Earlier attempts at solution models for the ternary carbonate system have been unable to adequately accommodate the cation ordering which occurs in some of the carbonate phases. The carbonate solution model of this study combines a Margules type of interaction model with a Bragg-Williams type of ordering model. The ordering model determines the equilibrium state of order for a crystal from
Iron ore usually consists of iron oxides and carbonates. Its most important mineral forms are magnetite Fe 3 O 4 72.4 Fe hematite Fe 2 O 3 69.9 Fe and siderite FeCO 3 48.29 Fe. In Brail some ore that contains practically no other minerals can grade as high as 68 Fe but the crude ore mined in Canada grades between 30 and 44 Fe

2017-8-27properties that this type of ore can offer. An understanding of the mineralogy of carbonate ore and its thermal properties has provided important information which enables furnace operators to take full advantage of the chemical differences. However changes to
To constrain the thermodynamics and melting relations of the sideritemagnesite FeCO3MgCO3 system 27 piston cylinder experiments were conducted at 3.5 GPa and 11701575 C. Fe-rich compositions were also investigated with 13 multi-anvil experiments at 10 13.6 and 20 GPa 15001890 C. At 3.5 GPa the solid solution sideritemagnesite coexists with melt over a compositional
Whether a mineral can usefully be regarded as an ore or not depends on such factors as how concentrated it is its exact location and whether there is a suitable process for extracting the metal. As the more accessible higher-grade ores become exhausted less accessible and lower-grade ores are becoming increasingly utilied with a consequent shift in the meaning of the word ore
