| 摘要 |
The present invention relates to the field of mineral engineering and metallurgy in general and to extraction of metal compounds from ores or concentrates by wet processes, and more particularly to a method and an arrangement for determining of the water content of organic phase in a hydrometallurgical process. An arrangement for determining of the water content of organic phase in a solvent extraction settler (16), (19), (22), (65) according to the present invention comprises at least one electrical impedance tomography unit for measuring of the electrical conductivity of the liquid organic phase at different heights in an at least one settler cell, each of said at least one electrical impedance tomography unit comprising an electrical impedance tomography measurement probe (17), (20), (23, 25, 27, 29, 31), (35), (42), (49), (71) being arranged in said at least one settler cell after a fence structure (11-12), (66-67) and a data processing arrangement (18), (24, 26, 28, 30, 32), (72) connected to said electrical impedance tomography measurement probe (17), (20), (23, 25, 27, 29, 31), (35), (42), (49), (71); so that said data processing arrangement (18), (24, 26, 28, 30, 32), (72) and/or a measurement server (33) connected to said at least one electrical impedance tomography unit is used for determining the water content of liquid organic phase at different heights in said at least one settler cell. |
