Dewatered stockpiling (dry stacking) is a safer alternative to tailings dams (Rico et al., 2008, [3]) for tailings disposal; however, this method has not yet been used in iron ore mines in Brazil ...
Read more...Iron Ore: The King of the Dry Bulk Shipping. The iron ore is the dry bulk cargo with the largest trading volume per year, above coal and grains. Iron ore is found in nature in form of rocks, usually mixed with other elements and after it is processed by various industrial processes, it is sold to steel companies.
Read more...Dry processing is linked to the quality of the iron ore extracted from mining. 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.

ST Equipment & Technology LLC (STET) tribo-electrostatic belt separator technology allows for the beneficiation of fine mineral powders with an entirely dry technology at a high throughput. The STET separator is well suited for separation of very fine (<1µm) to moderately coarse (500µm) particles, in contrast to other electrostatic separation processes that are typically ...
Read more...Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits. STET has evaluated several iron ore tailings and run of mine ore samples at bench scale (pre-feasibility scale). Significant movement of iron and silicates was observed, with examples ...
