Analysis and Data Mining of Lead-Zinc Ore Data 275 The difficulties to efficiently treat relatively low-grade, refractory-type ores require development of intelligent models to analyze and predict the ore content and grade. In our study we use clustering of the Pb-Zn assay data to create a data mining model for segmentation and prediction of Pb

A comparison of an average grade by ore type mined reveals marked differences. The highest average nickel grades are contained in saprolite ore produced by nickel laterite miners at 1.6% in 2015, followed by limonite producers, with an average grade of 1.14%. The average grade of all nickel sulphide producers in 2015 is forecast to be 0.64%.

Highlights There is no apparent connection between average ore grades and deposit size, although head grades are inversely related to the tonnage of ore mined. Head grades have tended to exceed reserve grades, but have been falling closer to reserve grades in recent years. There is some evidence of an inverse relationship between prices and head grades.
