Iron ore is a mineral block found underground. It is a source of raw iron, which can be smelted into iron ingots. Deepslate iron ore is a variant of iron ore that can generate in deepslate and tuff blobs. Iron ore itself can be obtained by mining it with a stone pickaxe or higher enchanted with Silk Touch. When mined without Silk Touch, iron ore drops raw …

LKAB operates two of the world's largest underground iron ore mines, the Kiruna and the Malmberget mines. Both use the sublevel caving method for ore extraction. The major iron ore being mined is magnetite with small quantities of hematite. The iron content of pure magnetite ore is 72.36% and that of pure hematite ore is 69.90% [11, 12].
An ironstone (76) is a sedimentary rock that contains more than 15% iron, ... It is only in the last 10 years or so, that coupled with the decline in reserves of high grade, BIF-hosted iron ore, have these deposits come under intense study, mainly by Australian researchers (Dalstra et al., 2010; Danišík et al., 2011; ...

What we are actually comparing is the mass per unit volume, that is, the density. In order to determine these densities, we might weigh a cubic centimeter of each sample. If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm –3 and that of the soil as 1.20 g cm –3.
