Learn moreThe Concentrator Plant is a critical part of the Oyu Tolgoi copper mining operation, linking raw ore extraction with downstream metal production. As mined ore contains a low percentage of copper, the concentrator performs essential physical and chemical processes—such as crushing, grinding, and flotation—to upgrade the ore into a higher-grade copper concentrate suitable for smelting and refining. Equipment reliability within the concentrator is fundamental to safe, efficient, and uninterrupted production. Khaanzaa Service’s reliability services focus on ensuring consistent plant availability through planned maintenance, timely response to unplanned breakdowns, and condition-based equipment diagnostics. Our reliability team, comprising both mechanical and electrical specialists, supports key process areas, including: Grinding and milling circuits Flotation, enrichment processes, and tailings storage facilities Concentrate packing and handling facilities Through disciplined maintenance practices and technical expertise, we contribute to stable plant performance, reduced downtime, and sustainable concentrator operations.
