Abstract
The potentiality of Escherichia coli dead biomass for biosorption of rare earth elements (REEs) and uranium (VI) from chloride leach liquor of laterite ore was evaluated. The effects of different acid, different concentration of hydrochloric acid, contact time, solid/liquid phase ratio and temperature on leaching efficiency of laterite ore were investigated.
Highlights
Laterite ore was found in southwestern Sinai, Egypt
Several leaching studies have been performed upon comparable Abu Zeneima ore from different locations, but with different constituents and grades of the economic metal values as U and other valuable elements [1,2]
Factors affecting the dissolution of valuable elements from laterite ore Effect of different acid on rare earth elements (REEs) and uranium dissolution: The influence of different kind of acid has significant effect on REEs and U(VI) was carried out using H2SO4, HNO3, HCl and HClO4
Summary
Laterite ore was found in southwestern Sinai, Egypt. It has been found to host several economic metal values. Several leaching studies have been performed upon comparable Abu Zeneima ore from different locations, but with different constituents and grades of the economic metal values as U and other valuable elements [1,2]. They concluded that both metal values could be almost completely leached by mineral acid under mild agitation or percolation leaching conditions. Lanthanides and uranium are strategic elements and essential for many applications. One of such application is as catalyst for petroleum cracking, phosphors in color television sets, as polishing powder, in flint stones, ignition device, super conductor, hydrogen storage, secondary battery, in optical lenses, in streetlights, searchlights. Uranium as a fuel in nuclear power plants and nuclear weapons [3]
