Show NEW GOLD amalgamating MACHINE writing Z from philadelphia under date of nov 0 L mcgrew of mcgrew bros land merchants and evidently mining promoters takes occasion to declare that a 1 f I old mining minin revival is on in the southern states particularly in virginia north carolina south I carolina arolina and georgia but where heretofore herto fore it has not been possible to save much more than one third of the values because the old is so fine that much of it escapes as slimes and rusty gold which runs over the plates ar mr mcgrew believes that the south as a gold mining country is again going to be placed on the map as a result of the performance of the jobson centrifugal amalgamator iab ga mator a photo of which he sends with his letter and which is reproduced here so that the reader may form a better idea of the mechanical features of the invention ven tion mr mcgrew says 9 this machine has been tried out in a number of places and on most all kinds of old tailings and is guaranteed to save 95 of the free gold in any ore as it saves the fine flour float and rusty gold the machine has been working during the last four months at candor N C on tailings we have been there and have seen it in operation and so have quite a number of good mining engineers and some of the best men with a pan in this country and they all say the machine saves because none of them have been able to find a color behind the ma machine maclaine cliine they declare it saves the gold as fine as smoke when the machine is running there is a band of mercury around the top of the lower bowl the ore i is s pumped through the machine at about 5 lb pressure using about 80 water the speed of the mill drives the gold into the mercury the gold that does not amalgamate is held in suspension back of the mercury and when the plugs are opened all the gold comes out together there is no waste of mercury in operating the machine can be cleaned out in about ten minutes and made ready to start again ane machine handles from 3 to 5 tons per hour and does not clog as in tailings they run them through about ls 1 inch screen ever everything y thing that goes through 6 the screen goes through the mill and when they clean up they dont get more than ten pounds of stuff about the only thing that stays in are nail these dont get through we are not interested in this machine in any way only we think its merits and possibilities should be known to all gold mining men we are interested in selling properties and have several good ones for sale but since this machine has proven to be a life saver for saving gold slimes we have purchased a property and are going to mine as as well as sell mines we only hope this information will be the means of helping belpin gd out mining men that are losing the greater art aart of their gol gold |
