Abstract:
The main part of chrome ore reserves in Albania is represented by chrome ores with a low Cr2O3 content, mainly below 12%. There are currently 16 chromium enrichment plants operating in Albania, which process raw chromium ores with content ranging from 5% to 12% and rarely up to 20% Cr2O3.
The very low content of Cr2O3 in the raw material of these plants has increased the production cost of chrome concentrates, doing necessary the testing efforts to improve the technological-economic indicators.
This paper aims to show the results of the tests and analyses that were done in some of the plants and the results that were achieved through the measures taken to increase the concentrate grade, to reduce losses and to reduce the production cost of chrome concentrates. The method followed has been that of taking samples in the industrial process and analyzing them, thus finding opportunities where to intervene in the process to improve the technical-economic indicators.
Based in the testing and analyses it has been implemented the removal of significant amounts of waste before the grinding process or before the enrichment processes, through pre-concentration processes, which has reduced the cost of processing per ton of raw material. Also, it was concluded that the separation and enrichment of very fine particles in the equipment with suitable parameters for the treatment of fine particles improves the recovery, reducing the losses of Cr2O3 in the tailings.
