Case Study: Iron Ore Let us assume that we have the same energy consumption. We also assume that the material stream into the processing plant is the same as before (500 t/h). However by using the OSX we reduce the concentration of waste materials in the feed. By increasing the material stream out of the mine (with the same 30% fraction of waste material), we can increase the production capacity by 37%. In addition we reduce the waste disposal after processing by 87%. Results: Energy consumption reduction: Waste disposal reduction after processing: Reduced transport requirement from the...
