Show THE BLOOM DRY WASHER gold separator that promises great things for placer mines record helena mont articles of incorporation of the gold separator company have been filed for the purpose of starting the work of manufacturing the bloom dry separator patented the invention relates to apparatus for separating native gold in the form of small nuggets flakes and grains from sand dirt gravel pulp etc by means of screening and the use of an air blast in connection with suitable receiving devices in which the gold is caught owing to its high specific gravity bach wright attorneys for the company made the following statement in regard to the machine we believe that this machine will revolutionize lut ionize placer prospecting and will open up many valuable placer mines especially in arizona utah idaho and the klondike which could not heretofore be worked owing to the lack of water we have had expert mining men m en give the machine the most severe tests and it will absolutely do the work the machine has been tested in every possible way it has been worked on the same ground a set of prospectors were working one man with the small pros pecking machine took the same amount of gold in a limited time as was secured by four prospectors washing with the pan we have tested it upon the tailings north of the city where there is scarcely a color to the pan and upon every test the machine showed more colors than the pan excepting one and upon that one both the machine and the pan showed one color the highest number that could be secured by the machine was twelve the finest gold dust has been mixed with sand gravel dirt nails steel dust and clippings glass etc and the machine picks out over 90 per cent of it these machines will be manufactured in the city of helena and will be of various sizes the smallest machine is called the prospector machine this is a little hand affair which can be easily carried around the country and with it the prospector can prospect anywhere regardless of water and can run three or four times as much dirt as one man can pan and with much less labor all that is necessary is to shovel in the dirt and turn the crank there will also be manufactured a larger hand machine and larger machines will be constructed ted to order of course where a company has plenty of water this machine will probably be impracticable as water is the most economical method of handling placer gold our company expects to put a guarantee upon the machine to take at least 85 per cent of the gold and unless the conditions are most unfavorable it will take over 90 per cent but there will be an expense for power and handling the dirt from this machine which is avoided by hydraulic workings so that where hydraulic workings are possible it is fair to say that this machine will be impracticable however in those rich workings where the water can not be secured without great expense and for the prospector everywhere we claim that the bloom dry separator has no equal it is not a machine that crushes rock but it merely rolls the stone gravel and sand around so that there is very little friction or resistance and very little power is necessary we estimate that a two horse power gasoline engine would run a machine large enough to keep five or ten men at work there is one other feature to which attention should le be called this is not one of the kind of machines where dirt must be baked until it is powder dry before the machine will take hold of the gold dirt can be shoveled right from the earth it if the ground were soaked with the water the machine would not get so much gold and of course the dryer the dirt the bigger the percentage of gold obtained but excepting a da day y when there is a heavy rainfall the dirt can be handled right from the earth it requires no preparation or handling or sorting of any kind the machine will catch the nuggets and dust no matter how fine and there is a device to catch flake gold which will go over in in the washing process |
