Design, engineering and construction of mineral-processing facilities

Close cooperation between Minopex and its sister company, DRA Mineral Projects, offers clients a single source for all for their processing requirements. We ensure that execution of a project, from inception through feasibility studies, design, detailed engineering and construction to O&M, is a seamless transition.

O&M for platinum-concentrator, coal-processing and diamond-processing facilities

Minopex operates and maintains 15 mineral-processing facilities in Southern Africa. Of these, ten are platinum-concentrator facilities, four are coal-processing facilities and one is a diamond-processing plant.

Besides our long-term contract operations, we are jointly involved in a number of short-term projects offering commissioning and technical assistance to new clients.

O&M for new and existing mineral-processing facilities

By handing over certain aspects of the processing function to Minopex, new mines can reduce upfront capital costs for operational equipment and site facilities, while operating mines can minimise operating costs.

We guarantee continuity of production, have the flexibility to manage exceptional conditions and are able to remain focused on the specifics of the operation under our control, ensuring we achieve the financial and quality goals of the contract.

ISO-certified provider of O&M services for mineral-processing

All Minopex operations are run to exacting quality standards and the company boasts an ISO 9001:2000 multi-site certification, where present and future Southern African operations managed by Minopex are ISO 9001:2000 certified.

The company’s operations are networked to each other and the head-office databases using a wide area network (WAN), and are supported by the national data and voice communication network backbone.
