Show general engineering company magnetic separators installed at the works of the general engineering company pierpont street this city two new magnetic separators have recently been installed and are now in running order for the various ore tests with this latest addition the plant is now fully equipped to make exhaustive tests in the treatment of ores the business of this concern is to make tests upon all character cha rafter of ores and determine the best and most economic treatment of the same it caters exclusively to custom trade and is operated independently of any machinery house of the city the plant the plant occupies both floors of the settling tan tanks ks and magnetic separators in the cyanide department are the agitating and leaching tanks slimes separator and a kelly filter press four wilfley tables and six callow settling tanks complete the equipment in this part of the building to this arrangement two new magnetic separators have lately been added these are of two types the ding and the erill the former is a low and the latter a high potential machine in the ding separator the ore or concentrates are fed into a hopper at the top of the machine from here it falls upon an inclined surface the I 1 motion of which spreads the material out and slowly moves it toward the bottom 70 p A 0 WJ k 7 plant of the general engineering co lower floor building and is equipped with milling devises of every description the fine crushing is done in a huntington mill and the product run upon the plates for amalgamation from here the material is run upon a pierce riffle which has proven to he be a great success in saving the values crushing for the big plant is done in a set of dodge crushers and is then hoisted to the top of the building by bucket elevators from here the ore is sent through the plant as in an ordinary mill on the top floor are located the crushers the jigs and the screens the jig glug department part ment includes one wall jig and three compartment jigs all adjustable to meet the requirements of various ores here also are found a complete set of callow screens from sixteen to mesh on the basement floor are found the cyanide department concentrating plant filter press the motion and speed of this surface may be adjusted by regulators immediately over this surface is a very powerful magnet and a horizontally revolving wheel agthe As the material passes within the magnetic field the revolving wheel picks up the magnetic particles when beyond the influence of the magnet the particles fall from the wheel into a hopper below the residue passes along the surface until the second magnetic field is reached where the process is repeated thus the magnetic iron Is removed from the lead and zinc which is afterwards separated by gravimetric methods the ore is often given a preliminary roasting before treatment in the separator the works on the same principal but with different mechanism the material is conveyed through the magnetic field which is very powerful on a travel ling belt and is subjected to practically the same treatment as in the ding both machines are very efficient and their installation has added greatly to the plant the general engineering company is is supplying a long felt want in salt lake and are able to ascertain just what methods me thodis applicable to the treatment of different ores the company is officered and conducted by some of the most able engineers and metallurgists in the west J M callow is 7 11 19 1 A SO 4 wa k aa I 1 A LJ V 4 k plant of the general engineering co upper floor has spared no effort to make its plant one of the most complete in the country to the man who is contemplating the erection of a milling plant their services are indis pen sible with the facilities at hand they president and manager jas jaa W neil vice president geo M bacon secretary and treasurer ermest bernest gayford superintendent and frank P callow director |
