Environment BeST BeST Beryllium Science

Beryllium-containing ore bodies, and consequently products manufactured from these ore-bodies, contain only the stable isotope, 9 Be. Particles produced from anthropogenic processes, i.e., the burning of coal, or the manufacture of products, are generally much too large and too heavy to move into the upper atmosphere.

Roasting (metallurgy) Wikipedia

Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gassolid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation
