Title (EN) SYSTEMS AND METHODS FOR IMPROVEMENT OF METAL RECOVERY AND STABILITY OF PILES
(FR) SYSTÈMES ET PROCÉDÉS D'AMÉLIORATION DE LA RÉCUPÉRATION DU MÉTAL ET DE LA STABILITÉ DES PILES
Abstract:
(EN) In embodiments, pressurized fluid containing reagents of formulated -mixtures of solids, liquids and gasses are delivered into a cased well then into the heap or pile to open or stimulate, new horizontal and vertical fluid pathways, channels, plus drains from the open bottom of the well to the bottom of the heap or pile for fluid collection. This delivery method may also drain any fluids that are retained and pooled in the heap or pile. The removal of pooled fluids will increase the inter-particle cohesion and friction in the heap or pile, thus adding geotechnical stability and resistance to movement of the heap or pile. The eased wells may also add-shear strength to the collective to retard movement of the heap or pile.
(FR) Selon des modes de réalisation de la présente invention, un fluide sous pression contenant des réactifs de mélanges formulés de solides, de liquides et de gaz est distribué dans un puits tubé puis dans le tas ou la pile pour ouvrir ou stimuler de nouvelles voies, canaux et drains de fluide horizontaux et verticaux, du fond ouvert du puits jusqu'au fond du tas ou de la pile en vue d'une collecte de fluide. Ledit procédé de distribution peut également drainer des fluides retenus et groupés dans le tas ou la pile. L'élimination de fluides groupés augmentera la cohésion et le frottement interparticulaires dans le tas ou la pile, ajoutant ainsi une stabilité géotechnique et une résistance au mouvement du tas ou de la pile. Les puits soulagés peuvent également ajouter une résistance au cisaillement au collectif pour retarder le mouvement du tas ou de la pile.
