A Real-Time Ore Proportioning System in a Large Open-Pit Copper-Molybdenum Mine

This paper introduces a new technology using a new mathematics model to solve the blending problem of two or more kinds of minerals, which grades are very different even in orders of magnitude, and creates a blending system which can produce an optimal program of blending automatically using a feedback process based on Surpac, a mining software, and achieves a real time truck dispatching system finally. All of above can improve quality and quantity of the minerals blending stably, that has been proved in practice. According 2001s record, this system had the Cu grade amplitude down from 10.54% to 3.72% and the Mo grade amplitude from 6.49% to 3.11%.
