Pelletizing - Wikipedia

The formation of raw iron ore pellets, also known as pelletizing, has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference, transport, and use. Both mechanical force and thermal processes are used to produce the correct pellet properties.

Coarse Ore Feeders - Mineral Processing & Metallurgy

Once the ore has been blasted and hauled from the mine, it is sent through the milling process. At the beginning of each major stage of processing there is a holding area where the ore is stockpiled to ensure that the next phase of the process has enough material for continuous operation. The ore must then be guided through each of these different phases at a controlled even pace.

Processing of potash ore - Беларуськалий

The potash ore generally consists of sylvite (KCl), halite (NaCl – the rock forming mineral) containing the inclusions of carnalite, anhydrite and silicate and carbonate (insoluble residue).

How Is Gold Processed? |

Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.

Mineral processing - Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density.
