The Y values reflect proportions of the ore's specific generator, i.e. if a deposit uses the sea level generator, then 0.5 is half the world's sea level and 1 is one block above sea level. For example, on a default 256-block high world, an ore with a Y range of 0 - 0.85 using the "anywhere" disc generator can spawn anywhere between 0 - 218 ...

Magnetite ore and processing. A general processing circuit for magnetite ore is initial crushing and screening of run of mine (ROM) ore to <6 mm. The ore is then milled to a specified grind size to liberate the iron minerals from the gangue, then processed further to produce a magnetite concentrate, commonly by a wet magnetic separation process.
