Abstract

This paper focuses on obtaining Control Charts in the study of the process of characterization of nickeliferous samples, which as part of the internal quality control (CIC), has been carried out to ensure the control of the variability of this process, and allow the delivery of reliable analytical results. The essential results are the databases built on the characterization of the Internal Control Sample of nickeliferous ore and the Control Charts for the three independent variables studied (% Ni, % Co and% Fe). Implicitly, and in order to arrive at the results, it was necessary to study and graphically formalize the behavior of the measurements in the sense of adjusting the normality and frequency of the results of each variable. The information processing was carried out with the help of Statgraphics and Minitab systems.
