1. anthracite is characterized by low volatile yield, high density, high hardness, high ignition point and smokeless combustion. Black is hard and metallic.

2. Features of coal washing water: improve the utilization rate and calorific value of coal, thus reducing the transportation cost of coal gangue and further increasing the added value of coal.

Second, the application of the two is different:

1, application of anthracite: anthracite lump coal is mainly used in fertilizer (nitrogen fertilizer, synthetic ammonia), ceramics, manufacturing and forging industries; Anthracite powder is mainly used for blast furnace injection in metallurgical industry (blast furnace injection coal mainly includes anthracite, lean coal, lean coal and gas coal).

2. Application of coal washing water: it is suitable for removing impurities from coal mines and backfilling mined-out areas. Coal and gangue are separated in situ underground to realize "gangue for coal". Coal is transported to the ground, and gangue is directly filled underground without leaving the well, which can replace coal under water, roads and buildings; Avoid surface subsidence, reduce environmental pollution, and save underground and underground transportation of gangue.

Third, the overview of the two is different:

1. Overview of anthracite: Anthracite is a hard, dense and high-gloss coal mine variety. Among all kinds of coals, anthracite has the highest carbon content and the least impurity content, although its calorific value is low.

2. Overview of coal washing with water: Through the impact of water flow, raw coal with different components and specific gravity is divided into different grades, dust and gangue are removed, and ash and sulfur content are reduced, which is called coal washing with water.
