This work presents research results on the utilisation of chromic waste in the production of sodium chromate (VI). The optimal parameters of the sodium chromate (VI) process which make it possible to select the best technological solution were determined. This allowed the values useful for a practical estimation of the process, such as mass balances, technological figures and especially the quantity of the produced chromic waste, to be determined. Research on the on-site recycling of the chromic waste from old chromic heaps resulted in working out of the dry enrichment method of the waste stream which was returned to the sodium chromate process. Satisfactory enrichment resulted in the separation of the fraction 63-200 mum, where the enrichment rate was 1.27 at a separation degree of 0.32. (C) 2002 Elsevier Science Ltd. All rights reserved.
