The present disclosure relates to a metal recovery process comprising a solvent extraction process. In an exemplary embodiment, the solution extraction system comprises a plant with a first and second circuit. A high-grade pregnant leach solution ('HGPLS') is provided to the first and second circuit, and a low-grade pregnant leach solution (“LGPLS”) is provided to the second circuit. The first circuit produces a rich electrolyte, which can be forwarded to a primary metal recovery, and a low-grade raffinate, which can be forwarded to a secondary metal recovery process. The second circuit produces a rich electrolyte, which can also be forwarded to the primary metal recovery process. The first and second circuits are in fluid communication with each other.

A cargo and storage rack for increasing the carrying capacity of a vehicle having a spare tire mount on the exterior of the vehicle. Retaining features of a mounting boss engage the retainment features of the spare tire to the spare tire mount. The mounting boss is adapted to receive storage brackets above or below or both of above and below the mounting boss, to secure cargo securing features at desired distances of engagement from the boss. Rails of any bracket secured to the boss provide support for alternately translating and selectably locatable cargo supporting features, such that the rack can secure cargo without a bracket that provides its own securing features. Optionally, the rack can support cargo with any combination of selectably locatable cargo supporting features on the rails and a bracket, and the rack comprises methods of construction and customization that facilitate rapid reconstruction of the rack and removal from the vehicle.

A process and system is provided for recovery of one or more metal values using solution extraction techniques and for metal value recovery. In an exemplary embodiment, the solution extraction system comprises a first solution extraction circuit and a second solution extraction circuit. A first metal-bearing solution is provided to the first and second circuit, and a second metal-bearing solution is provided to the first circuit. The first circuit produces a first rich electrolyte solution, which can be forwarded to primary metal value recovery, and a low-grade raffinate, which is forwarded to secondary metal value recovery. The second circuit produces a second rich electrolyte solution, which is also forwarded to primary metal value recovery. The first and second solution extraction circuits have independent organic phases and each circuit can operate independently of the other circuit.

System and method for parallel solution extraction of one or more metal values from metal-bearing materials

The present disclosure relates to a process and system for recovery of one or more metal values using solution extraction techniques and to a system for metal value recovery. In an exemplary embodiment, the solution extraction system comprises a first solution extraction circuit and a second solution extraction circuit. A first metal-bearing solution is provided to the first and second circuit, and a second metal-bearing solution is provided to the first circuit. The first circuit produces a first rich electrolyte solution, which can be forwarded to primary metal value recovery, and a low-grade raffinate, which is forwarded to secondary metal value recovery. The second circuit produces a second rich electrolyte solution, which is also forwarded to primary metal value recovery. The first and second solution extraction circuits have independent organic phases and each circuit can operate independently of the other circuit.

The present invention relates to a method and article for manipulating an amount of organic material entrained in an aqueous phase of a solvent extraction process. The method includes estimating an interfacial shear stress between an aqueous phase and an organic phase of a solvent extraction apparatus, estimating an amount of organic material entrained in the aqueous phase based on the estimated interfacial shear stress, and manipulating one or more solvent extraction process parameters to manipulate the amount of organic material entrained in the aqueous phase. The method and apparatus can be used to improve performance of and reduce operating costs associated with the solvent extraction apparatus.
