Record number: 2, Textual support number: 1 CONT
As the richer ores of gold (and other metals) are depleted, it is necessary for mining companies to focus on low-grade refractory gold-bearing ores in which the gold is encapsulated in the crystal structure of a sulphide matrix (typically pyrite). These ores cannot be broken down by cyanidation without an oxidative pre-treatment such as nitric acid oxidation, roasting, pressure oxidation or biological oxidation using microorganisms. 4, record 2, English, - pressure%20oxidation

Traitement en autoclave. La majeure partie du minerai de la propriété Goldstrike est «réfractaire» et contient de l'or enfermé dans des minéraux sulfurés. La présence de sulfure diminue l'efficacité de la lixiviation au cyanure et réduit considérablement la récupération d’or à partir de ces minerais. Pour améliorer la récupération, le minerai réfractaire est soumis à un traitement supplémentaire entre les circuits de broyage et de lixiviation, soit l'oxydation sous pression(«traitement en autoclave»), afin d’oxyder les minéraux sulfurés. Cette méthode améliore le taux de récupération d’or, qui passe d’environ 30 % avant l'oxydation à plus de 90 % après celle-ci. 1, record 2, French, - oxydation%20sous%20pression

In the case of most refractory ore concentrates, it is necessary to destroy the chemical bonds locking in the metals through some form of oxidation in order to achieve commercial metal extraction. Normally this liberation is achieved through either high temperature "roasting" of the ore, extremely high pressure oxidation, or other forms of treatment using bacteria (such as biological oxidation). 3, record 5, English, - high%2Dpressure%20oxidation
