Operations, Maintenance & Shutdown Services

Contract operations and maintenance is the new paradigm for mineral processing throughout the world as companies look for innovative ways in which to reduce the operating and maintenance costs while enhancing productivity. DRA Global is a leader in contract operations and plant maintenance, adding value to mining operations across the globe with its unique approach to meeting the individual needs of its clients. From coal, chromite, and ferrous metals to diamonds, gold, and platinum, DRA Global offers a wide range of services designed to make your (out) mineral processing requirements more cost effective while maintaining product quality, plant integrity and worker safety.


From electrical and mechanical component overhauls, for surface and underground equipment, through to mine and port construction projects, the organisation offers comprehensive services that encompass the entire project lifecycle from construction, through maintenance and optimisation to final decommissioning and deconstruction.


Seamless operations management requires effective plant design, intelligent engineering and efficient workflow processes. Over the past three decades DRA Global has operated and maintained 46 processing plants and commissioned 62 processing plants.

While DRA Global is acknowledged as leaders in coal, platinum and diamond contract operations, clients increasingly rely on their broader skill-set in a wide range of commodities, across all engineering disciplines and from concept to commissioning.


Regardless of the size or scope of these operations, DRA Global meets the financial and quality goals of contracts while clients gain continuity in production, even in exceptional conditions.

Through a tailored approach, solutions are developed to suit specific needs in specialised engineering services, maintenance, small engineering projects, condition monitoring and mobile field services.


DRA Global specialises in the operation and maintenance of refined coal facilities installed at power utilities in the United States of America. With an impressive history dating back to the late 1990s, through the design and construction of waste coal recovery plants, the organisation soon began designing, constructing, relocating and operating several synthetic coal facilities.

Now, with more than 25 years of industry experience, DRA Global has designed and constructed 19 refined coal facilities. Together with clients and technology partners, DRA Global has designed, tested and implemented processing technologies, which separate impurities and waste from raw coal and convert this coal into a quality-controlled fuel source.


These solutions reduce harmful emissions and improve the coal’s heading value, not only meeting the stringent requirements of the United States government but also reducing environmental impact.

These complete solutions in materials handling optimise processes within a power plant, from system design to commissioning and ongoing operations. DRA Global’s record is unmatched in building and operating materials handling systems for coal, limestone, petroleum coke, gypsum and ash through the application of cost-effective methodology. The organisation is able to consistently and efficiently meet the most challenging materials handling needs.


DRA Global developed MOMS (Mine Operations Management System) to provide mining and mineral processing companies with comprehensive operational intelligence.

MOMS is used to maintain better control over the supply chain, improve control and management of process plants and ensure assets are delivering maximum efficiencies. MOMS benefits core business outcomes, including increased productivity and improved return on investment through state-of-the-art technology.

The system produces and delivers accurate data to the right people at the right time, providing the required insight for pro-active decision-making. It enables clients to increase ore throughput while maintaining quality through a powerful combination of financial, distribution, costing, scheduling, maintenance and production tools.

The system is designed to provide an optimal experience to the end-user. MOMS facilitates the effortless management of workflow-driven processes such as procurement, production, budgeting, maintenance and internal cost requisitions.

By creating the reporting and input dimensions and frequencies, MOMS develops accurate costing, at a detailed process level and provides a comprehensive transactional analysis to clients.
