Determinação geoestatística da distribuição espacial da propriedade alvura do caulim da mina da Pará Pigmentos S/A

Abstract

To ensure a quality product in the processing and marketing of kaolin is important to have a quality control from mining, the company Pará Pigments S/A kaolin extracts with different levels of property that governs the operation is ISO brightness where issued blocks are allocated to various storage batteries. In this study tests were done to determine the brightness of kaolin in situ of Mine Ipixuna Pará - PA and drew up a map of the spatial distribution of this parameter by interpolation by ordinary kriging. The results proved to be efficient for geometric modeling of the mineralized body being an effective tool in quality control in ore mining, specifying good quality sectors, optimizing the block model to be drawn up in accordance with the needs of the plant, having a good similarity to the reconciliation between the values moved on till the values calculated in the model, contributing to an effective improvement of the management of the mine planning short term.
