Observability study of the circuit variables in the dry tailing processing (DTP) of Golegohar iron processing plant using linear and bilinear methods

چکیده مقاله

To carry out metallurgical and economic calculations as well as plant control, mass balance for mineral processing circuits is a very important and fundamental issue. For this purpose, sufficient and correct data from mineralprocessingcircuitsarenecessary.Ontheotherhand,due to economic or technical reasons, measurement or sampling fromallofcircuitsisnotpossible.Inthispaper,regardingthe measurement or sampling system that has been installed in the mineral processing circuit, a basic cycle matrix method was used for the determination of observable and unobservable variables in the mineral processing circuit. Also, two newmethodsincludinglinearandbilinearmethodswereused for calculation of observable variables. These methods have been used in the case study related to dry tailing processing of the Golegohar iron processing plant
