    Low-grade ore. Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite. The ore may be easily beneficiated by

    Ore Stockpiling Why are we doing this again?

    28/04/2016· Grade Optimization: This stockpiling approach is used in situations where the mine delivers more ore than is required by the plant, thereby allowing the best grades to be processed directly while lower grades are stockpiled for a future date. Possibly one or more grade stockpiles may be used, for example a low grade and a medium-low grade stockpile. Such stockpiles may not get processed for

    Enhanced methods for nickel recovery from low-grade

    Whether high-grade or low-grade, nickel ores need to be processed after mining, in order to upgrade their nickel content from 1-4% Ni to 10-20%. Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals.
