!K0EIG PROCESS IS WiDELYUTILIZED SpeciaJ to The Tribune. BUTTE. FoN. 2. Malcolm H. Carpenter, jcliief ensnneer for the Koerin? Cyanid- ing Process company of Salt Lake City. 'spnt Friday In Butte In consultation j with the officials of the milling Development Devel-opment company, which is to install the Koering process at the Gold Dyke group i near Salmon, Idaho. Mr. Carpenter was on his way to Salt Lake :rom Sheridan, Mont, where ho had Just finished superintending the etartlng up of the Investors' company's new cyanide plant. This company, after a most thorough test on their ore?, adopted and installed the Koering process, making a complete change of the old system at an expense of $34,000, putting in electric power, new crushing equipment and machinery. ma-chinery. The present capacity of the crushing equipment is from 100 to 120 tons. The company has ordered another Koering drum, to be delivered ahout next July. which will bfiing the present cvanlding equipment up to the same capacity ca-pacity as the crushing machinery. The flow sheet now In use was worked out last year by Mr. Carpenter and Manager Frank J. StaraJ during a six weeks' run. using the Koering proce. and using for crushing coarse battery stamps crushing to thirty mesh. It was after this mill run that the company decided de-cided to re-equip the mill. The Koering company has arranged to install a 400-ton plant for the Drilling Development company, a Montana corporation, cor-poration, at the Gold Dyke property, east I of Salmon. Idaho. This property is a big ! porphyry dyke, with an enormous devel-i devel-i opuient of very pood commercial ore. i which is very similar to, thought not po complex as. the riheridan ores. The Drilling Drill-ing Development company has been ' watchlnz very carefully the result of the run on the Sheridan ores and as a con-r con-r sequence is elated over the success of i the Koering process there. While the i Gold Dyke ores have been very thor-; thor-; oughly tested by actual runs by the Koer-; Koer-; ing company, and extraordinary results ; have been obtained, yet to know of such good results on a larpe tonnage run on I similar ores is an incentive to speed up j their efforts and get their mill In operation opera-tion at the earliest possible moment.
