Show university REDUCTION WORKS state school of mines plant will soon be in operation within a fortnight the large mill at the university of utah will be running to its full capacity with the exception of some slight changes in the arrangement of the cyanide part of the plant the work vork of remodeling the mill is for the most part completed ever since november last says the daily tribune this work has been going on and before all the contemplated changes are carried into effect approximately will have been expended the work of remodeling has been carried on under the direction of prof gustave A who has a wide and varied experience as a designer of mine and mill plants when completed the mill in the opinion of mining experts who have recently visited the institution will be without a peer in the world as a concentrating cent rating plant this extensive remodeling is due to two causes the most important was the addition of the st louis plant which was given to the university by the utah commission at the close of the fair to make any practical use of the st louis plant it was found necessary to make a number of alterations in the university mill then again the mill completed at the university over a year ago was found to have a number of rather serious defects when put in operation con at the suggestion of dr merrill and prof it was decided to entirely remodel the mill the st louis plant has been installed so that it can be operated separately from the large plant using only the large crusher and elevator As such it serves excellently for making medium sized tests if necessary the st louis plant can also be used in conjunction with the large mill originally the st louis plant was intended merely for show and so in order to make it of practical value in test work prof has been under the necessity of entik entirely ely rear re ar ranging it completed it stands a marvelous little mechanism the machinery of the large mill has been entirely rearranged the water tanks have been raised from the borund floor to the very ceiling formerly the machinery and the tanks were ail on the same level now the elevator has been raised as high as the building will permit so as to allow plenty of fall and also to enable the student to feed automatically mati cally from any one of the screens onto the separating machines without resorting to buckets the machines have been arranged so that the ore from a former test is conot not apt to be mixed with that from a subsequent test all the receptacles have been arranged so that the mill can be easily cleaned up by simply turning the hose oh the floor without disturbing the products of the mill the launders which were formerly above the floor have been sunk into the cement and the floors have been lined with glass better drainage facilities have been provided and the machinery has been separated so that it can be worked conveniently and without danger the settling tanks have been separated into five compartments as compared with two before As the machinery was formerly arranged it was very difficult to move about at times it was necessary to almost crawl now it is possible to move around easily and work machines side by side formerly there were vere two floors with narrow stairways now there are four with broad stairways which are fenced off so that there is no danger of the hurried student falling the present arrangement ran gement provides six feet of head bead room all over the building As it now stands the mill is capable of handling the following processes concentration in all its branches cyaniding cyan iding chlorination amalgamation roasting smelting smelling sm elting cement grinding and fusing or any combination of the abovementioned above mentioned processes it is intended to add to the mill the electrostatic and magnetic separation processes later lack of funds prevents the moving of the coa coarse arse jigs from the first to the second floor the present arrangement of the mill is this material is taken from the crushers on the ground floor by the elevator to the screens on the third floor from these the ore is passed into the hydraulic classifiers or the settling tank on the second floor from any one of these machines the ore can be automatically drawn onto the separating machines below this system enables the student to test the value of the different separating machines on the various ores tested students have been working in the mill on parts of the machines for some weeks yesterday the major part of the mill was thrown open to the engineers and a large number of the students were busy in the mill all day A number of the seniors are anxiously awaiting its completion as they must use the mill to make tests in the preparation of their theses |
