Record 1 2005-01-07

English

Subject field(s)
  • Geochemistry
  • Erosion and Weathering (Geol.)
CONT

Oxidization of porphyry deposits can ... reduce sulphide contents of gold zones, thus improving extraction of gold by heap-leach methods.

CONT

Subsequent weathering has markedly changed the appearance and mineralogy of much of the carbonaceous Carlin-type ore through bleaching and oxidation.

French

Domaine(s)
  • Géochimie
  • Érosion et corrosion (Géologie)
CONT

L'oxydation des gîtes porphyriques peut [...] entraîner une réduction de la quantité de sulfures des zones aurifères, facilitant ainsi l'extraction de l'or au moyen de méthodes par lixiviation en tas.

CONT

Une météorisation subséquente a beaucoup affecté l'apparence et la minéralogie d'une large part du minerai carboné de type Carlin par blanchiment et oxydation.

Record 2 2004-01-07

English

Subject field(s)
  • Chemical Engineering
DEF

Chemical reaction of a compound with oxygen or a reaction that causes an atom or a group of atoms to lose one or more electrons.

OBS

The term "oxidation" originally meant a reaction in which oxygen combines chemically with another substance, but its usage has long been broadened to include any reaction in which electrons are transferred. Oxidation and reduction always occur simultaneously (redox reactions), and the substance which gains electrons is termed the oxidizing agent.

OBS

The opposite of reduction.

French

Domaine(s)
  • Génie chimique
DEF

Réaction au cours de laquelle un composé chimique (dit «réducteur») perd des électrons au profit d'un autre (appelé «oxydant»).

CONT

Il ne peut y avoir oxydation d'un composé sans qu'il y ait réduction simultanée d'un autre composé.

OBS

Contraire de réduction.

Spanish

Campo(s) temático(s)
  • Ingenieria química
DEF

Originalmente era la reacción en la que el oxígeno se combina químicamente con otra sustancia. Su uso ha sido muy ampliado e incluye cualquier reacción con transferencia de electrones.
