Oct 1 1996 The natural maghemite from the Robe River mining district Australia is grain size dependence of the rock magnetic parameters of the maghemite is less and the raw material is brittle so very gently crushing only re
To this end more comprehensive rock magnetic data from well defined hematite and maghemite are By crushing the ore and subsequent separation into corrected for the temperature variation of the empty furnace ef AGICO manual
