If the block is large, it is called a “quarry block” and will be cut into smaller blocks at the quarry.

iron processing Ores Britannica

iron processing iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is

2017-5-31  Answer. Quarrying Iron Ore produces often toxic waste products that can poison the environment, furthermore iron Ore in its pure form is also toxic (as demonstrated by the breaking of the dam in brazil at an iron ore plant) purifying of Iron releases harmful gases which leads to Atmospheric pollution. This 18 words question was answered by

Hydrogen Plasma Processing of Iron Ore

Iron is currently produced by carbothermic reduction of oxide ores. This is a multiple-stage process that requires large-scale equipment and high capital investment, and produces large amounts of CO2. An alternative to carbothermic reduction is reduction using a hydrogen plasma, which comprises vibrationally excited molecular, atomic, and ionic states of hydrogen, all of which can reduce iron
