Análise de viabilidade da implantação de dois cenários de transporte na mineração Onça Puma - Vale S.A., Ourilândia do Norte, Pará

Abstract

Mining enterprises, in its conceptual stage of the project are developed on the basis of production scenarios. Several variables are applied in the preparation of the operating conditions of these scenarios. An economic analysis well prepared to take strategic decisions aiming to improve the financial performance of the company. THE Onça Puma Mining /VALE S. A. presents a demand for analysis of two operational scenarios of transport of the ore of nickel between intermediate courtyards of storage: the transport by trucks and transported by conveyor belts, with the objective of defining what the method of transportation more viable. For both, were studied the traditional methods of analysis of financial viability, such as: VPL - Net Present Value, Discounted Cash Flow, which are usually applied as tools that facilitate the decision-making process. These approaches, was incorporated into a statistical method of simulation called Method of Monte Carlo, which allows you to use probability distribution in the composition of operational scenarios. The equipment involved in the analyzes were duly selected and its operational costs and investment based on information the company's internal, being possible the constitution of the cash flow of each of the scenarios. Thus, the analysis of probability distributions for the NPV of costs of the scenarios I and II showed that in 98.5 % of simulations carried out the transport with belts and the alternative more economic for the application.
