When Rio Tinto considered options to increase the current capacity of the HD1 South Plant to meet the future needs of their operation, EMtek prospered at the opportunity to innovate. The current system at the HD1 South Plant was operating below setpoint due to numerous bottleneck constraints. EMtek was engaged to address the current capacity constraints to improve the performance of overland conveyor in combination with improvements to the control system and modification of the transfer chutes. The successful result enabled Rio Tinto to increase throughput to the future planning requirements.
