Gravity Separation - an overview | ScienceDirect Topics

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Iron is an abundant metal that is found in many museum collections. This metal is used in a variety of forms: cast iron (2.5-5 % carbon), wrought iron (0-0.07 % carbon) and steel (0.07-0.9 % carbon). Iron may also be plated with zinc. Iron and most of its alloys are susceptible to rust formation by oxygen in the presence of moisture.
