properties and the knowledge acquired by development of extensive underground workings makes it possible to make quite definite estimates of tonnage available in certain areas, which show very large reserves. f. s. witherbee in his paper read before the american iron and steel institute last october gave an estimate of 1,100,000,000 tons of crude magnetic ore above 30 per cent. fe available for concentration in the adirondack region alone, not including any titaniferous ores except the one deposit at lake sanford. he practically confined his estimate to the area of the ironbearing gneisses which surround the central core of later eruptives, the anorthosites and gabbros, in which the titaniferous ores are found. there are also in new jersey and southeastern new york large areas that give conclusive evidence of vast amounts of nontitaniferous magnetites. the map accompanying the report of the state geologist of new jersey, 1910, sh see full list on 911metallurgist some time in the, 1887 my attention was called to the magnetic separation of ores. at that time edison was experimenting with his deflecting magnet and the wenstrom, a swedish machine of the drum type, was in use. the conkling machine, which was also on the market, was the forerunner of the modern belt machine, but the magnetic attraction came from a single magnetized plate. my first experiment was with port henry bed ore, which i crushed to pass through 1/8 in. mesh, and then ran through an fashioned fanningmill, such as are used on farms. i had better results than those obtained by mr. edison with his deflecting magnet. i then made a trial of the conkling idea but found that the magnetic plate picked up a large part of the gangue with the ore, so that the ore had to be sized and fed very slowly to get good results. the same trouble was experienced with the wenstrom machine. i then made a small machine, substituting common horseshoe magnets , for the magnetic plate of see full list on 911metallurgist the magnetic iron ores found in different localities vary widely, not only in their iron content, but also in their physical structure. the ores from the various districts require, consequently, radically different treatment. in the first place, bodies of ore differ widely in crystallography. for example, the ores of the champlain valley are more coarsely crystalline than the ores of new jersey, the benson mine, or the cornwall ore bed. obviously the mill treatment of these ores cannot be the same. among other things, ore containing the coarser crystals would not require to be crushed to so fine a size as ore of the cornwall type. it is very important to find the exact size at which any particular ore is most economically separated, and this size can easily be determined by experimental tests in a suitable laboratory. moreover, the degree of fineness to which the ore must be crushed determines the process of separation to be employed. an ore which must be crushed to 1/8 in., 1/16 in see full list on 911metallurgist the largest development in the ironore industry, using magnetic concentration, is at the plants of witherbee, sherman co. at mineville, n. y., where about 1,200,000 tons of crude ore were mined and separated in 1916. the dry process of separation is used. the chateangayore iron co., at lyon mountain, n. y., the empire steel iron co. and the ringwood co. in new jersey, also use the dry process successfully. the grondal wet separators have been recently installed at the benson mines in new york. the largest development of the, wet process in this country is on the cornwall ore at lebanon, pa. this work is in charge of b. e. mckechnie, who is the highest authority on the wet process. in the practical application of magnetic separation the most vital part is the preparation of the ore. it must be crushed so that the crystals of magnetite, or groups of crystals, are sufficiently freed from rock to bring the percentage of iron up to the standard set for shipping ore. on the other see full list on 911metallurgist during the dry magnetic separating tests on cornwall ore, it became evident that this process of magnetic separation was not suitable for this ore, for the following reasons: see full list on 911metallurgist the following reports show results of samples tested to determine treatment required and quality of concentrates that could be expected. these tests were run on a regular mill size separator and the results could be duplicated in actual practice. the separate determinations of iron as magnetite, and total iron, were made so that the difference between the two would show the amount of iron combined as silicates in hornblende and other gangue minerals. see full list on 911metallurgist the known and partially developed orebodies of new york and new jersey could, if equipped with the best modern mining and milling machinery and using the best methods, produce at the present time 25,000 tons of 60 per cent, iron ore per day. this can be delivered for an average freight charge of 0.75 per ton from mill to tidewater. the operating cost of production should reach the dollar rock ideal of the lake superior copper region, and the cost of mining and milling 1 ton of crude ore should be about 1 for underground mining when handled in large quantities. the ratio of concentration would be 2 tons of crude per ton of concentrates for an average. there are reserves of magnetic ore sufficient to double the above production, and then last probably 100 s. see full list on 911metallurgist
a discussion of magnetic separation techniques for dry magnetic separators, including both drum and roll types, generally offer far more precise separations than wet magnetic separators. dry magnetic separation is more controllable since the separation medium is air rather than water. separating particles from one another is naturally easier without having to fight drag forces created by water. 646kb 83magnetic separator,wet magnetic separator,magnetic drum application of magnetic separator. magnetic separator is a continuous automatic iron removal magnetic separation equipment from dry power. it s inner adopts unique magnetic circuit design, it make the highperformance permanent magnet king ndfeb materials as the magnetic source, strong magnetic field, big attraction force, high iron removal rate, has the advantages of three maintenance, energy wet magnetic drum separator gistlowintensity separators are used to treat ferromagnetic materials and some highly paramagnetic minerals. minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3t) magnetic separators. for lowintensity drum separators used in the iron ore industry, the standard field, for a separator with ferrite a discussion of magnetic separation techniques for dry magnetic separators, including both drum and roll types, generally offer far more precise separations than wet magnetic separators. dry magnetic separation is more controllable since the separation medium is air rather than water. separating particles from one another is naturally easier without having to fight drag forces created by water. eriez wet drum separatorswet drums for concentration duty. wet drum magnetic separators are the most vital part of the upgrading process in magnetite concentration. the upgrading of primary magnetite is always accomplished with wet drum separators. mill feed is typically upgraded to 65+ percent magnetic iron using a series of wet drum magnetic separators. wet drum magnetic separator jxsc machineapplication of magnetic separation wet drum magnetic separation is suitable for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other materials with a particle size of 3mm or less. it is also used for iron removal of coal, nonmetallic minerals, building materials, etc. 1. simple structure 2. big capacity 3.
