摘要
There is disclosed a dry granular calcined magnetic fraction obtained from chrysotile asbestos tailings comprising as its main constituents from 25 to 43% MgO, from 25 to 43% SiO.sub.2, from 15 to 40% iron expressed as Fe.sub.2 O.sub.3, and an MgO/SiO.sub.2 ratio of from 0. 8:1 to 1.3:1, said granular material passing a 4 mesh sieve. The novel product is useful for the preparation of heat storage cores and refractory bricks for glass tank checkers or blast furnace stoves.
