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 ...

Preparation and Transportation of Coal

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...

Survey of noise in coal preparation plants.

In response to the continuing problem of noise induced hearing loss (NIHL) among mine workers, the National Institute for Occupational Safety and Health (NIOSH) has conducted numerous noise surveys in coal preparation plants. The research, consisting of worker dose monitoring, task observations, and equipment noise profiling, was completed in eight separate preparation plants. Worker dose monit...

Preparation of coal slurry with 2-propanol.

This study explored the feasibility of using waste organic solvents as substitutes for water to prepare coal slurries. The rheological properties of coal-2-propanol slurries were examined and compared with that of coal-water slurry (CWS). The good compatibility between coal particles and 2-propanol resulted in stable particle suspension in slurry which usually exhibit Newtonian behaviour. Howev...
