  • Process for macroscopically separating maceral concentrate from raw coal
    Patent number: 10906048
    Abstract: Processes for macroscopically separating a maceral concentrate from raw coal are disclosed. In some embodiments, a process includes the following steps: crushing and sieving the raw coal to obtain a first coal sample and a second coal sample; subjecting the first coal sample to a heavy medium cyclone separation process; and subjecting the second coal sample to a froth flotation process. The first coal sample has a particle size within a first particle size range, and the second coal sample has a particle size within a second particle size range. In other embodiments, the froth flotation process uses a froth flotation agent including a foaming agent and a collector. The foaming agent includes at least one item selected from the group consisting of 2-octanol, terpenic oil, and polyethylene glycol (PEG). The collector includes at least one item selected from the group consisting of kerosene, diethyl phthalate (BET), and diesel.
