Mining
In ore extraction processes, part of the operation is carried out using different chemical agents to attack the mother rock and obtain, through leaching, a solution containing the corresponding mineral salts.
This process takes place under demanding conditions, in the presence of highly corrosive and abrasive solids and liquids.
The experience gained by TECNIUM in this kind of application over more than 15 years has allowed us to develop sealless pumps manufactured in specific materials, fully adapted to the requirements of the mining process.
Extreme conditions in mining processes
Leaching and ore extraction processes involve handling highly corrosive and abrasive fluids with a high solids load, which calls for specialised equipment.
Corrosive and abrasive solids and liquids
The ore extraction process by leaching uses aggressive chemical agents (sulphuric acid, acid solutions) that attack the mother rock to obtain a solution containing the mineral salts. These conditions combine intense chemical corrosion with severe abrasion from suspended solid particles.
- Pumping of fluids with a high suspended solids load
- Resistance to leaching acids (H₂SO₄ and others)
- Sealless pumps to prevent leakage
- Specific materials to resist abrasion and corrosion
- Continuous operation under extreme conditions
- Global references in copper and uranium mines
Pumps designed for mining
Conventional pumps cannot withstand mining process conditions: the combination of abrasive solids and corrosive liquids rapidly destroys mechanical seals and standard materials.
TECNIUM has developed sealless pumps, manufactured in specific plastic materials that simultaneously resist abrasion and corrosion. More than 15 years of experience and a large number of global references support these solutions.

Common questions about pumps for mining
TECNIUM mainly supplies corrosion-resistant plastic pumps designed for ore leaching and extraction processes. The range includes vertical sump pumps, vertical external pumps, standardised process pumps and motor pumps, all manufactured in specialised plastic materials engineered to withstand the combination of corrosion and abrasion typical of mining.
In mining processes, fluids contain a high load of suspended solids that are highly abrasive. Conventional mechanical seals wear out rapidly under these conditions, causing leaks and frequent shutdowns. TECNIUM sealless pumps eliminate this failure point, delivering greater reliability, lower maintenance and lower operating costs in continuous service.
TECNIUM has extensive experience and global references in copper mines and uranium mines. In both cases, leaching processes involve handling highly corrosive and abrasive fluids that require specialised pumps. TECNIUM’s technology and materials are proven in the most demanding conditions of these sectors.
TECNIUM uses specific plastic materials selected to resist simultaneously the chemical corrosion of leaching acids and the mechanical abrasion of suspended solids. The main materials include polypropylene (PP), polyethylene (PE), PVDF and other high-performance thermoplastics, adapted to the conditions of each individual mining application.
Yes. TECNIUM vertical sump pumps and vertical external pumps are designed with a cantilever shaft (sealless) allowing dry running without sustaining damage. This feature is particularly important in mining, where liquid levels may vary and the pumps must withstand periods without full submersion.
TECNIUM has its own engineering department to size and select the optimal pumps for each mining application. With more than 15 years of experience in the sector and a specialised technical team, TECNIUM can advise on material selection, hydraulic sizing and the most appropriate configuration for each mining project.
