DMT GmbH & Co. KG

Essen, Germany

Expertise

 

DMT is an industrial and lead partner of the Re-Activate project. As a leader and driver in the exploration, mining services and technology sector, DMT is constantly developing innovative and robust solutions for this sector. Re-Activation of former mine sites is focused on extraction of mainly critical raw materials from mine tailings and dumps in a sustainable manner. This requires development and optimization of technologies and methods for assessment of secondary mineral resources and hydrometallurgical heap, in-situ and tank leaching.

 

DMT core activities focus on sensor-supported monitoring of mining operations, automation of exploration, mining and extraction processes, reactivation and/or remediation of abandoned mine sites, and assessment and certification of mineral resources and ore reserves. DMT owes its expertise to a history of long-term experience in the mining sector.

 

Exploration & mineral resource estimation of mine tailings

 

The exploration service at DMT encompasses prospecting, exploration and evaluation of different mineral deposits, especially, underground monitoring and investigations. Identification and monitoring activities via geological modelling, geophysics, surveying and geo-information and geo-technologies like 3D scanning tools, core scanners, etc.

 

Mining engineering of mine planning and closure

 

DMT offers services from technical feasibility studies, mine planning to closure and restoration including mine layout and extraction planning, rock mechanics (detailed planning of all mine workings), mine ventilation, gas management, gas drainage and mine gas utilization, mineral processing, mine closure and abandoned mining.
