Coal agglomerates

The technology does not treat wastes but is used as a mixing apparatus in conjunction with other treatment technologies such as flotation (used to separate coal agglomerates), traditional screening, and sedimentation (both used to separate solids). 

High-volatile C bituminous coal rank of coal such that on a moist, mineral-matter-free basis, the gross calorific value of the coal in British thermal units per pound is equal to or greater than 11,500 but less than 13,000, and the coal commonly agglomerates, or equal to or greater than 10,500 but less than 11,500, and the coal agglomerates. 

Coal carbonization developed to yield coke (coal agglomerates) and byproducts. 

Development of formed coke technology, based on coal agglomerates. 

The sequence of process operations for coal agglomeration is depicted in the generalized flow diagram of Fig. 8.2. Possible equipment for each step is also indicated. In general, equipment well-known in the chemical and mineral industries can be applied in the process. The operations consist of selective flocculation or microagglomeration, agglomerate recovery with simultaneous impurity rejection, further size enlargement of the recovered and...
