Rhenium Element information, properties and uses

The periodic table had two vacant slots below manganese and finding these missing elements, technetium and rhenium, proved difficult. Rhenium was the lower one and indeed it was the last stable, non-radioactive, naturally-occurring element to be discovered.

Rhenium an overview ScienceDirect Topics

Such elements are potassium, rubidium, samarium, lutetium, rhenium, and uranium. In these concentration measurements, the activity of the radioactive isotopes is measured. When the relative abundance of the radioactive isotopes is known, the quantity of the element that is present can be calculated from Eq.

Dilution versus bench height (Bozorgebrahimi et al., 2005). Figure 3. Large block of the simple sequencing method. In open pit mining, factors that can affect the degree of dilution can be regarded as deposit-related or mine-related. The bench height is a mine-related parameter that can be studied using a simple geometrical model of
