Beneficiation of Denizli-Acigol sodium sulphate ore by exploiting its structural properties.

Acigol Lake is currently the leading source of natural sodium sulphate in Turkey; it is produced from brines underlying a large playa. Large production reservoirs are formed on the lake by barriers and production is carried out in six steps: pumping, evaporation, crystallisation on cooling, drainage, dehydration and winning of the evaporate. Because the natural and climatic conditions around the lake are used in the production process there are many impurities, including stones and soil. Autogenous grinding and gravity concentration (jigging) and classification were investigated to remove these impurities. As a result of the investigations a gravity concentrator for preconcentrating Glauber's salt has been designed by Dedegil and is in use at the production plant.
