Abstract
<PICT:0812486/III/1> In the continuous leaching of boron ores, water or aqueous sodium carbonate solution flows continuously through a stationary bed of the coarsely disintegrated ore, preferably in an upward direction. The bed may be replenished either continuously or intermittently. It is convenient to adjust the flow of the leaching medium so that the fine residue is entrained and thus removed, whilst the coarse residue may be removed either intermittently or continuously. In the example (see the Figure) crushed colemanite ore is introduced from the top of a tube A and a leaching solution at about 80 DEG C., containing borax, sodium carbonate, and sodium bicarbonate, enters at the bottom. Fresh ore is continuously added at the top and any residue is removed intermittently from the bottom by a hand-operated screw conveyer. The slurry emerging at the top of A, above the level of the solids, enters a vessel B where sodium carbonate is added, and the solution is then filtered in C, the resulting solution and washings being transferred to D, where sodium borate is crystallized out, and separated in the centrifuge E. The mother liquor, at about 30 DEG C., passes to container F, where flue gas is passed through to raise the sodium bicarbonate content. The liquor is now passed through a heat exchanger in D and the heater G, and is recycled to A. The filtered residue is discharged at R, and the product at P. Carbon dioxide or carbon dioxide containing gases may be introduced into the leaching vessel from below, when the upper part of the vessel is cooled. The leaching vessel may be heated, preferably by introducing live steam. The process may be performed at or above atmospheric pressure.
