Coal | Gekko

Coal Washing & Handling. Gekko's approach to coal handling and processing stems from a proven understanding that processing of the raw material should be determined by the characteristics of the deposit. Liberation, modularity and coarse gravity separation allow for step change benefits to green and brownfields operations.

However, column flotation is not efficient for treating fine coal containing significant amounts of mixed-phase particles. Fortunately, enhanced gravity separation has proved to have the ability to treat the mixed-phased particles more effectively. A disadvantage of gravity separation is that ultrafine clay particles are not easily rejected.

Coal preparation plant - Wikipedia

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

Heavy Media Gravity Separation - Mine Engineer.Com

Heavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 5.1) or ferrosilicon (SG 6.8), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink.
