Abstract:
A method and to an arrangement for recovery of precious metal. The method includes calculating a first electrical property of a slurry downstream of a retention screen in a first flow direction A either (i) based on a first difference between the first supplied current and the first received voltage, or (ii) based on a first difference between the first supplied voltage and the first received current, calculating a second electrical property of the slurry upstream of the retention screen either (i) based on a second difference between the second supplied current and the second received voltage, or (ii) based on a second difference between the second supplied voltage and the second received current, and calculating the adsorption particle content of the slurry upstream of the retention screen based on a difference between the first and the second electrical property.

Claim (Index 53):
A system for recovery of precious metal, wherein the system comprising:\n a plurality of adsorption vessels arranged in series, wherein each adsorption vessel comprises a reactor space, a closed retention space within the reactor space, a retention screen between the reactor space and the closed retention space, first inlet means for feeding slurry containing precious metal into the reactor space, second inlet means for feeding adsorption particles into the reactor space, first outlet means for feeding slurry containing precious metal from the closed retention space, and second outlet means for feeding adsorption particles from the reactor space, slurry containing precious metal in the reactor space of each adsorption vessel, adsorption particles in the reactor space of each adsorption vessel, wherein the precious metals are adsorbed onto the adsorption particles, a first drive system for moving the slurry through the plurality of adsorption vessels in a first flow direction A so that the slurry moves through the retention screen in the reactor space of each adsorption vessel, wherein the adsorption particles cannot pass through the retention screen whereas the slurry passes through the retention screen, a second drive system for moving the adsorption particles through the plurality of adsorption vessels in a second flow direction B that is opposite the first direction, comprising in at least one adsorption vessel of said plurality of adsorption vessels first electrodes of a first probe in electrical contact with the slurry downstream of the retention screen in the first flow direction A, wherein the first electrodes of the first probe are either (i) configured to supply a first supplied voltage to the slurry downstream of the retention screen in the first flow direction A, and configured to receive a first received current from the slurry downstream of the retention screen in the first flow direction A or (ii) configured to supply a first supplied current to the slurry downstream of the retention screen in the first flow direction A, and configured to receive a first received voltage from the slurry downstream of the retention screen in the first flow direction A, comprising in said at least one adsorption vessel of said plurality of adsorption vessels second electrodes of a second probe in electrical contact with the slurry upstream of the retention screen in the first flow direction A, wherein the second electrodes of the second probe are either (i) configured to supply a second supplied voltage to the slurry upstream of the retention screen in the first flow direction A, and configured to receive a second received current from the slurry upstream of the retention screen in the first flow direction A or (ii) configured to supply a second supplied current to the slurry upstream of the retention screen in the first flow direction A, and configured to receive a second received voltage from the slurry upstream of the retention screen in the first flow direction A, a data processor device functionally connected with the first probe and with the second probe, the data processor device being configured either (i) to calculate a first electrical property of the slurry downstream of the retention screen in the first flow direction A based on a first difference between the first supplied voltage and the first received current or (ii) to calculate a first electrical property of the slurry downstream of the retention screen in the first flow direction A based on a first difference between the first supplied current and the first received voltage, the data processor device being configured either (i) to calculate a second electrical property of the slurry upstream of the retention screen in the first flow direction A based on a second difference between the second supplied voltage and the second received current or (ii) to calculate a second electrical property of the slurry upstream of the retention screen in the first flow direction A based on a second difference between the second supplied current and the second received voltage, and the data processor device being configured to calculate the adsorption particle content of the slurry upstream of the retention screen in the first flow direction A based on a difference between the first electrical property and the second electrical property.
