A Novel Approach for Beneficiation and Dewatering of Coal Fines for Indian Coal Preparation Plant

An attempt has been made to beneficiate the Indian coking coal fines by a combination of Spiral, flotation and Oleo Flotation processes. Beneficiation studies were also carried out on 0.5mm coal fines using flotation and oleo flotation by splitting at size 0.063mm.Size fraction of 0.5mm-0.063mm and -0.063mm size were treated in flotation and Oleo flotation respectively. The washability studies ...

exploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination

the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...

Use of density tracers in evaluating performance of Tri-Flo circuits Case study: Tabas (Iran) coal preparation plant

In the Tabas coal preparation plant (SE Iran), -50 + 6 mm raw coal was treated in a 700 mm two-stage two-density Tri-Flo dynamic dense medium separator. In order to study the circuit performance and to evaluate the separator efficiency, 32 mm cubic density tracers were used in the range of 1.28-2.1 g/cm3 and under different operational conditions. The performance of Tri-Flo was evaluated in a r...

Project Title : USE OF ARTIFICIAL INTELLIGENCE FOR DEVELOPING A NOVEL COAL PREPARATION PLANT SIMULATOR

Coal preparation plant simulators are computer programs used to evaluate the performance of a preparation plant for given feed coal characteristics and the type of process flowsheet selected. However, none of the commercially available plant simulators attempts to maximize the overall plant yield for alternative flowsheets and also select the most suitable circuit configuration based on maximiz...
