L\u2019or est surement le m\u00e9tal pr\u00e9cieux le plus connu et convoit\u00e9 au monde. Malgr\u00e9 cela il est tout \u00e0 fait possible de le recycler presque int\u00e9gralement. Cela permet simplement de le remettre dans l\u2019\u00e9conomie de mani\u00e8re \u00e9cologique. Est-ce n\u00e9cessaire, peut-on tout recycler ? Voici des pistes qui vont nous permettre d\u2019y r\u00e9pondre.<\/p>\n\n\n\n

Pourquoi recycler l\u2019or ?<\/h2>\n\n\n\n

Le premier argument pour encourager le recyclage est bien sur \u00e9conomique. Avec un gramme d\u2019or pur \u00e0 pr\u00e8s de 60\u20ac<\/a>, r\u00e9cup\u00e9rer ne serait-ce que quelques grammes deviennent vite tr\u00e8s int\u00e9ressant. Cela s\u2019explique par son r\u00f4le de valeur refuge mais aussi par la rar\u00e9faction de l\u2019or extrait des mines. En plus de cela, la demande sur ce m\u00e9tal n\u2019a jamais \u00e9t\u00e9 aussi importante. L\u2019or est donc un m\u00e9tal pr\u00e9cieux qu\u2019il est judicieux de recycler et de conserver le plus longtemps possible.<\/p>\n\n\n\n

Le second argument est bien entendu \u00e9cologique. Le rapport r\u00e9cent du GIEC<\/a> ne cesse de nous le confirmer : le monde va mal. Les ressources naturelles s\u2019\u00e9puisent et on ne peut d\u00e9sormais plus nier l\u2019impact de la pollution humaine sur les changements climatiques. Sans le recyclage seul l\u2019extraction permettrait de s\u2019approvisionner en or. Cependant l\u2019extraction a des cons\u00e9quences \u00e9cologiques d\u00e9sastreuses.<\/p>\n\n\n\n

Ass\u00e8chement des sols :<\/strong> Il faut des quantit\u00e9s d\u2019eau tr\u00e8s importantes pour distinguer l\u2019or des autres mati\u00e8res extraits des mines<\/p>\n\n\n\n

Pollution de l\u2019air :<\/strong> les machines utilis\u00e9es pour extraire, trier, transporter ou affiner l\u2019or sont extr\u00eamement gourmandes et utilisent des \u00e9nergies fossiles donc non-renouvelable.<\/p>\n\n\n\n

Contamination des eaux :<\/strong> mercure, cyanure, oxyde de soufre sont autant de d\u00e9chets issus de l\u2019extraction des m\u00e9taux pr\u00e9cieux. Tout cela sans compter l\u2019orpaillage ill\u00e9gal qui encourage la d\u00e9forestation, la pollution des rivi\u00e8res et l\u2019augmentation de conflits autour de ce trafic ill\u00e9gal.<\/p>\n\n\n\n

Ou peut-on trouver de l\u2019or \u00e0 recycler ?<\/h2>\n\n\n\n

Le luxe et la joaillerie :<\/strong> C\u2019est l\u2019utilisation principal de ce m\u00e9tal. L\u2019or a toujours fascin\u00e9 par son aspect et ses caract\u00e9ristiques et continue de nos jours. Du pendentif achet\u00e9 en en grande surface ou du bijou de grande maison d\u2019horlogerie chaque gramme d\u2019or compte. Chez Or Expertise vous pouvez vendre vos bijoux imm\u00e9diatement par rapport au cours du jour. Prenez rendez-vous ici pour une estimation gratuite et imm\u00e9diate.<\/p>\n\n\n\n

L\u2019\u00e9lectronique :<\/strong> Parce que les produits (smartphones, tablettes, ordinateurs) de l\u2019industrie \u00e9lectronique pr\u00e9sentent un cycle de vie tr\u00e8s court, ce secteur est un v\u00e9ritable gouffre pour la consommation d\u2019or. En outre, il est rare que les utilisateurs proc\u00e8dent \u00e0 la r\u00e9paration de leur mat\u00e9riel.<\/p>\n\n\n\n

La sant\u00e9 :<\/strong> couronnes dentaires.<\/p>\n\n\n\n

Bon \u00e0 savoir :<\/strong> Avec une tonne de composants \u00e9lectroniques d\u2019ordinateurs, on peut pr\u00e9lever jusqu\u2019\u00e0 230 grammes d\u2019or !<\/p>\n\n\n\n

Comment l\u2019or est-il recycl\u00e9 ?<\/h2>\n\n\n\n

Le recyclage de l\u2019or se d\u00e9roule en cinq \u00e9tapes principales :<\/p>\n\n\n\n

R\u00e9colte :<\/strong> on pr\u00e9l\u00e8ve les objets compos\u00e9s d\u2019or d\u00e8s le 9carats. Chaque objet ou pi\u00e8ce est analys\u00e9 et pes\u00e9 devant le client.
Tri :<\/strong> l\u2019or est envoy\u00e9 dans un laboratoire d\u2019analyse. Il est ensuite tri\u00e9 par niveaux de puret\u00e9 (c\u2019est \u00e0 dire en fonction du nombre de carats par objet).
Fonte <\/strong>: l\u2019or est fondu \u00e0 une temp\u00e9rature d\u2019environ 1100\u00b0C. En effet, le point de fusion du m\u00e9tal jaune (passage de l\u2019\u00e9tat solide \u00e0 l\u2019\u00e9tat liquide) se situe pr\u00e9cis\u00e9ment \u00e0 1064,18\u00b0C. On r\u00e9cup\u00e8re ainsi l\u2019or sous sa forme brute.
Affinage :<\/strong> l\u2019or est ensuite extrait et s\u00e9par\u00e9 des autres m\u00e9taux auxquels il pouvait jusqu\u2019\u00e0 pr\u00e9sent \u00eatre m\u00e9lang\u00e9 (alliage d\u2019or et d\u2019argent la plupart du temps). On obtient ainsi un or pur \u00e0 99,9%, soit 24 carats.
Reconditionnement :<\/strong> l\u2019or pur est enfin moul\u00e9 sous la forme de lingots d\u2019or ou de pi\u00e8ces d\u2019or<\/a> afin d\u2019\u00eatre r\u00e9introduit sur les march\u00e9s. Vous pouvez alors acheter ce type de produits directement dans notre soci\u00e9t\u00e9 en prenant rendez-vous dans l\u2019une de nos agences.<\/p>\n","protected":false},"excerpt":{"rendered":"
