Process for the extraction of alumina and phosphorus salts from aluminum phosphate ore |
| abstract |
Alumina and phosphorus salts are produced from Al phosphate ores by extraction with KOH soln. contg. 200-550 g/l. KOH with a calcd. caustic modulus of 2.3-8 at 80-60 min. The conditions depend on the composition of the ore. The extraction mixture is separated into a solid and a liquid phase. The washed solid phase is re-stored before the leaching process of an ambient temperature sufficient to ease the strains without degrading the resin. The product is used as upper in men's shoes and has a high coefficient of water vapour transmission. |
