Coal pollution mitigation
Whether carbon capture and storage technology is adopted worldwide will "...depend less on science than on economics. Cleaning coal is very expensive." Conversion of a conventional coal-fired power plant is done by injecting the CO2 into ammonium carbonate after which it is then transported and deposited underground (preferably in soil beneath the sea). This injection process however is by far the most expensive. Besides the cost of the eDry coal cleaning has claimed an important place in the current coal processing technology. The most important and reliable plants include rotary breakers, air jigs, FGX Coal Cleaning an overview ScienceDirect Topics

The emission of sulfur dioxide when high-sulfur coal is burned is restricted by law. New coal-burning plants usually comply with the law by installing expensive equipment to filter sulfur dioxide from their emissions. These new plants could save money by installing instead less expensive cleaning equipment that The emission of sulfur dioxide when high-sulfur coal is burned

Coal Preparation SpringerLink
According to the annual census of coal preparation plants conducted by Coal Age [], the USA operates 286 coal preparation plants in 12 states.This number is relatively small by comparison to the worldwide fleet which is estimated to be 2,283 plants [].The capacity of the plants can range from less than 200 t/h for small operations to 6,000 t/h or more for Longwall mining additionally requires large coal reserves to justify the capital cost of longwall equipment. As surface mining in the Powder River and Rocky Mountain Basins proceeds, the “heavy-media” process using magnetite is standard for coarse coal cleaning.

Coal Cleaning an overview ScienceDirect Topics
Coal Cleaning. Coal cleaning is an option for removing mercury from the coal prior to utilization. Of the more than 1 billion short tons of coal mined each year in the United States, about 600 to 650 million short tons are processed to some degree [91 ]. Coal cleaning removes pyritic sulfur and ash. Mercury tends to have a strong inorganicHigh-Performing Bulk Carrier Cleaning Equipment.

magnetite fine-coal cleaning: Topics by Science.gov
Cleaning and dewatering fine coal. DOE Office of Scientific and Technical Information (OSTI.GOV) Yoon, Roe-Hoan; Eraydin, Mert K.; Freeland, Chad. Fine coal is cleaned of its mineral matter impurities and dewatered by mixing the aqueous slurry containing both with a hydrophobic liquid, subjecting the mixture to a phase separation. A new generation of centrifugal enhanced gravity separators is now available for fine coal cleaning. Commercially available units include the Falcon Concentrator, Kelsey Jig, Knelson Concentrator and Mozley Multi-Gravity Separator. These devices, which were originally developed in the minerals processing industry, are capable of upgradingGravity Separation Equipment: Alternatives for Fine Coal Cleaning

Coal cleaning equipment -- Performance evaluation. This International Standard describes the principles and methods for evaluating the performance of equipment used for cleaning operations. Testing and sampling procedures are specified and methods of presenting test results are detailed.Coal Cleaning Costs The costs of physical and chemical coal cleaning for sulfur removal are to a large extent undefined. Physical cleaning has traditionally been used to remove ash and mining residues from coals. There is virtually no data correlating costs and sulfur removal in commercial coal cleaning equipment.EPA's Coal Cleaning Program: Status and Strategy 1977

Impact of screening coals on screen surface and multi-index
Screening is an indispensable unit process in coal beneficiation and it is used extensively for the separation of coal particulates. It is the oldest yet most important unit operation for coal processing (Noble and Luttrell, 2015). Vibrating screen is the key screening equipment in coal preparation and its effective utilization.However, cleaning a massive mine truck is a big job. Manual cleaning can take hours and consume valuable time from both your equipment and your employees.
