| Show THE DOUBLE concentrator the mining review enjoyed a visit last week from miller borglum a prominent citizen of butte montana mr air borglum is the inventor and patentee oj of the double concentrator a concentrating machine which promises much and which in its is eliciting much favorable comment among fillmen and those familiar with the work and operation of concentrating tables of standard make during his stay in zion alon mr borglum had bad a model of his machine on exhibition at the uptown offices of the salt lake engineering works in the dooly block and quite i a number of prominent mining men and experienced fillmen took advantage of the opportunity of inspecting its workings and methods of operation in a small pamphlet descriptive of the double concentrator the inventor says this marvelous machine has been named the double concentrator because it has a double motion longitudinal and lateral and it practically does double the work of any other similar device now or heretofore known in the mechanical world the double concentrator is an unusual an extraordinary machine because it weighs no more costs no more requires no more room nor power per machine to operate it than other tables but on the other hand it will do practically about double the work of any other concentrator now known to the mining world this is not an idle boast as will be demonstrated by reading the testimonials under this cover this double result is accomplished by and through the double movement of the double concentrator back and forth and side motion a veritable hand panning process this dual motion is effective and absolutely sol accomplishes the marvelous results that have thus made a new and startling record in this line of industry everything goes by comparison and the only comprehensive way in which to grasp the merits of the double concentrator is to note its actual results it will be seen from the statements of those who have practical knowledge of the concentrating business and who have actually operated this machine at butte montana that its real feal capacity is as claimed these are big figures but facts are facts we want the closest scrutiny of our statements we claim for the double concentrator table able it will handle successfully about double the material of any other known table of today it will make cleaner and more valuable concentrates than any other machine known it requires practically no attention after it is once set in motion to get its best results skilled labor being unnecessary either in its adjustment or operation it saves at least 50 per cent of the room and power required by the best other tables it is so constructed as to almost annihilate friction thus insuring the greatest possible durability absence of repairs continuous operation and hence cheap operation it wil treat any and all kinds of ores that any machine can with the same relative results in every case it will save half the original cost of tables half the freight half the labor of setting up and operating and less than half the repairs of any other known table associated with mr borglum in the ownership of the patent for the double concentrator cen are J H curtis and green majors wealthy butte citizens so that no trouble will be experienced in the manufacture of machines and the placing of them upon the market which will be done shortly the only question now debated by these gentlemen being as to whether they will engage in the manufacture and building of machines for the trade or let out this branch of the business on a royalty mr borglum is now in denver interviewing machinery dealers and manufacturers and will soon arrive at a conclusion as to the best methods to pursue in the handling of his concentrator he is a nephew of charles 0 michelson of salt lake the inventor and patentee of a new gold saver mention n of which was made in the last issue of the mining review |
