Positive-displacement pumps by NETZSCH have been used for decades reliably in the demanding mining industry. The diverse substances handled in mining include wastewater, mineral slurries, thickened sludges, kaolin suspensions, filtrates, zinc sludges and drilling muds which NEMO® Pumps are perfectly suited to transport. These abrasive and viscous substances are handled with ease.
NETZSCH NEMO® Progressing Cavity Pumps and TORNADO® Rotary Lobe Pumps, offer the best-engineered solution for your application and ensure dependable, efficient process runs.
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. 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. The sludge of crushed, gold-bearing stone that is transported for chemical extraction, for example, is extremely abrasive and can destroy pumping systems within a few days. Adding water does make it possible to convey the product, but also increases the effort required in the gold concentration process. More
Special pump for 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. Higher performance and increased safety are the overriding objectives which are demonstrated above all in the greater use of emulsion explosives. In Switzerland alone – traditionally a country with a great deal of tunnel construction – the ratio changed between 1998 and 2005 from 100 percent explosives in cartridge form to 95 percent pumped emulsions. The benefits are huge: the components, which are not dangerous individually, are not mixed until they are on site. The finished mix fully uses the whole borehole, but also goes into small openings. Certainly, high-performance, customised pumps which meet the special challenges of the emulsion matrix or of the explosive are the basis for this. More
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.

Gland seal water
The high pressure capabilities a NEMO pump allows gland seal water to be safely supplied to critical glands at pressures of up to 725 psi / 50 bar and higher. The ideal combination of high pressure, low flow rate, and pulsation free discharge, ensures ideal seal operating conditions.
