Effective methods of chalcedonite processing

Chalcedonite is an unique mineral with high variability in its density, which may cause problems in its industrial utilization. This study was aimed to find more effective methods for chalcedonite processing based on density separation. The method presented in the paper has been patented, and the results from this study showed that separation product were of a higher quality. Products of density separation have also lower variations in their density values what may results in their more effective industrial utilization.
