Extraction of uranium and valuable elements from Abu Hamata poly-mineralized sedimentary rocks, Southwestern Sinai, Egypt.
Walid Mahmoud Abdellah;
Abstract
S i n ai Peninsula is considered as one of the most important
mineralized areas in Egypt. It contains various mineral deposits e.g. Mn,
Fe, Cu, S and C beside kaolin, glass sands, beach sands and limestone,
which are widely distributed along the Gulf of Suez especially at East
Abu Zeneima area.
A bu Hamata sandy claystone rocks of Um Bogma Formation of
southwestern Sinai are considered as one of the most promising
occurrences for U beside the associated economic metal values e.g. Ln,
V, Zn, Cu,…. etc. as well as B which is recorded for the first time in the
present work.
T he main target of the present work; is to study the processing of
this ore material to recover its content of U, Ln, B and V, which are
important for many technological and nuclear applications.
For this purpose, a technological representative sample from Abu
Hamata sandy claystone ore material was collected. The mineralogical
analysis of this sample revealed the presence of montmorillonite as the
main clay mineral (K,Ca)Al2SiO4 together with quartz (SiO2) and
hematite (Fe2O3). The secondary U mineral renardite Pb(UO2)2 (PO4)2.
9H2O was recorded for the first time in the studied area by the present
work. On the other hand, it is worthy to be mentioned herein that there is
no identified minerals for Ln, B and V which are probably adsorbed upon
the clay mineral, montmorillonite.
C omplete chemical analysis of the technological sample shows
that, it is mainly composed of SiO2 which represents the main constituent

(55.6 %) beside Al2O3 (12.70 %) and Fe2O3 (9.81 %). K2O and MgO
represent the much lesser constituents of the study ore material.
Moreover, the sample was found to contain trace amounts of CaO, TiO2,
P2O5 and Na2O. It is worthy to be mentioned herein that the high contents
of SiO2, Al2O3 together with loss of ignition (11.1 %) and K2O reflect
the sandy clay nature of the studied ore material. Also, the chemical
composition of the study ore material shows the presence of 0.183 % of
U, 0. 137 % of Ln, 0.11 % of B beside 0.175 % of V.
