The Mining and Scientific Press, Hungerford Improved Concentrator, for Saving Gold, Sulphurets, There is no description of machinery of so much importance to the mining intcrest of California, at the present time, as that for the separation of sulphurets. Mines are now ahandoned, or, what is worse, paying assessments which, if the sulphurets were saved, would yield handsome dividends. Great difheulty, owing to the varied form and character of the sulphurets, has heen experieuced iu devising a machine to separate them, and it is only by close and patient observation, persevering study and careful experiment, that any machine can be made or matured so as to save a high per centage of the sulphurets which are in the ore. No machine is so perfect as to save all; and the best is that which will save most with the least expenditure of time, mouey and power. Many machines have been tried, and many abandoned ; all of which have heen unable, so far, to attain a profitahle separation, and meet the requirement of the mining interest, so well as that now patented hy Mr. Hungerford, which is an improvement on the well-known Hungerford & Prater Concentrator, with whicb his name is already so familiar. The separating or concentrating action is obtained hy centrifugal force and gravitation; the pulp being preserved by water in the proper condition for tbe operation, and the pan so constructed, mechanically, as to ,allow the centrifugal force and sravity to expend themselves to the hest advantage in producing, the separation, as well as to make the machine simple, compact and easily kept in order. Fig. No. 1 is a perspective view of the Concentrator while in operation, showing tbe general arrangement. Vig. No. 2 is a section through the centre of the pan, showing how it operates in separating the sulphurets, as well as the great improvement to the pan, which consists of the addition of a circular trough outside the periphery. Its operation is as follows: The pulp flows from the’ spout through the filler into the bow] at the top, from which it is distributed equally over the convex cover into the pan near its outer edge. The lightest sand is at once carried off with tlie overflowing water through the centre opening, and the sulphurets are allowed, from the motion given to the machine, to gravitate to the bottom toward the outer edge, forming an embankment all around the pan, as represented at J, 1, Fig. 2. The lighter particles of the sand arranging themselves on the top, at 2, 2, Fig. 2, from which they are heing constantly washed away with the water flowing through the central opening. The sulphurets are, hy the centrifugal motion of the machine, made to pass through small openings at the hottom, at intervals of a few inches around the circumference, through the inner wall of the pan to the circular trough 3, 3, Fig. 2, where they come iu contact with the mercury at the bottom, Quicksilver, Ete. depositing the free metal, from which it is drawn at pleasure by an opening iu the hottom, and the sulphurets, in the order of their density, hy openings in the sides. it will he observed tbat the sulphurets in the trough, 3, 3, are maintained at the same elevation as the sulphurets and overlying sand in the body of the pan. It will he further observed, that by no possible means can the sand in the latter pass to the former in such quantities as to form any considerable percentage of the amount saved. The advantages of this improved pan are continuous action, requiring no attention except to remove the receiving vessels as fast as tbey are filled from the openings shown on the right of Fig. 2, simplicity in construction, and durability and cheapness of cost. The pan derives its motion from two eccentrics secured on a horizontal shaft passing across and below the centre of the pan and working between two pair of adjustable wooden guide hlocks or hearings. The eccentrics are so made as to hear equally on the wooden guide hlocks in all positions while in motion; giving to the pan the most desirahle motion for its purpose, and doing away with all complexity of rods, cranks, wooden frame, ete. Recommendations. 5 “Tell Mr. Hungerford that his machine is worth its weight in gold. I have proved, by actual test, that it will pay for itself every five days, running on the Vulture rock. I found that it yielded nearly $1,000, out of 120 tons, and then it was forced beyond its actual capacity. There is no douht about its utility, and every quartz mill operator in this section, and all other quartz-mining localities, will find them an absolute necessity. J. TYSON, “Dated Wickenhurg, Cal., January 2, 1866.” “Sonora, September 24, 1864, “ We have been using one of Prater’s Concentrators, at our mill, with the most signal success, for some months past. The yield of the rock at our mill is about $45 per ton, while rock from the same ledge crushed at other mills not using this Concentrator, is yielding hut $25. The sands from the batteries in our mill are received from tbe stamps direct into the Concentrator, which effectually separates all the gold, amalgam, and sulphurets from the rock, with the above results. : “WHEELER & THAYER.” It should be horne in mind that Mr. Hungerford is the original builder and maker of the celehrated Prater Concentrator, and his name should he sufficient guarantee to warrant the public in examining his new machine before purchasing elsewhere. _: Those interested in mining, and who call at the Miners’ Foundry to see the one which is there D> in operation, will have no reason to regret their visit.
