After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration.

Using this system, coal gangue photoelectric separation encompasses a number of steps as an object is moved forward along a conveyor belt. Weight is first determined using the weigh-in-motion system; thus, when controller 1 receives a signal from positional sensor 1, camera 1 begins to shoot continuously and start timing.

Generation and retention of bitumen and hydrocarbons of oil window reservoirs add more uncertainty to the nanoporosity. Solvent extraction is a traditional way to regain unobstructed pore networks but may cause additional effects due to interactions with rocks, such as solvent adsorbing on clay surfaces or absorbing in kerogens.

Planning and mitigation: Splits can generally be detected using exploratory core data through correlation of coal benches and intervening rock partings. If unexpected splitting is encountered, increasing separation of coal benches above and below the rock parting generally follow directional trends.

The single float-sink test defines the relative amount of float-product and sink-reject that should result from the coal being washed in that preparation plant. The second type of float-sink analysis tests a coal sample in a succession of density baths to determine the optimal density for separation of the coal from rocks and minerals.
