Exploitation of clay from el-maghara coal washing in land reclamation [electronic resource].

Includes references.

Treatment of wastes can be helpful for different fields such as environment, industry and cultivation. The treatment of wastes of El-Maghara coal washing plant by flotation was done in a previous work in order to recover the fine coal from the filter cake. A c.onsiderable amount of clay was produced at the end of flotation process. The main objective of this work is to use the resulted clay as a mud layer for sandy lands in Sinai to improve it and to make it suitable for cultivation of some strategical crops. Ditfferent types of soil, namely, filter cake soil (without treatment), the residual clay (the tailing produced after the treatment of the filter cake by flotation) and Nile valley soil were investigated and compared. In this regard, wheat was selected and investigated in such soils, It was found that the reclamation of sandy lands is possible by mixing the surface layer of sand bed with the clay produced from the waste of El-Maghara coal washing plant.
