Beryllium and some beryllium compounds are toxic and must be handled carefully Workplace-related exposures to dusts or fumes of beryllium and beryllium compounds are known to cause serious health problems such as cancer or chronic beryllium disease which is an immune system response that can damage the lungs

The extraction and the recovery of beryllium substantially devoid of zinc and other impurities from low and medium grade acid-leachable berllium bearing ores e g bertrandite is accomplished by acid leaching at a pH below about 2 but above about 1 2 preferably between 1 3 and 1 5 and advantageously with the aid of a soluble fluoride additive to recover the beryllium in solution with

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 gas solid 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
