Mining pumps


In the mining industry, important minerals and raw materials required by today’s modern society are transported every day. Mining companies require reliable pumps for a broad range of demanding tasks to achieve a reliable operation. The tasks range from the transport of sludge via drainage up to the dosing of chemicals and subsequent neutralization. This calls for different pump technologies to be employed, which are also produced by the members of SPA.

Robustness of pumps in mining as a criterion

In the harsh environment of mines and processing plants with a variety of aggressive and abrasive media, the selection of pumps depends not only on the pump output, but also on their robustness and ease of maintenance. At first glance, mines appear to differ significantly due to their differences in natural mineral sources, which demand different conveying methods. However, many commonalities can be seen in the further processing of minerals. That also applies to the different pump technologies that are employed in the mining industry.

Successful application examples

Slurry is a mixture of pulverized rock and water. The reason for making slurry is that it is more economic to transfer slurry over longer distances rather than convey solid rock. You can use centrifugal pumps, progressing cavity pumps, rotary lobe pumps, peristaltic pumps to convey the slurry.

Other technologies:

hose pumps

Flocculants are made up and transferred in high volumes to holding tanks and therefrom dosed into the thickener to coalgulate the ore and cause the valuable product to sink to the bottom, while the clear water moves to the overflow, from where it is pumped away.
From here the valuable concentrated slurry is transferred by a pump.
