Therefore, dewatering after 1250 kPa filtration has no further adhesion-increasing effect. For the iron ore tailings, 5 kN·m −2 corresponds approximately to 25 cm cake thickness by assuming a residual moisture of 20 w-%, ρ Solid of 3050 kg·m −3, ρ Fluid of 1000 kg·m −3, a full saturated cake (S = 1) and no sealing edge.
Iron ore processing is a crucial step in the production of steel, one of the most essential materials in modern society. Iron ore, a naturally occurring mineral composed primarily of iron oxides, is mined and processed to extract iron for various industrial applications.
The demand for iron ore has increased dramatically in the last years and is forecast to remain on a stable high production level for years to come. It's expected that the world economy is facing a stable continuous growth of iron ore to two billion tonnes and more over the next decades (Beddows, 2007). Furthermore it is expected that the existing and …
Concentrate dewatering: Higher throughput, lower cost cakes, or feed for other processes, reliability is everything. In addition to consistently high throughputs with …
