reactive material: A chemical substance or mixture that will vigorously polymerize, decompose, condense, or become self-reactive due to shock, pressure, or temperature. Includes materials or mixtures that fall within any of these categories: explosive materials; organic peroxides; pressure-generating materials; water-reactive materials.  6, fiche 1, Anglais, - chemically%20reactive%20agent

(chemical) reactivity: The relative capacity of an atom, molecule, or radical to combine chemically with another atom, molecule, or radical. It expresses the ability of a material to undergo a chemical change. A chemical reaction may occur under conditions such as heating, burning, contact with other chemicals, or exposure to light. Undesirable effects such as pressure build-up, temperature increase or formation of other hazardous chemicals may result.  6, fiche 1, Anglais, - chemically%20reactive%20agent

Le cyanure est utilisé couramment dans l'industrie minière pour l'extraction de l'or. La cyanuration est l'un des procédés les plus simples et les plus courants utilisé pour extraire le métal précieux de sa gangue minérale [...]. Le procédé est basé sur la capacité du cyanure à former des combinés, des sels avec l'or. Le métal précieux présente en effet l'inconvénient d'être inoxydable. Il est peu attaqué par les agents réactifs chimiques, à l'exception notable du cyanure, avec lequel il se combine pour former des sels d'or.  2, fiche 1, Français, - agent%20chimique%20r%C3%A9actif
