Modern heap leach pads are large engineered structures, lined with an impermeable layer of plastic(referred to as a geosynthetic membrane) and placed over a prepared surface that is typically a compacted soil layer. Ore is placed(heaped) on the lined pad and treated with chemicals to dissolve(leach) a metal of interest while protecting the environment. The plastic liner placed at the bottom and around the sides of the pad prevents chemicals from leaking into the soil and contaminating groundwater. The plastic utilized for these liners must be capable of withstanding the excessive weight of stacked ore, the continuous application of corrosive chemicals, and harsh weather conditions over the long term. 3, record 1, English, - heap%20leach%20pad

Un aspect important, dans un contexte de risques, de nombreuses mines métalliques, a trait à l'extraction de métal sur des aires de lixiviation en tas. Cette technique est utilisée pour l'extraction dans le cas de l'or, du cuivre, de l'argent, de l'uranium, du nickel ainsi que de plusieurs autres métaux et métalloïdes [...] Une aire de lixiviation en tas consiste de manière schématique en une barrière composite [...] sur laquelle est placé le minerai destiné à être lixivié à l'aide, soit d'un acide fort (de l'acide sulfurique dans le cas du cuivre et du nickel), ou alors d'une solution diluée de cyanure (cas de l'or et de l'argent). 3, record 1, French, - aire%20de%20lixiviation%20en%20tas

Plasma surface treatment is extremely versatile and used in a range of industries. It can enhance biocompatibility, prevent moisture absorption through hydrophobic treatments, and it improves functionalization and adhesion-all from a value-driven, green alternative to harsh chemical techniques. It even extends treatment lifetime from days to years. 2, record 2, English, - plasma%20surface%20treatment

Traitement de surface par plasma - Dans l'industrie, on fait appel aux traitements plasma pour l'amélioration et le contrôle fin des propriétés de surface des matériaux : revêtement, nettoyage, activation, gravure... Lorsqu'une pièce est au contact d'un plasma, un film se forme à sa surface. Les molécules présentes dans la phase gazeuse conditionnent la nature du film formé. Les procédés plasmas sont des hautes technologies industrielles qui permettent le traitement de surface à haute performance et à haute valeur ajoutée de tous types de matériaux : métaux, plastiques et élastomères, verres, céramiques, composites, textiles, etc. 2, record 2, French, - traitement%20de%20surface%20par%20plasma
