The anthracite is well suited for a new method called Pulverised Coal Injection (PCI) and in this way it is a direct substitute or partial substitute for coking coal. The advantage is that all of the anthracite mass (and mining and shipping costs) are injected into the steel, whereas with a metallurgical coal a large proportion is lost as volatiles when the coal is coked and turned into what is essentially a porous carbon foam.

For this reason, anthracite should be more economic to use compared to coking coal, on a pound-for-pound basis, but the user must have the proper equipment and needs to make test runs before committing to a large purchase. Atrum will have difficulty providing enough of its Groundhog anthracite for a test batch, but should not have an issue with providing some of the Pennsylvania anthracite that it is trying to pedal. However, the Atrum Groundhog anthracite specifications (based on laboratory analyses) look good, so perhaps a test run is not really required? This is why the Japanese have invested in Panorama.

The anthracite has value, as the previous worldwide supplier, Vietnam, has pretty much ceased exports so it can use their raw material in-country. Therefore, there is an anthracite shortage. Even though the market for anthracite is generally pushed up above the coking coal prices because of this shortage and the partial-mass-loss reason, there is elasticity to the market because anthracite can be interchanged with coking coal. This elasticity has kept the anthracite prices from soaring, IMO.

Atrum has put out good ppt presentations in the past which present these concepts - too bad they can't muster the personnel to keep up with the communications. I am available if they need some help ;-)

Yoda,

Coking coal needs to be devolatalised (have its volatile matter removed) as part of the production of metallurgical coke. Coke is used in the blast furnace. Because high grade anthracite is ultra low volatile matter and high carbon, it can displace a portion of the coke in the blast furnace, therefore indirectly reducing the amount of coking coal required (to produce coke). PCI is in theory a similar substitute, and anthracite can also be used in a PCI process, however it is not quite the same process as coke substitution. FSI is not relevant to anthracite. The important factors in anthracite are size fraction (larger lump size is much more valuable), ash (after washing), sulphur, phosporus and nitrogen. Ultra low vols is a given, as is high carbon.

Sometimes anthracite is blended with coking coal, however that is a different story again and relates to bumping carbon content or averaging down vols.

Geos are geos, you need to talk to coal marketing guys coal metallurgy people with Vietnam, North Korea or Russian coal experience to get the right information.....OR MAYBE THE COMPANY COULD DO SOME MARKETING!

Don't happen to have a feasibility study for a smelter to start using HG & UHG Anthracite, that we can organise to land in the right person's hands, do you?
