An investigation into the fluorination capabilities of ammonium acid fluoride under microwave radiation with respect to zircon
… inertness. Extreme processing conditions such as alkaline fusion (NaOH at 600 °C or Na2CO3 at 1200 °C) are used to extract the zirconium values from the mineral. The purpose of this study was to investigate the use of microwave digestion as an alternative process, and to determine the parameters …

Synthesis of zeolites from geological materials and industrial wastes for potential application in environmental problems
… activated by two different routes: (1) classic alkaline hydrothermal synthesis and (2) alkaline fusion prior to hydrothermal synthesis. In the first method, the synthesis of zeolitic materials was carried out generally in alkaline media, although KAO or its calcination product, metakaolinite …

The purification of industrial wastewater to remove heavy metals and investigation into the use of zeolite as a remediation tool
… conventional hydrothermal synthesis and second, alkaline fusion prior to hydrothermal synthesis. The results from both routes show that zeolite A was synthesised successfully. Finally, the experiments show that both natural and synthetic zeolites can be available in commercial quantities. …
