An expert system, for fault diagnosis of shaking table operations, is presented. The system is designed as one element of an integrated, computer-based method for plant enhancement, for application in the mineral processing industry. The relationship between expert and conventional software techniques is discussed. The system is based on prod uc tion rule s and has been wri tten in the PROLOGla...

this study aimed to explore concentration of a low grade sulfide-oxide lead-zinc sample containing 2.3% pb, 1.91% zn taken from changarzeh mine, south natanz, iran. the effects of different parameters such as type and dosage of collector, milling retention time, dosage of sodium sulfur and its preparation time, application of sodium silicate, ph and solid content were investigated in relation t...

this study contains the identification of modal dynamic properties of a 3-story large-scale steel test frame structure through shaking table measurements. shaking table test is carried out to estimate the modal properties of the test frame such as natural frequencies, damping ratios and mode shapes. among many different model structures, arx (auto recursive exogenous) model structure is used fo...

This paper presents a dynamic nonlinear numerical simulation of a 5-story full-scale steel frame structure based on Perform-3D. Flexibility-based fiber element and Maxwell model are adopted for structure member simulation after a post analysis of the shaking table test of a 4-story full-scale steel frame. The author simulates the low cyclic reciprocating load test for the steel members with fib...

In the present study, the possibility of concentrating tungsten-copper vein ore in South Chah-Palang was examined using gravity separators including Jig Machine (-2360+600 μm), shaking table (-600+120 μm), and multi-gravity separator (MGS) (-120 μm). The representative sample contains 1.5% WO3 and 5.95% CuO. The main tungsten minerals were ferberite and wolframite and their appropriate liberati...
