through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. this is a type of gravity separation. magnetite concentration methodsthe objectionable elements occurring with magnetite which are wholely or partially eliminated by magnetic concentration, are, in the order of their importance, phosphorus as apatite, sulphur as pyrite, etc., and titanium as menaccanite or ilmenite. apatite (calcium phosphate, sp. gr. 3.18 to 3.25) is usually feebly magnetic, though not sufficiently so to be picked up by magnetic fields of low intensitya red variety, found at mineville, n. y., is sufficiently magnetic to be sometimes drawn into the heads by the ballnorton separator. this mineral is a common accessory in magnetite oresit is quite brittle, and, on being crushed, forms a fine powder which has a tendency to stick to the magnetite grains and so find its way into the concentrate. this tendency is less marked when the concentration is carried out in water, and may be quite thoroughly overcome by the use of a spray of wash water while the magnetite is held by the magnets. in dry concentration the use of a blast of

abundant at moisie, on the st. lawrence, and in smaller developments in the united states at block island, on long island, along the great lakes and on the pacific coastabroad, deposits in brazil and new zealand have attracted attention. the writer is not informed of any present commercial operation on such depositsmagnetic impurities in the sands (menaccanite, etc.) and the unreliability of the deposits due to their mode of formation have probably been the chief causes of failure. see full list on 911metallurgist with ores which require fine comminution for the liberation of the magnetite the concentrate produced is usually briquetted, as fine concentrate is not acceptable at the furnaces. while the mill at edison, n. j., was in operation the ore was crushed to pass 1/16in. x ½ in. openings, and the concentrate briquetted. in sweden the briquetting of concentrate is usual. in sweden the plants installed by the grondal kjellin co. have been very successful. the fine concentrate is pressed into briquettes without the use of binding material, the moisture in the concentrate being regulated to obtain briquettes sufficiently firm to be removed from the press and loaded onto the cars used in the furnace. these cars are made of a frame covered with firebrick and have a tongue cast in the frame at the front end and a groove at the rear end, and along the sides are fitted with a flange which dips into a groove filled with sand in the furnace, a string of these cars thus forming an airtight platfor see full list on 911metallurgist certain ores of zinc and lead, corundum, etc., carry magnetite where this mineral is regarded as an objectionable impurity and from which it is eliminated by magnetic separation. at santa olalla, huelva, spain, the sociedad minas de cala is operating a magnetic separating plant on magnetite ores carrying chalcopyrite, and also experimenting on a mixture carrying the same minerals with hematite and silica. the ore is reduced by jaw crusher to 3 to 5 cm. and delivered by bucket elevator to hopper bins having capacity for 10 hours run. from these bins the ore is fed to a smidt ball mill by an eriksson automatic feeder, and reduced to pass 1 mm. this pulp is sent by launder to an eriksson magnetic separator. the results of the separation follow: the reseparation of the magnetite concentrates is made to remove the copper with its
