Show BLUESTONE COMPANY BUILDING NEW MILL Ycrington Property, Which Was Improved Im-proved Last Spring, Now Has Flota-tlon Flota-tlon Plant Under Construction. The BluesLone Mining and Smelting company's property at Ycrington is a very busy place again. Uast spring the company com-pany made so many improvements to the property and shipped so much ore to the Mason Valley smelter that other smaller properties could not be served. Now the company is erecting a flotation plant largo enough to handle 400 to BOO tons dally. There are already completed two large buildings, connected by a transfer S stem. The first is the milling or crushing plant, where several Hardlngo hall mill "rushers are now. being Installed. They are known as gyratory crushers. The plan iB to transfer the finely i rushed ore to the flotation plant, where it will be treated by what is known as the ytlmpson process. The machinery Is on the ground and rea-dv for installation, except, a few small motors. The officials expect to have the plant in operation about April 1- The mine has been shipping on an average of 700 tons daily to the smelter since Christmas, so that when the new plant Is operating there will be an output out-put of 1200 tons daily. This large output is possible -with about 130 men in all departments. The gravity svetem has been consistently and successfully suc-cessfully applied. Through a long tunnel that, runs under the glory hole, cars pass (o the loading point and are filled from what appear to be great bins by simply opening the chutes. The ore is then hauled out by electricity elec-tricity a mile, perhaps, and dumped into large pits, at the bottom of which there is another tunnel where the cars are loaded for the smelter, as before. From near this latter point a switch is being laid, so that the cars from the mine can be dumped into the mill, where gravity again carries the ore downward from one machine to another. In passing to the flotation plant, the ore is, elevated, so that once more a downward course carries it to the point of concentration, where it is ready for shipment. The engineering arrangements are simple in general plan, but worked out with great care, so that electricity and gravity do the work of hundreds of men and horses. A number of cottages have been erected erect-ed for the men with families, and the hoarding house and cabins are all in good condition, in harmony with the neat i homes and the well-kept and commodious offices.
