摘要：
The chain of the bauxite and alumina business in terms of quality, costs and longevity is critical for the mine and refinery installations. This paper describes the impact of the size of the mine according the bauxite quality required by the Refinery, the influence of level of knowledge of the deposit on life of the mine, and finally, some scenarios changing the some economic factors, such as prices on the bauxite. So, there are several scenarios, which could help the decision maker to get the best solution joining the financial, quality and other strategic issues. Beside this, each scenario results gave a better understanding of the business risks and opportunities to improve the results.
