6.1 Process Overview 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.

Process mining is a set of techniques used for obtaining knowledge of and extracting insights from processes by the means of analyzing the event data, generated during the execution of the process. The end goal of process mining is to discover, model, monitor, and optimize the underlying processes. The potential benefits of process mining:

Lead is extracted from ores dug from under-ground mines. More than 60 minerals contain some form of lead, but only three are usually mined for lead production. The most common is called galena.

The purpose of processing was to transform raw lead ore extracted from the vein into pure lead. This involved many steps. The first was to wash, sort and dress the ore. Initially the process was very crude, often done by women and children. There was no crushing machinery, and no mechanical sieves. Just hands, hammers and water.
