1 INTRODUCTION TO MINING 1.1 MINING'S CONTRIBUTION TO CIVILIZATION Mining may well have been the second of humankind's earliest endeavors— granted that agriculture was the first.

Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining. A zinc mine is a mine that produces zinc metal. Some mines produce primarily zinc, but some mines produce zinc as a side-product of some metal that has a higher concentration in the ore.

The Auby smelter is a mid-scale electrolytic zinc smelter. It produces cathodes as finished products, rather than casting into ingots. Feedstock of both zinc concentrates and zinc secondaries is consumed at the plant using the RLE process to produce zinc cathode.
