[Dans] la méthode de radioéchappement (radiorelease method : RR) [...] La substance à analyser est mise en contact avec un réactif radioactif dont une partie de la radioactivité est libérée au cours de l'interaction. Cette libération peut avoir lieu lors d'un échange entre un solide et un liquide ou un gaz, ou encore entre un liquide et un gaz. Une des caractéristiques du radioéchappement est qu'une partie du réactif radioactif quitte la phase solide ou liquide sans être remplacée par une substance inactive. Si l'interaction est stœchiométrique, il est possible de déterminer directement la concentration à mesurer de la radioactivité libérée, sinon il faut avoir recours à une courbe d'étalonnage. 1, record 1, French, - m%C3%A9thode%20de%20radio%C3%A9chappement

Soluble sulphides are often used as activators in the conditioning of oxidised sulphide surfaces. They can also act as depressants if added in excess.... The metal-sulphide layer at the oxidised mineral surface, so long as it can be sustained, is available for the attraction of xanthate and flotation of the particle bearing this sulphidised surface.... The durability of the sulphidization by the added S [valence of negative 2] ions is determined by its depth, and therefore by the rate of diffusion into the surface during conditioning. 7, record 5, English, - sulphidization
