Vale’s biggest operation, the Carajás, is an integrated mining complex located in the Amazon region in northern Brazil, producing over 230 Mtpy. Many decisions and assumptions in the activities of a mining complex of this size will affect system operations. This may result in a deviation from the optimum production sequence over the life extraction of the business and thus, a reduction in NPV. Discover how Deswik’s tools make it possible to develop a life-of-mine using a blending strategy integrated with a haulage model, ensuring operational control and production and qualities targets.
