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.
