Basic Slag
From Cargo Handbook - the world's largest cargo transport guidelines website
Description
A by-product of the steel industry which, when finely ground, is used as a fertilser.
Usually packed in bags of paper or jute. Has a high density and will set hard if damaged by wetting. Slag so damaged may or may not have a value, dependent on the cost of drying, regrinding and rebagging. Contents are easily lost if bags become holed. Contact with acids gives rise to an offensive colour, which can be removed by drying, without loss of phosphate value unless the acid is toxic. See also Fertilisers, Phosphates and Superphosphates.
