Tncre are many surprises being experienced expe-rienced by the mining companies of Bingham Bing-ham In the treatment of the low-grade porphyry ores. The Utah Copper and Boston Consolidated "mills at Garfield, for Instance, are having their capacity doubled dou-bled by tho addition of less equipment than could have been foreseen prior to actual milling operations. Another mill treating tho low-grade Bingham copper rock, the Ohio Copper plant. Is setting a pace which the management could not havo safely predicted when tho plant was designed. To Tho Tribune yesterday. Engineer Al Frank, who la looking after the Interests In-terests of the Ohio Copper In the absence ab-sence of General Manager Colin Mcintosh, Mc-intosh, said that while the Ohio mill as now constituted had a logical capacity ca-pacity of 1000 tons of ore a day, on Wednesday 1800 Ions of ore wore sent through the mill. This splendid record Is not due to Improvements In tho equipment, equip-ment, but lo tho ability of the mill to take the rock and treat it. Naturally, with tlmo any company will learn by experience ex-perience where here and then: this or that can be caught up or let out. to advantage, ad-vantage, and to Mill Manager William Kidney, Mr. Fran; gives all credit for knowing the Ohio mill and talcing advantage ad-vantage of Its strong spots as they are developed through the lessons learned from actual operation.
