PRIDE OF THE WEST
Description of the Company's New
 Reduction Plant.

Friday of last week the Oasis man paid a short visit to Washington Camp and Duquesne, going over IhursdaS evening with J. s. Scoby, general man. ager of the company which is operat- ing the Pride of the West mine, the Pool group, the Holland mine ana other properties in the vicinity
 Two or three years ago fine reduc- tion plant sufficient to handle forty tons of ore daily was erected ana oper- ated until October l of last year, when it was removed and there was erected in its stead a much finer and larger plant with daily capacity of one hun dred tons of ore, which was started up about a month ago.
 Friday morning the scribe was kind ly shown over the plant, which is cer- tainly one of the finest anywhere in the country.
 The power is supplied by a fine big 25O horse power high speed Corliss en- zine, with speed of 120 revolutions per minute, made by the lis-Chalm- CTS company. The engine drives all the machinery and two dynamos, one of which supplies juice" for the cleo tric concentrators, the other for the lighting plant, lights being furnished not only where needed in the plant but elsewhere in the camp.
 The process used is a combination of electric and water concentration and smelting in reverberatory furnace. Coming from the mine the ore passes through the usual rock breaker and is then curshed by Cornish rolls. From the rolls the pulp passes to a hearth roaster, where it is kept continually stirred by automatic travels" travel ing the full length of the hearth upon light double pulleyS running upon tracks at the sides of the hearths, and drawn by sprocket chains. At the end of the hearth, which is about one hun dred feet long and twenty feet wide the ravels carry the roasted pulp over the end and drcps it upon the cooler below the hearth, where the ravels carry it back to the other end of the cooler, there raising to again pass through the hearth, stirring up and dragging through more pulp. From the cooler the pulp falls into hoppers upon broad belts, where it is automati- caliy spread the full width of the belts and to depth of about quarter o1 an inch. These belts pass closely be- meath big magnets, across the faces o which run other broad belts. The cleo
 
 copper particles out from the pulp, ant they adhere to the under side of tn. belts passing over the faces Of tn, magnets, until they have passed be yond. As soon as the magnetic attrac tion ceases. the copper falls from tn belts upon long carrier. which con veys it to the reverberatory furnac at the other end of the building
 From the electric concentrations fb pulp passes to a series of Wilhey con centrators GA R. Wilaey, the invento and patentee thereof, being one of tn principal owners in the enterprise where by water process the zinc an, lead and silver are separated Apd tn lead and silver concentrates are PAsse off and saved at one table and the gin 1t another-the tailings going out a the dump So complete and perfect the process that hardly more than on per cent of the values escape with tin tailings.
 The copper concentrates go to tt reverberatory furnace. which has daily capacity for handling fifty tor of concentrates. producing a hig grade matter, running from 50 to per cent in copper.
 From some of the mines in the Pc group there are now coming fine ca bOnate ores which go directly to u furnace, being mixed with the conce. trates.
 Converters have been ordered and soon as they arrive and are set up u molten matte will be run directly fro the furnace into the converters, ar the product will then be metallic co] per about go per cent fine.
 The lead and silver concentrates ar the zinc, as they come from the table are dried. sacked and shipped.
