Recovery of magnetite-hematite concentrate from iron ore …
already been grinded, separation process requires much less energy and can also decrease total costs of concentrate production. Due to gradual depletion of iron ore reserves, more studies are devoted to tailings processing [3-7]. The results of these works indicate the potential recovery of iron ore concentrates from mining-induced mineral

Extracting gold: the basics, the methods and the technology
The 3 phases of gold processing. Gold processing generally occurs in three phases: extracting gold from the ground, refining, and manufacturing. Extracting gold begins in open-pit or underground mining. Then, the gold is separated from the gold-bearing rock with chemical processes involving toxic substances like cyanide leaching, zinc dust, and ...

Iron Ore Processing, General | SpringerLink
The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.

Ore Processing Concepts
At IV and beyond (up to a point), single-block machines are no longer acceptable for the amount of ores we will be processing, and instead we will move on to the GT++ multiblock machines. These are: Ore Washing Plant (OWP) Maceration Stack (MS) Large Thermal Refinery (LTR). This is the multiblock thermal centrifuge.

What happens to the ore-processing facilities of Deep Space Nine?
In "Progress" Bajor's fifth moon Jerrado is mentioned. Thus the number of Bajoran moons changes. The logical explanation is that the Cardiassians moved ore-rich asteroids into orbit around Bajor as temporary moons and mined them to pieces. Thus asteroids could have been moved to DS9's new position to continue the ore processing, …

Ore Processing | OceanaGold
Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.
