Nigeria is the highest consumer of aluminium in Africa but lacks bauxite deposits. The replacement of bauxite alumina with other alumina bearing resources (clays in particular) has been proposed. The present study investigated the thermal treatment required to activate Edda clay from southeastern Nigeria for optimal leaching of alumina. The clay is composed mainly of kaolinite and quartz

This paper examines the possibility of the use of some clays calcined from Nigeria as partial substitutes for clinker in the production of Limestone Calcined Clay Cement (LC³).
Bauxite deposits for production of alumina are lacking in Nigeria and there is an aluminium smelter plant in the country which requires alumina for its operation. Development of alternative alumina resource using clays that are abundant in the country is the focus of this paper. The thermal activation of Ibere clay from southeastern Nigeria for optimal leaching of alumina was investigated.

2021-2-12 This process is called calcination reaction. This is the process by which ionized clayey soil, at the doubled diffused layer phase, when mixed with moisture, reacts with calcium ions (Ca 2+) from the ionized compounds of the additives to form flocs and build strength-gain matrixes responsible for strengthening in expansive soils. Additive

The production process involves the calcination of eggshells, which contain calcium carbonate (CaCO. 3) to extract calcium oxide (CaO) which was used to produce calcium hydroxide (Ca(OH) 2) [15]. Calcium hydroxide was also synthesized directly from the eggshells without calcination. The Ca(OH) 2 . produced from both process route were then
