Abstract

Elementary and phase composition as well as micrography of the
electric furnace slag were examined. The base of slag is made from
phases containing Fe, Mn and Ca. Grains differ in size and shape,
they cling together to form bigger or smaller agglomerates, depending
on separated fractions. Relative distribution of identified phases in separated fractions is presented and the possibility of phase separation by means of successive fragmentation and sieve analysis was noticed. The slag defined in that way could find application in cement production and construction industry. The electric furnace slag deposits which pollute the water and ground as well as disfigure the environment can thus be reduced.
