NEW COPPER PROCESS.

Referring to the gradual development of the copper industry in the north. the one factor in the solution must be con cCded to be MT. W. L. George. This gentleman has undoubtedly solved the problem of handling the very lowest grades of copper ores. Mir. George has spent two years experimenting with this low grade carbonate ore near the Grand canyon. When positive of his experiments himself, he brought the matter to the attention of the Anita Copper company. That company spent five thousand dollars in further proofs and experiments last year. Finally Mir George was sent to Denver, where he supervised the manufacture of the new machinery required. This machinery is now in place in the Williams shelter and the first big run will be made this wee!,
 The process is extremely simple, and yet chemists have spent their lives try ing to discover the same thing. With out employing any technical terms. or going into theory in ths metallurgical realm. it is 2u explained by saving that q common smelter stack is fur nished with q converter. By the side of the stock are built two brick and steel furnaces or stoves. Ore and coal are burned together in the stack. Wood alone is burned in the heaters, and this fed down two stacks from above Heat sufficient to convert the ore in the rock into metallic form. and not sufficient to turn the rock into slag. is applied. This drops through the perfo~ations fH the converter down below. and from the bottom of the stack is kicked out into a steel lined cooling pit by q steel plunger. This plunger is regulated by contracting and expanding gauge wheel from above, which can be regu- lated by one of two levers, and the plunger either made to go fast or slow. This gauge wheel itself is a wonder. and is the first and only one of ifs kind ever made. Steam jets play into the furnace for the purpose of ganer- atlng oxygen. From the cooling pit the burnt product is taken by bucket ele- Vators to the crusher. and is there fed automatically into the crusher After passing through the crusher it passes number of blowers in it's descent. and much of the waste is blown out. Then the product is again picked up by bucket elevators and is fed into power ful rollers set e-thirty-secOnd of an inch apart passing a successing Of blowers again. It is then deposited on the first of set of three screens. The rollers have pressed all the metal into sheets. The debris is pulverized so fine that U goes through the screen and is blown away by the air from the blow CTS. The larger screen catches the larger globules of copper, the second screen the next in size. and the last screen catches the bits of metal smaller even than pin head. The process will tleat any kind of copper ere. All the great amount of help around a smelter IS done away with, as the rock after being fed into the converter is not touched again, until it comes out copper ca the screens. All patents are held ana controlled by Mir. George and the Anita company. This discovery. means much just now for this part of the ter rltory as it means the treatment of all this huge deposit of low grade con- per ere, which lies in a blanket forna ton between Williams and FIagsta if and the Grand canyon. It means in the near future also much more to the investors in the copper world. but of that subject more anon. as the length or this now probably exceeds the cour- tesy of your request
