Magnetite is a ferromagnetic mineral with the chemical formula Fe 3 O 4 and the common chemical name ferrous ferric oxide which indicates the mineral comprises both a ferrous component FeO wüstite and a ferric component Fe 2 O 3 hematite Magnetite is one of several types of iron oxide and its official IUPAC name is iron II III oxide It is a member of
·The highest magnetite enrichment found at P 11 P 4 P 14 and P 5 can be attributed to the accumulation of high concentration of magnetite rich load supplied by the proximal Bhuigaon and Rangaon creek Gujar AR Ambre NV Mislankar PG Iyer SD 2010a Ilmenite magnetite and chromite beach placers from South Maharashtra Central West Coast
Wang et al conducted the oxidation of iron sand Ti−magnetite ore They found from BET tests that the hysteresis loop in the adsorption−desorption isotherms shows that the pores in the preoxidized iron sand are connected in a network whereas for the raw iron sand the pores are blocked and separated from each other
Magnetite ilmenite oxidation exsolution intergrowths from an original titanomagnetite microphenocryst from an ash flow tuff unit have been studied using conventional transmission electron microscopy and analytical electron microscopy Silicon has been found to be in solid solution in all of the magnetite studied and in some of the coexisting ilmenite The average
