Two commonly noted phenomena are the reorganization of exsolution bodies and the destruction of colloform textures.... A general decrease in the incidence of colloform textures with an increasing grade of metamorphism has been reported from pyritic deposits in the Urals, Japanese sulphide deposits and Canadian Precambrian volcanic masive sulphide deposits. Both these adjustments generally improve the ores from the point of view of the mineral processor. Exsolution bodies do not pass with their host grains into the wrong concentrate and the replacement of colloform textures by granular intergrowths leads to better mineral separation during grinding. 1, record 9, English, - colloform%20texture

Another form of expressing iron ore prices is cost per iron ore unit, which is a more universal convention that can be used to compare ores with different grades in each product form. One metric ton iron unit consists of 1% iron in the metric ton of ore or, expressed directly in weight, one metric ton unit consists of 10 kg of iron.
