Özet

In beneficiation of chromite ores using gravity methods, the basic approach is to obtain concentrates with coarse sizes as long as possible. While some type of ores respond to this approach, some type of the ores needs very fine grinding. On the other hand, ratio values have importance in determining the quality of the marketable product. In this study, beneficiation properties and ratio values of two different chromite ores taken from Albania were investigated. On the KJM coded sample, jig tests (-25+1 mm) and shaking table tests (-1 mm) were performed. The ratio of the concentrate was determined as nearly 2.5. Besides, the liberation of the other sample - coded as KM - was provided below 0.6 mm. The concentrates of this sample had ratios varying from 2.18 to 2.41, since finely disseminated magnetite particles existed in chromite particles. In addition, magnetic separation tests were conducted in order to reduce the iron content. According to the optimized test results, appropriate process flow-sheets were established for both of the chromite samples.
