Graphite-containing refractories are sometimes also recycled, but often not because of their graphite: the largest-volume items, such as carbon-magnesite bricks that contain only 1525% graphite, usually contain too little graphite.
Since much of the lost capacity was for carbon-magnesite brick, graphite consumption within refractories area moved towards alumina-graphite shapes and monolithics, and away from the brick.
It is involved in the exploration of iron ore, copper, rock phosphate, limestone, dolomite, gypsum, bentonite, magnesite, diamond, tin, tungsten, graphite etc.
The pyroxenite from 170.9 to 302.05 was subjected to shearing, alteration and veining resulting in a quartz-magnesite-talc breccia with occasional disseminated sulphides and fuchsite.
