Engineering Solutions

In mining and ore processing plants, moving abrasive slurries with a high solids content is the toughest job and determines equipment life. With mono and air-operated diaphragm pumps, blowers for flotation cells and reagent dosing pumps we provide solutions suited to harsh site conditions.

Mine sites wear equipment out faster than almost any other industry: abrasive slurries, coarse particles, remote locations and limited maintenance windows. Progressive cavity pumps handle thick slurries and tailings at low speed, air-operated diaphragm pumps cope with dry running and fluctuating levels in pit and sump drainage, and roots blowers supply flotation cells with steady, oil-free air. Dosing pumps meter collectors, frothers and flocculant. Wear parts, sealing elements and lubrication equipment are what keep these machines running in practice. For a proposal, send the slurry’s solids content and particle size, specific gravity, flow, head, pH and the available power supply.

Frequently asked questions

Which pump handles abrasive slurry with high solids content?

Progressive cavity pumps run at low speed with an elastomer stator, which limits wear on thick, abrasive slurries. For lower viscosities, air-operated diaphragm pumps are robust and easy to service. Particle size, solids percentage and abrasiveness determine stator material and the maximum recommended speed.

How is a roots blower sized for flotation cells?

Air demand comes from the cell volume and the specific aeration rate set by the metallurgist, while the required pressure follows from slurry depth, density and pipe losses. With those values and the number of cells, the blower size and any need for speed control can be determined.
