The content of base metals in ore deposits is getting lower. Therefore, preparation processes are improved and the ores are finely grounded to achieve the highest possible yield. This increases the demands on the filtration technologies, as increasingly fine and very fine suspensions must be filtered.

BoVac Disc and BoHiBar Disc Filters master these challenges and deliver the best results in the dewatering of fine-grained and coarse-grained concentrates: high specific throughputs, adjustable final dryness, clear filtrates, economical and resource-saving operation.

If very low residual moisture of the concentrate is required, steam pressure filtration is performed on BoHiBar Disc filters. This unique process is the most economical choice for achieving particularly dry concentrates. In this case, thermal drying can be omitted.


  • concentrates from base metal processing

Main benefits:

  • high throughput
  • low costs with regard to CAPEX and OPEX
  • minimal maintenance
  • highest availability
  • small footprint
  • lowest residual moisture, especially when using steam pressure filtration

BoVac Disc filter

For the Filtration of High Suspension Amounts.

BoVac Disc filters are used for the filtration and dewatering of high amounts of suspensions. The enormous filter surface allows high specific throughputs. Due to the modular construction, the filters can be adjusted to various process conditions.

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.
