USA Coal cleaning by gaseous carbon dioxide ...
A process for froth flotation of coal using gaseous carbon dioxide includes a preconditioning treatment of the coal with gaseous carbon dioxide followed by froth flotation, preferably also using gaseous carbon dioxide. The pretreatment causes the coal to show improved results in that less reagent promoter and frother are required, and the flotation time is reduced.

Difference Between Ductile Iron and Cast Iron
Ductile iron consists of iron, carbon, silicon, manganese, magnesium, phosphorous and sulphur. Tin and copper are also sometimes found. Ductile iron also consists of nodular graphite, which gives it flexibility. Cast iron mainly consists of carbon and silicon. With regard to practical uses, ductile iron pipes are used in sewer and water lines.

Primary graphite can easily occur in ductile iron if the carbon equivalent is too high in relation to the cooling rate. Primary graphite can be the cause of casting defects such as shrinkages and carbon flotation. Let us compare two cases:: Assume a hypereutectic alloy with C= and Si= giving CEL=% (see illustration).
