Extraction of Metals from Ores – Different Processes …
The pure form of mineral from which a metal can be extracted is called the ore. Types of Ores. Given below are the types of ores with their examples- Oxide Ores- In this particular ore, the metals are present in the oxidised form. Obtaining metals from this ore is much easier. For example, Haematite ore ( Iron) and Bauxite ore (Aluminium)

Why separate Ore and Mineral holds?
Caldari = 2x Indys, both with Cargo bonuses. Gallente = 5x Indys (the old Iteron series), 2x with Cargo, 1x PI, 1x Ore, and 1x Mineral. Minmatar = 3x Indys, 2x with Cargo, 1x Ammo. Judging by this alone, they just wanted a purpose for the various Iteron hulls. But separating Ore and Minerals kinda feels like making the Ammo bays, but separating ...

Easy Ways to Extract Gold from a Rock (with Pictures)
8. Check the mining pan periodically to see if the gold is extracted. Pull the mining pan out of the water and look at the pieces that remain in the pan. Pick out any gold pieces and place them in a separate container. Continue to shake the mining pan in the water until you've picked out all of the gold pieces.

Extracting gold from rock | OpenLearn
Mercury. We used mercury to get the gold out of the powdered rock. Gold, like most minerals, can be 'dissolved' in mercury to form what's called an amalgam. An amalgam is a physical mixture, a type of alloy. This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury.
