A study on plasticity and compression strength in wet iron ore …
The most common binder in the iron ore industry is bentonite, which is a tixotrop. Bentonite is known to increase the green pellet wet-CS, dry-CS and the drop number, though with very different mechanisms. Bentonite is also known to decrease the green-pellet growth rate and influence the growth mechanisms.

Existing and New Processes for Beneficiation of Indian Iron …
In many iron ore mines, wet high-intensity magnetic separation is being preferred in the concentration of low-grade hematite ores to avoid the flotation methods. The other important factor is the selection of magnetic separator which can capture the hydroxyl-bearing iron minerals such as goethite and limonite that are feebly magnetic.

In Carajás, as the iron content is already high (above 64%), the ore is only crushed and sieved, so it can be classified by size (granulometry). In Minas Gerais, the average content is 40% iron, contained in rocks known as itabirites. To increase the content, the ore is concentrated by means of wet processing (with water).

Sinter Plant Operations: Raw Materials | SpringerLink
Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump (6.3–31.5 mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.

Dry and Wet Screening in Mining: What are the Differences?
If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you're missing several important points. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water. Extra plant capital is on the agenda when these additional stages enter.
