Show TO A MAMMOTH MILL daily call lead S D the horseshoe mining company after deliberate and full investigation has f finally decided on the character of the big cyanide mill and method of its construction and the plans have been executed with the exception of certain details not yet fully determined the mill will be wet crushing with stamps I 1 constructed on the terrace or gravity plan the machinery will be placed on the south erly slope of the hill north of the KiJ donan mill and the tank structure will be located in the valley of whitewood creek immediately below on the comp company anys s mill site at pluma one mile northeast of this thid city the pulverizing battery will consist of stamps arranged in two rows of thirty double discharge mortars in each row sixty mortars in all with the usual complement of five stamps to each mortar of 1000 pounds weight per stamp two no 71 gates rock crushers will be located on a bedrock bed rock floor above the stamp batteries the batteries will occupy a frontage space on the hill of feet the iron structure that will enclose them will be somewhat longer the boilers and engine will be located in a separate building adjoining and will have a capacity of horsepower horse power the burlington tra track ck will be extended around the hill without to the top of the mill and the ore cars will pass over and dump into the crusher bin the ore will be drawn from this bin through chutes to the rock breakers the crushed I 1 ore will pass from the rock breakers into an immense storage bin running the entire length of the batteries feet the bottom of the storage bin represents a right angled triangle apex ing midway between the two rows of batteries and is designed to accommodate each row of batteries by delivering an equal quantity of mixed ore to each this is arranged by means of a distributor extending along the pinnacle or apex of the bin which receives and distributes the ore equally on each side or to each compartment of the bin from the sides of the base of the storage bin the cashed ore will be drawn into feeders which will deliver it automatically to the double row of mortars from the mortars the pulp and slimes will be laundered and piped to the leaching and slime tanks below such is the general system contemplated by the plans it operates automatically and by gravitation there is no shoveling or of the material or elevating machinery to break wear and be repaired the system is simple and economic without complicated machinery and represents the very minimum expense of handling and crushing rock the tank room will be situated on a level plat at the base of the hill below the crushing machinery this building will be feet and will contain twelve leaching janks tanks six feet deep by fifty feet diameter having a capacity of tons each and six slime tanks twenty feet deep by fifty feet diameter with t a capacity of 1833 tons each also three tion tanks feet the whole works from base to apex will have an elevation of over feet when completed the horseshoe company will operate the largest cyanide mill in america or in the world so far as any record is now known the tailings plant of the homestake Home stake company three quarters of a mile up the gulch is conceded to be the largest known of its class it treats 1200 tons daily and has a total leaching tank capacity of tons the golden gate mill of the consolidated mercur company of mercur utah claims the worlds banner in capacity outside of the tailings mills the mercur mill as per last report report of the company crushed and treated an average of tons per day it has twenty six leaching tanks of tons each giving a total capacity of tons and claims to have a capacity of 1000 tons per day the mercur ore is a lime liale gangue is crushed to only i about one fourth to one eighth inch mesh whereas the horseshoe ore will require pulverization of ten to sixteen inch mesh the gigantic gantle ai horseshoe plant will have a crushing capacity on its ores of 1200 tons per day and a leaching tank capacity of 1700 tons the horseshoe will easily outrank the mercur in capacity and will have a mill somewhat in proportion to the mountains mountain 9 of ore in its vast mineral domain and so the worlds banner for the largest ore reducing cyanide mill will hang high on the rocks of pluma hill |
