The red sand which is known as Teri sand in Tamil Nadu consists of 5.5% Total Heavy Minerals (THM) out of which 3.7% is ilmenite. The other minerals, zircon, sillimanite and garnet are in the order of abundance identified. On processing this feed to recover ilmenite by using spirals followed by dry high intensity magnetic separator and high tension separator, the ilmenite concentrate obtained c...

this study aims to investigate and optimize the effects of the main parameters including the particle size, gravity and magnetic separation combination, high gradient magnetic separation, magnetic field intensity, shaking table slope, washing water flow, and electrostatic separation upon the rare earth element (ree) recoveries from iron mine waste. the electron microprobe showed that high amoun...

Spiral gravity separators are devices used in mineral processing to separate particles based on their specific gravity or size. The spiral geometry allows for the simultaneous application of gravitational and centripetal forces on the particles, which leads to segregation of particles. However, this segregation mechanism is not fundamentally understood, and the spiral separator literatures does...

This paper extends the generalized parity vector approach for fault detection and isolation presented in Omana and Taylor [2], [3], [4], to achieve sensor accommodation. In this study, this fault detection, isolation and accommodation technique is applied to a two-phase separator followed by a three-phase gravity separator model used in oil production facilities. This model simulates a large sc...

This paper is an extension of the generalized parity vector (GPV) approach presented in Omana and Taylor [1] and [2]. In the present work, this fault detection and isolation (FDI) technique is implemented on a two-phase separator followed by a three-phase gravity separator model used in oil production facilities. This model simulates a larger scale process, which allows the technique to be test...

This paper presents an H_infinity approach for a three-phase gravity separator. A switching strategy is applied to chose between two controllers: one damp oscillatory disturbances in the inflow of separator, and better set-point tracking. The controller selection relies on disturbance measurement, which unpractical or unreliable. Therefore, H2 observer designed estimate (multiphasic) turn utili...
