Title: A method for pressurised leaching of ore
Inventor: ACOSTA DE NOACK SONIA
Filed: 2016-06-19
Abstract: A method and a system for pressurised leaching of ore. The method comprises: heating ore slurry comprising ore and solvent, reacting and holding the heated ore slurry at working temperature for leaching valuable species into the heated solvent, and cooling the ore slurry. The pre-heating of the ore slurry in a pre-heating step is realized by thermal energy of a first heat transfer medium. Said ore slurry is further heated in a final-heating step to said working temperature by thermal energy of a second heat transfer medium separate from the first heat transfer me-dium. The reacted ore slurry is cooled in a cooling step by absorbing the thermal energy of the reacted ore slurry to the first heat transfer medium. Said first heat transfer medium is circulated between the cooling step and the pre-heating step. (Figure 1)

Title: Downhole flow diversion device with oscillation damper
Inventor: CRAMER DAVID S
Filed: 2017-08-22
Abstract: ABSTRACT A device for limiting the flow of drilling fluid through a section of drill string is described. The device includes a cylindrical tube with holes in its periphery. Flow enters the device through an upper end of the tube and a portion of the flow exits through the lower end of the tube. In addition, some of the flow is diverted through the peripheral holes. A valve piston is supported near the lower end of the tube by a spring of approximately constant force through its range of travel. The valve piston moves axially as the flow rate through the tube changes flow rate to ensure that a substantially constant amount of flow exits through the lower end, while the excess flow is diverted from the tube through the peripheral holes. A means of damping or stopping the axial movement of the valve piston is included in the device. See Fig. 1.
