Extraction of Iron Ore

Iron Ore

Successful Filtration of coarse and fine concentrates.

back

Iron ore is widely distributed around the world with large and numerous resources. However, the ore deposits are quite different and during wet processing there is a wide range of particle sizes that need to be treated.

For the coarse ore (d₅₀ > 100 μm), which is intended for sintering, our BoVac Pan Filters provide a reliable and economical solution for filtration and dewatering. They are specially designed for the high wear and rapid sedimentation of this product. In cold climatic zones, the use of steam cabins offers the right solution to meet the transport requirements.

The fine ore (d₅₀ < 100 μm) is ground finer and vacuum filtration is no longer sufficient to achieve the moisture required for pelleting. To meet this challenge, our most modern BoHiBar Disc filters with innovative wear protection components are the future technology. They are the right choice to produce a concentrate with the ideal residual moisture content for pelleting. If a particularly low residual moisture of < less than 3 wt.-% is required to enable transport by rail in the cold winter climate, steam pressure filtration is performed on BoHiBar Disc filters.

Applications:

coarse ore (sinter feed)
fine ore (pellet feed)

Main benefits:

high throughput
low costs with regard to CAPEX and OPEX
minimal maintenance
highest availability
small footprint
low residual moisture through steam pressure filtration allows safe transport in cold regions

BoVac Pan filter

With Horizontal Filter Surface For Ideal Filter Cake Washing.

Filters for coarse-grained and quickly sedimenting suspensions with excellent hydraulics. High solids throughputs, intensive cake washing, low residual moisture – the BoVac Pan filter guarantee high performance and reliable operation.

BoHiBar Disc filter

For Particularly Dry Solids.

Continuous pressure filtration for real challenges – such as the filtration of very fine-grained products, high suspension amounts or very low residual moisture. If faced with demanding and challenging filtration tasks and not a lot of space at hand, BoHiBar Disc filters are the right choice.

Continuous Pressure Filtration

For particularly fine particles, high throughputs and very low residual moisture.

Continuous pressure filtration with a BoHiBar Disc filter is the right solution for products difficult to filter and high suspension amounts, as for example in ore, coal or mineral processing. The BoHiBar Drum filter provides excellent results with regard to filtering and washing fine-grained products and demanding process conditions.

Vacuum Filtration. State-of-the-Art Design for High Performance.

BoVac Disc, BoVac Drum and BoVac Pan – those are continuously working disc, drum and pan filters for vacuum filtration. They are used especially with regard to continuous production processes with high throughputs.
