“…For limestone rock samples wherc the majör element is Ca (conduetivity 0.281 X 10^6 Siemens), the presence of Al (more condictive than Ca) in lıigiı concentrations markedly inereases the conduetivity. This is also noticed by Ashry et al, 1989 in the analysis of the electrical properties of some beaclı black sands. Meanwhile, the decrease of conduetivity is associated with the presence of K, Fe, Si, and Ti.…”

The mechanİcal, physical and electrical properties in addition to the chemical constitution have been measured for some samples of the most common roeks; granite and limestone. Besides, factor analysis was applİed giving rise to four specific factors controlling the mechanİcal behaviors of each rock type. In granite; the two most common factors measure the degree of rock compactness in terms of density, porosity and chemical constitution (Fe, Ca, K and Cr) and correlate the relation between mechanİcal, electrical and chemical constitution. Also, the limestone rock exhibits two most common factors. The first one measures the electrical properties in terms of porosity and other chemical elements such as: Ti and K, while the second factor measures the degree of silicification in terms of both Ca and Si.

“…Electrostatic separation plays the most important role in the final purification of monazite to realize high concentration of REEs [4]. It is based upon the differences in electrical properties of granular materials that are to be separated [5]. These differences can be found in dc electrical conductivity and dielectric parameters.…”

Electrical properties of rare earth elements (REEs) in some geological materials were characterized during the upgrading of monazite from Egyptian black sand. It has been found that there was a significant relationship between concentrations of REEs and dc conductivity. Also, dielectric constant, dielectric loss, polarization, relaxation time and resonance frequency of samples containing REEs, were measured at a frequency range up to 1 MHz. From these measurements, it has been found that the values of electrical conductivity, resonance frequency and dielectric polarization are inversely proportional to the concentration of REEs. For most relations, the correlation coefficients were found to be better than 99%.
