The Iron Ore Company of Canada (IOC) transports approximately 15 Mt/y of iron concentrate and pellets 414 km by rail from its Carol Lake mine in Labrador to its port on the St. Lawrence River.
To meet future expansion targets, investments in fleet and infrastructure will be required to increase the capacity of the system.
IOC commissioned Ausenco to create a simulation model of the system “from mine to port” in order determine the current capacity and to identify the most cost-effective changes to achieve throughput increases.
We extensively analysed past operating data to gain a clear understanding of the operational performance that IOC has achieved to date.
Since 2006, we have carried out numerous studies using this simulation model.
Our simulation model of the system included the following components:
In this system, there were clear trade-offs between investments in infrastructure or train fleet to meet operational goals. At various throughputs, a financial analysis was prepared to compare the present value of capital and operational costs for various alternatives to determine the optimal investments.
