Metakaolin (Al 2 O 3 2SiO 2 ), a calcined product of kaolin with Si/Al ratio of 1 is a convenient starting material for the synthesis of zeolite A. This process is usually performed between 550 and 900 °C [8]. The synthesis of zeolite A from kaolin source started in the 1970s by the hydrothermal reaction of dehydroxylated kaolin with sodiumThe raw kaolin sample used in this study was supplied by Hawassa Ceramics Factory, located in southern part of Ethiopia; Commercial Zeolite 4A was purchased from Industrias Químicas del Ebro (Spain).Analytical grade NaOH pellets was purchased from Sigma Aldrich and 98% CaCl 2 6H 2 O from BDH.

Synthesis of zeolite A using low grade Bombowha kaolin from Ethiopia has been carried out by two methods: the conventional hydrothermal synthesis and alkali fusion followed by hydrothermal treatment. In the synthesis process, the metakaolinization was achieved by calcination of the kaolin at 600 °C for 3 h for the Conventional versus alkali fusion synthesis of zeolite

Kaolinite, a clay mineral, is an important industrial mineral which was gainfully utilized with several industrial significances. Towards mineral beneficiation, the present study aimed to investigate the effect of calcination temperature on the pozzolanic activity and specific surface area of Ethiopian kaolinite (Ek). The raw Ek and calcined Ek Since 2017 he has been involved in a research project in the area of Ethiopian kaolin characterization for different industrial applications as well as an indigenous microalgae investigation from wastewater for biodiesel production.

Kaolin (china clay) is a rock material that is very rich in kaolinite. A kaolin ore from Debre Tabor, Ethiopia containing 59.2 wt% SiO 2, 24.9 wt% Al 2 O 3, 2.4 wt% Fe 2 O 3, and 8.22 wt% loss on ignition (LOI) was physically beneficiated, chemically leached, and thermally treated for possible industrial use, especially for ceramic membrane The Mineral Industry of Ethiopia By Meralis plaza-toledo in 2019, the production of mineral commodities—notably gemstones, gold, pumice, and tantalum—represented only a minor part of the economy of ethiopia (BDo LLp, 2019, p. 35). the legislative framework for the mineral sector in ethiopia is provided by the Mining 2019 Minerals Yearbook USGS Publications Warehouse
