: ANALYSIS AND DATA MINING OF LEAD-ZINC ORE DATA

2017-2-10 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 ...

2013-11-8 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
