摘要：

In this study, two types of control charts have been used to show the effect of autocorrelation (AC) to determine process stability of Espey and Hisarcik Colemanite concentrators. Individuals Control (IC) chart has shown that both concentrators are statistically out of control. On the other hand, according to Special Cause Control (SCC) chart, which considers impact of AC, only Hisarcik concentrator is Out of control. SCC chart has been found more appropriate for autocorrelated data since it provides a higher probability of coverage than IC chart.
