Dans les circuits CIP, CIL et de lixiviation en tas, la cin\u00e9tique d'adsorption d\u00e9termine le stock de charbon ; la r\u00e9sistance m\u00e9canique d\u00e9termine les pertes par attrition ; l'efficacit\u00e9 d'\u00e9lution d\u00e9termine la dur\u00e9e du cycle. Un charbon qui donne d\u2019excellents r\u00e9sultats en laboratoire mais qui se pulv\u00e9rise lors de l\u2019agitation de la pulpe entra\u00eene une perte d\u2019or avec les fines, un colmatage des tamis et une contamination de l\u2019\u00e9luat.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Le d\u00e9fi et l'approche PureStar<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Le d\u00e9fi principal :<\/strong>&nbsp;Optimiser le \" triangle des substances difficiles \u00e0 \u00e9luer \" du secteur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Il est difficile de concilier simultan\u00e9ment une forte charge en or, de faibles pertes par attrition et une \u00e9lution rapide. De nombreux charbons d\u00e9veloppent de l\"\" or difficile \u00e0 \u00e9luer \u00bb : des complexes auro-cyanur\u00e9s pi\u00e9g\u00e9s dans des pores trop profonds ou trop \u00e9troits qui r\u00e9sistent aux conditions de stripage standard, ce qui entra\u00eene une perte cach\u00e9e de stock. Alors que la teneur des minerais diminue \u00e0 l\u2019\u00e9chelle mondiale, chaque gramme d\u2019or non r\u00e9cup\u00e9r\u00e9 \u00e9rode directement la marge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Le charbon de coque de noix de coco de PureStar, destin\u00e9 \u00e0 la r\u00e9cup\u00e9ration de l'or, est con\u00e7u pour offrir une g\u00e9om\u00e9trie optimis\u00e9e des orifices de ses pores et une duret\u00e9 m\u00e9canique exceptionnelle. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Plut\u00f4t que de rechercher une profondeur maximale des micropores, nous concevons des canaux poreux qui acc\u00e9l\u00e8rent la diffusion du cyanure d'or dans la particule et permettent de le lib\u00e9rer efficacement lors de l'\u00e9lution. Cette philosophie du \" facile \u00e0 entrer, facile \u00e0 sortir \" optimise le rendement r\u00e9el de l'installation et minimise le renouvellement du charbon.
