It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. Rubidium is the first alkali metal in the group to have a density higher than water. On Earth, natural rubidium comprises two isotopes: 72% is a stable isotope 85Rb, and 28% is slightly radioactive 87Rb, with a half-life of 48.8 billion years—more than three times as long as the

Migration behavior of potassium and rubidium in compacted

Therefore the authors have carried out electromigration experiments of potassium or rubidium with source of iron ions supplied by anode corrosion of iron coupon in compacted bentonite. Five to fifteen micro liter of tracer solution containing 3.3 M of KCl or 2.2 M of RbCl was spiked on the interface between an iron coupon and bentonite, which dry density was around 1.4 Mg/m 3 ,

Extracting rubidium and potassium from complex rubidium ore:

2023年8月8日  This paper introduces a new method for efficiently extracting Rb and K from complex rubidium ore. It mainly consists of two steps: 1) thermal activating of rubidium ore and water quenching, and 2) leaching with sulfuric acid. After thermal activating and water quenching, the water quenched slag was in a highly active state. Efficient extraction of rubidium and
