Fluorite on QuartzKara Oba Kazakhstan

Fluorite on QuartzKara Oba Kazakhstan

A beautiful example of octahedral fluorite on quartz, form the notable finds at KaraOba in the early 1990's. This piece has the sharp, dark purple octahedrons that are typical from the loion, though not often seen for sale. It seems I always see pictures of them in other people's collections, but they're never actually available.

Refinery HF Alkylation

Refinery HF Alkylation

Process Description. Olefins (C3C4) from the FCC unit are combined with isobutane (iC4) and are first treated with a mol sieve bed to remove water. Concentrated Hydrofluoric Acid (HF) is then mixed in and fed to the reactor. The alkylation reaction takes place combining the olefins with the isobutane to form the alkylate product which ...
