An apparatus for the recovery of gold from a gold-bearing aqueous filtrate, the process comprising the steps of: Each stage of the solvent extraction circuit and the aqueous acid scrub circuit is equipped with a mixing assembly and a phase separation tank in a head-tail arrangement such that the mixing assembly of one stage is adjacent to the phase separation tank of the adjacent stage.

Process for the recovery of gold from anode slimes

A phase separation tank for separating an aqueous liquid from an organic liquid, the tank comprising:

Phase separation tank

A process for the recovery of gold from a gold-bearing aqueous filtrate, the process comprising the steps of:

A system, device, and method include a cell-powered first electronic device for monitoring two or more electrolytic cells is powered using electrical potential imposed across the electrolytic cells. The potential is voltage-boosted to accomplish this task. If the electrical potential imposed across the cells is insufficient, the device can also be battery-powered. In any event, this device is in communication with one or more sensors in the electrolytic cells, as well as a second electronic device, and the first and second electronic devices wirelessly communicate. More specifically, the first electronic device wireless transmits data signals to the second electronic device, which receives the same. The first and second electronic devices are physically remote from one another, and they communicate over a private or public network, preferably using spread spectrum technology. In addition, the second electronic device also preferably transmits data signals to a computer for further processing of the data signals, and these arrangements can be used, for example, when producing copper.

Wireless monitoring of two or more electrolytic cells using one monitoring device

For an electrolytic cell, an apparatus and method are described that use one or more sensors to measure magnetic field strength about a conductor carrying electrical current. A processor is in electrical communication with the sensors and determines a compensated magnetic field strength based on the magnetic fields of other conductors that also carry electrical current to or from the electrolytic cell. The processor uses this compensated magnetic field strength to determine the cathode electrical current carried by the conductor and to identify open and short circuits between the anodes and cathodes of the cell. The described apparatus and method account for interactions between the magnetic fields of the neighboring cathodes.
