ABSTRACT
Denizli - Acigöl is one of the most important sodium sulphate source of Turkey. In Acigöl production field, natural parts of the lake are surrounded by barriers to form the production reservoirs. After the formation of these production reservoirs, the sodium sulphate production is carried out in 6 steps; these are pumping of water from lake to pond, evaporation, crystallisation due to cooling, drainage after crystallisation, dehydration and winning of the evaporate. The sodium sulphate production is performed due to natural and climatic conditions around the lake. Because of this, sodium sulphate crystals formed in production ponds are polluted by the impurity particles (stone, soil, plant wastes) coming from the environment of the lake. As these pollutant particles can not be dissolved in water and can not be eliminated by easy washing procedures they cause both inefficiency and production causalities in the following production steps. In this study, the applicability of separation of Denizli - Acigöl sodium sulphate ore by layered flow classifier technique was investigated. Beneficiation studies were carried out on samples which contained 4,22 % by weight refuse particles.
