Description

The process is based on such characteristic properties of boric acid and borates as: solubility depending on pH-value; and high ion-exchange resin capacity for borates and its regeneration by means of ammonia solution. On the basis of laboratory investigations a pilot plant BOR 100 was built 1993. The operation of the pilot plant started at the beginning of 1994. After the functional test and start up in the first half year 1994 the treatment of few batches of original evaporator concentrates was performed
