Title: Process for producing metals
IPC: C21B13/00
Filed: 1942-02-05
Abstract: 573,539. Extracting iron and other metals. MINERALS & METALS CORPORATION. Feb. 5, 1942, No. 17431/43. Convention date, April 9, 1941. Divided out of 571,240. [Classes 72 and 82 (i)] In a process for reducing iron, copper, zinc, lead, tin and other metals from their ores, the ore, freed from gangue as completely as possible, and which may be mixed with a small percentage of carbon, is fed from a hopper 10 into pans 11 which pass under a bar 15 for levelling the charge, and then under a burner 16 which ignites the carbon in the top layer. The use of the burner is dispensed with when carbon is not employed. The pans then pass between hoods 17, 18 where heated air or combustion products or both, from a pipe 19, are passed through the charge which is thereby preheated and roasted at relatively low temperature to prevent excessive sintering. The hot ore then passes between hoods 23, 24, where hot reducing gases are passed from a pipe 25 through the charge to effect partial reduction. The partially reduced charge is dumped and falls downwardly, through the reducing gases, into a hopper furnace 30, through a passage 32 in which additional heat is supplied. The reduction of the ore is completed, during its fall, at a temperature higher than that at which the partial reduction is effected, but below that which would cause sintering and agglomerating of the ore particles. The hopper furnace 30 may be sealed at the bottom by compacting rolls 33, 34. The roasting step may be omitted, in which case preheating before reduction may be effected by combustion of solid fuel mixed with the ore or by .the heat of the reducing gases alone. An extension 31 of the hood 23 and a suction pipe 29 ensure the provision of a reducing atmosphere through which the. partially reduced ore falls to the furnace 30. In place of said furnace, a heating furnace of the batch or continuous type may be used, charged by a conveyer and dipscharged by a roller conveyer feeding the. hot material into .compacting rolls. Specification 557,868 is referred to.

Title: Benefication of ilmenite
Inventor: LO CHING LUNG
IPC: C22B34/12
Filed: 1965-04-27
Abstract: Acid-soluble non-titaniferous values present in ilmenite are removed by leaching the ore in two stages; the first stage is carried out with a mixture of second stage leach liquor and sufficient fresh HCl of at least 20 DEG  B<\>ae strength to provide about 60% of the stoichiomeric amount required for the dissolution of the acid-soluble values; the second stage is carried out with fresh HCl of at least 20 DEG  B<\>ae in an amount sufficient to provide about 150% of the stoichiometric amount required for dissolution of the remaining acid-soluble values.  The leaching liquid is maintained at at least 105 DEG  C. for the major part of the leaching time.  Preferably the total of acid values used in both stages does not exceed 120% of the stoichiometric amount required for the dissolution of the acid-soluble values in the ore.  The process may be carried out at at least 35 p.s.i.g. for at least the major part of the leaching time, e.g. 4-6 hours for each stage.  The fresh HCl may be commercial grade 20 DEG  B<\>ae acid.  The particle size of the ore may be essentially unchanged by the leaching. The leaching can remove Al, Mn, V and Fe values. FeCl2.4H2O and FeCl3.6H2O can be recovered from the leach liquor.

Abstract: 460,184. Knitting. HOSIERY DEVELOPMENTS, Ltd., JONES, T. H., and MILLS, R. K. July 20, 1935, Nos. 17709 and 27949. [Class 74 (ii)] In order to prevent striping or ring-effects due to inequalities or variations in the size and/or shade of the yarn, an anti-ladder fabric or article produced on a straight bar machine consists of a repeating series of courses in which two or more threads, functioning as ground thread or as stitch locking thread, or having both functions, are laid in successive courses of each series, and appear therein at the same face of the fabric. The locking of the stitch loops may be effected by completely encircling each leg of a stitch loop with locking thread, which also extends from one side to the other of the loop. In the fabric shown in Fig. 1, courses are knitted in sequence from "different" ground threads a, b, c, (i.e. threads of the same type, but drawn from different supplies), a fourth thread d being used as a stitch locking thread to form locking loops in each course. In a modification, Fig. 3 (not shown) a single ground thread k forms all courses, but three stitch locking threads l, m, n are used in order in successive courses. In another modification, Fig. 2 (not shown), three different ground threads e, f, g, are used in order in successive courses, these ground threads being associated respectively with three different locking threads, h, i, j. Fig. 4 shows a fabric in which threads o, p, operate in successive courses alternately as ground thread and locking thread. Fig. 5 (not shown) depicts a fabric in which four threads q, v, s, and t produce successive stitch courses, each thread being subsequently traversed in an opposite direction as a locking thread in the next but one succeeding course. In the construction shown in Fig. 6 three threads t, u, v, are employed in order in successive courses, each thread being first traversed as a ground thread to form a course of stitch loops, and then immediately returned as a locking thread for the same course. Where one or more threads function solely as locking threads these may be finer than the ground threads. The traverse of the locking thread may be interrupted as required. Specifications 329,098, [Class 74 (ii)], and 422,779 are referred to.
