Title: Gold and silver electrorecovery from thiosulfate leaching solutions
Inventor: LAPIDUS LAVINE GRETCHEN TERRI
IPC: C25D3/46
Filed: 2011-12-09
Abstract: The present invention pertains to the mining industry and to the processing of minerals and materials containing gold and silver. More specifically, it relates to a method for recovering gold and silver from copper thiosulphate solutions by a self-sustaining electrolytic process. The advantages of the present invention over the prior art are that it is faster than cementation with copper, without using electric current. The claimed method is characterised in that it is performed in a self-sustaining electrochemical cell in which the anode and cathode are short-circuited; and the anode and cathode compartments are separated by an ion exchange membrane. Moreover, the provision of a copper anode and the use of a stripping solution as the anolyte allow soluble copper levels to be kept stable, thus preserving the leaching power of thiosulphate solutions, and allowing them to be recycled in a new leaching step.

IPC: H04B1/00
Filed: 2012-09-28
Abstract: Systems and methods for providing digital predistortion to compensate for a non-linearity of a power amplifier in a dual-band transmitter are disclosed. In one embodiment, a first baseband signal is tuned to a first intermediate frequency to provide a first intermediate frequency signal. Likewise, a second baseband signal is tuned to a second intermediate frequency to provide a second intermediate frequency signal. The first and second intermediate frequency signals are combined to provide a combined intermediate frequency signal. The combined intermediate frequency signal is then predistorted to compensate for the non-linearity of the power amplifier in the transmitter to thereby provide a predistorted signal. In one embodiment, a separation between the first and second intermediate frequencies and/or a sampling rate for predistortion is minimized based on a target intermodulation order for the predistortion.
