Strontium primarily occurs in mineral form as celestite and strontianite. You can obtain a source to isolate pure strontium by mining celestite. Chemical reactions between strontium oxide and aluminum produce pure strontium in the laboratory. Strontium metal can be prepared by electrolysis of strontium chloride mixed with potassium chloride.
Stream carbon fluxes are one of the major components in the global C cycle, yet the discrimination of the various sources of stream carbon remains to a large extent unclear and less is known about the biogeochemical transformations that accompany the transfer of C from soils to streams. Here, we used patterns in stream water and groundwater δ13C values in a small forested tropical headwater ...

(Strontium may remain in the bones for as long as 7–10 years after the last dose.) Strontium has a chemical similarity to calcium and will replace calcium as the mineral in bone. Because strontium atoms are heavier than calcium atoms, swapping some of the calcium atoms with strontium atoms will make the bone mineral density appear to increase.

The source attribution was realized with the help of graphic aids where net signatures, or else the relation of signatures, were obtained for the different elements detected (calcium, titanium, iron, manganese, rubidium, strontium, yttrium, zirconium and niobium). The X-rays were generated with a tungsten tube operating at 45 kV and 0.8 mA.

Strontium is accommodated in the lattice of this calcite as shown by the SEM image. The carbonate mineral is denominated as Sr-bearing calcite rather than strontium calcite which has an almost equal share of Sr and Ca in the lattice and has so far only been recorded from high-grade metamorphic and alkaline igneous rocks ( Boundy et al., 1997 ...
An iron-poor stream of nearly neutral pH polluted by mine tailings has been investigated for a natural phenomenon responsible for the polishing of heavy metals in mine wastewaters. A white mineralized mat, which was determined to be hydrozincite [Zn5(CO3)2(OH)6] by X-ray diffraction analysis, was observed in the stream sediments mainly in spring. The precipitate shows a total organic matter ...
