Show UTAH COPPER MINES WITH STEAM SHOVEL . Undorground work in the greal Utah Copper mine at Bingham hai been almost discontinued, and within a few weeks .will be entirely abandoned. aban-doned. Colonel D. C. Jackling said yesterday that this is a result of the advanced stage reached in the stripping strip-ping operations, which makes It possible pos-sible for the steam shovels to provide pro-vide oven more ore than the combined com-bined capacity of the two mill plants require Heretofore it has kept the mine and the railroad hustling to keep the two mills working up to capacity, but now the situation i6 reversed and the mine is able to furnish the mills more ore than they can handle. Connections Connec-tions have been made on all the levels, lev-els, which almost encircle the mountain moun-tain of ore. A direct haul can be mado"from all the pits, and the ore is easily broken down at the rate of 23,000 tons daily. More ore can be provided for the mills at any time arrangements ar-rangements are made for the concentrators concen-trators to increase the present capacity. ca-pacity. The average grade of the ore being produced at this tiihe is better bet-ter than it has been, the top portion of the lo'-grade mineral-bearing zone having been worked off. Utah Copper a few years ago began operations with the idea of supplying supply-ing ore for a GOO-ton concentrator. Later La-ter the Boston Consolidated properties proper-ties were acquired and with this a 3000-ton mill. This mill was re vamped and under the same roof the management has been able tojbrlng Its capacity up to 9000 tons dairy. More modern appliances have been installed in the company's original mill at Magna, with the result tha( its capacity ca-pacity has been more than doubled, for it has been found that with certain cer-tain characters of ore the Magna mill can treat 14,000 tons daily. Thus since production began It has been a problem with the Utah Copper Cop-per to catch up with its ever-increasing mill capacity. Now that this work has been accomplished, the question that suggests itself islwhelh er or not the company will consider it advisable to again raise its mill capacity. It is not believed any attempt at-tempt will be made to do this, at least not for a time. ' oo |
