NETZSCH NEMO® Progressing Cavity Pumps and TORNADO® Rotary Lobe Pumps, offer the best-engineered solution for your application and ensure dependable, efficient process runs. 

Success Stories in the Mining Sector

Success Stories in the Mining Sector

NEMO® progressing cavity pump speeds up the delivery of ammonium nitrate emulsion to mining customers

Safety in mining and at construction sites where explosives are used was a problem for a long time, because the storage and transport of “volatile” explosives always constitute an enormous risk. In order to reduce the danger, there has for some time been greater use of pumpable emulsion explosives.  More...

Special base frame for reagent pumps reduces maintenance: Pump design enhances precision and reliability

Until January 2017, a copper beneficiation plant in Zambia was using pumps from six different manufacturers. Attributable to the large number of different models, this resulted in a steadily growing inventory of similar spare parts and maintenance procedures. More...

Aggressive gold sludge: Special pump technology delivers long service life without the addition of water

Global demand for gold and silver remains as high as ever. Precious metals are not only sought after by investors, but are indispensable materials in modern industry. However, mining these resources places machines under extreme stress and can increase the high price of the raw material. More...

NEMO® SY Progressing Cavity Pump prevents dangerous heat generation in emulsion explosives

Transalpine rail and road tunnels, dams for hydro-electric and storage power plants – the number of major construction sites which need significant explosive work has increased considerably over recent years. The requirements for explosives have been changing. More...

Applications in Mining

Mineral slurry transfer of all types

Regardless of the mineral slurry your are transferring, the engineers at NETZSCH pumps and Systems will select the right pump for your application. Zinc or copper, NEMO® or TORNADO® pump, you will get the best solution for your application.
