinc in Tajikistan (commissioned in 2026), signalling a push to commercialise intelligent dry or pre-concentration separation across multiple bulk and base-metal commodities.
Stable operation reported from 2025 positions this DCP Full-Size Coal Dry Separation Dream Plant as an early reference site; for other coal projects tagged under ‘Projects’ and ‘Sustainability’, such a reference can materially de‑risk adoption of dry separation in arid or water‑constrained regions.
