The WISCONSIN ENGINEER 285 THE WORK OF THE MINING ENGINEER R. S. MCCAFFREY Professor of Mining and Metallurgy The work of the mining engineer which, broadly speaking is the extraction of mineral from the ground, and its preparation into a marketable product, may be divided into three separate parts,-mining geology, mine engineering, and metallurgy. These three fields though closely related require a distinct train- ing and it is hardly probable that one man can become proficient in all branches. The work of the mining geologist takes up the geological ex- amination of new areas and the detailed study of the geological conditions to obtain data for the future exploitation and devel- opment of the economic resources. The geologist is very often retained during the mining operations to continue geological studies of the structure and genesis of the ore bodies, and some of the most important work of our graduates is in this line. After a deposit of mineral has been discovered and prospected, it is then necessary to extract the mineral economically. Just to give an idea of the magnitude of certain operations of this kind, it might be stated that the excavation in the Mesabi iron district, and this only in one mining district in the United States, was vastly in excess of the excavation for the new Pan- ama Canal when the latter was at its maximum, and was done, too, under the economic limitation that the work must be carried on at a profit-a limitation that did not prevail at the Panama Canal. Some of the larger copper producers handle enormous tonnage daily. The Utah Copper Company produces 25,000 tons every 24 hours, which shows that large operations are not confined to the iron producers. Our graduates who are in the mining part of the work, are now employed in various iron, copper, lead, and gold and silver camps of the United States, and as the mineral development of the past few years has been tremendous it is absolutely impossible to commence to suply 1-T taco Homd for graduiates in this line. ;!LppJly bl U.., u |w - , ,t,->.-- ;, i__. _ The metallurgist takes the ore after it is brought to the sur- face at the mine and concentrates and separates the valuable
