 — If too much water mixes with iron ore, it becomes low grade and unsuitable for export, which results in massive revenue losses. Also, surface dewatering processes are extremely costly if the water is very high. The accepted dewatering process within the region is to pump the water out through boreholes. However, this is not without its …

 — Excess water produced during dewatering is increasingly used for water supply, industrial processes or agriculture, and at some mines where water is too salty or brackish, desalination is an option. But in some cases, such as Rio Tinto's Yandicoogina iron ore mine in the Pilbara, water is discharged along natural creek lines under licence.

dewatering solution for ultrafine iron ore. Dewatering of iron ore slurry by a ceramic vacuum disc filter271 Кб. Overall capacity of the filter and residual moisture content of the iron ore cakes were used for describing the performance of the filter.One of the most important applications of ceramic disc filters is the dewatering of iron ore slurries.

 — ABSTRACT The present investigation aimed to understand dewatering amenability of the tailing slurry generated during the beneficiation of chromite ore. The tailing includes mainly ultrafine particles with a concentration of Cr+6 which causes environmental and storage issues. Several dewatering techniques were investigated, …

 — Flocculants play an important role in the solid-liquid separation of tailings slurry, and its dosage directly impacts on the dewatering efficiency of tailings. Herein, …

 — High water usage is necessary while ore passes through the many stages of a mineral processing plant. However, a dewatering system filters the final ore pulp product to remove the water, which is reutilized in the previous processes. This step is fundamental to reducing the fresh new water consumption. Usually, several tanks, pumps, and filters …

Concentrate dewatering: higher throughput, lower costs. Dewatering iron ore concentrates is a crucial step in enhancing their handling and transportation by removing excess water. The selection of a suitable dewatering method depends on various factors, including moisture content, particle size distribution, and downstream process requirements.

Screening is mainly used in the mining sector in primary and secondary crushing systems (Fig. 3), coarse screening (scalping) in the pre-heap leaching process, fine screening and fine-grain elutriation in various process stages, enrichment of valuable materials, e.g. of the iron content in iron ore, grinding and screening circuits (open and ...

Further, recent tailing dam failures have drawn attention to the need for an efficient scientific process ...

Hydrocyclones are ideal for recovering down to 400 mesh (38µm) particles of 2.7 SG. This is typically done in the form of an Ultra Fines Recovery system comprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90% passing 400 mesh (38µm) and a product discharging the screen in a drip-free, …

The slurry settling characteristics are the most important to design a thickener in process industries. In this work, the iron ore slurry from the screw classifier overflow was used for the settling study. It was observed that the original slurry exhibited a low settling velocity and a turbid supernatant during the settling process. Commercial flocculating agents …

Many iron ore mines reached the water table in the 80's, developing hydrogeological studies to promote the mine's dewatering. These studies improved a lot the understanding of the groundwater behaviour of the Quadrilátero Ferrífero. This is the case of Minerações Brasileiras Reunidas S/A – MBR, an iron ore mining company that, during ...
