Title: Process for separating and recovering metals
Inventor: BHADURI RAHUL SHANKAR
IPC: B01J38/72
Filed: 2011-08-10
Abstract: A process for treating spent catalyst containing heavy metals, e.g., Group VIB metals and Group VIII metals is provided. In one embodiment after deoiling, the spent catalyst is treated with an ammonia leach solution under conditions sufficient to dissolve the group VIB metal and the Group VIII metal into the leaching solution, forming a leach slurry. After solid-liquid separation to recover a leach solution, chemical precipitation and solids repulping is carried out to obtain an effluent stream containing ammonium sulfate (Amsul), ammonium sulfamate, Group VB, Group VIB and Group VIII metals. Following sulfidation, the Group VIII metal is fully removed and Group VB and Group VI metals are partially removed from the Amsul stream. In the additional steps of oxydrolysis and iron precipitation, an effective amount of ferric ion at a pre-select pH is added to form insoluble complexes with the Group VB and Group VIB metals, which upon liquid-solid separation produces an effluent ammonium sulfate stream containing less than 10 ppm each of the Group VB and Group VIB metals.

Abstract: Acoustic tags have been used for years in fisheries research to study survival and behavior of fish in various aquatic environments. The described techniques, devices and systems enhance the ability of researchers to understand the effect on fish mortality by predators through an acoustic tag that includes a digestible fuse. When the implanted acoustic tag comes in contact with the digestive fluids in a predator's stomach, the fuse coating is dissolved causing the fuse to disintegrate and result in an open circuit. The open circuit in turn signals the electronics in the acoustic tag that the tagged fish has been consumed. In response, the electronics alter the tag transmit signal to indicate that predation has occurred.
