A multi-position sleeve assembly for use in a wellbore, comprising a tubular housing defining an axial bore, a first sliding sleeve, and a second sliding sleeve. The housing has an inner and outer surface defining therebetween one or more first ports and one or more second ports spaced axially from the one or more first ports. The one or more second ports are configured for restricted fluid flow relative to the one or more first ports. The first and second sliding sleeves are located in the bore and coaxial to the housing and are actuable relative to the housing between a closed sleeve position, wherein the one or more first ports and the one or more second ports are obstructed, and an open sleeve position wherein, one or both of the one or more first ports and the one or more second ports are not obstructed.

Multi-position sleeve assembly, systems, and methods for use in a wellbore

Method and apparatus are provided to select target metal particles from aggregate ore. A feed stream of aggregate is directed along a path and a higher density portion is segregated therefrom. Detectors are arranged in-line and along the flow of the higher density portion. High resolution detection of a target particles within the feed stream triggers ejection of a select portion of the feed stream and target particle as a concentrate and the balance continues to a further phase of detection/ejection. The concentrate is processed in further stages or collected as product. Multiple parallel detector/ejectors across the path can isolate target particles and minimize the ejected gangue portion associated therewith. Dry or hydrodynamic transport of the feed stream is available determined by aggregate characteristics. A compact footprint of the apparatus is achieved with arcuate paths and multi-level conveyance whilst low energy requirements enables use in artisan installations.
