Product information
This heavy-duty industrial basket strainer is specially designed to operate in the extremely harsh and aggressive conditions of the mining industry and to filter liquids with high precision in laboratory research. Made entirely of high-quality stainless steel, it reliably retains solid particles in slurry, process water, and acidic and alkaline solutions.

Applications and functions in the mining industry
- Flotation and beneficiationCleans ore slurry (sludge) and process water of large rock fragments before they are fed to hydrocyclones, pumps and flotation machines.
- Hydrometallurgy and solution filtrationRemoves mechanical impurities from the aggressive acidic, alkaline and cyanide process solutions used to recover gold, copper and other non-ferrous metals.
- Protection of pumping stations and nozzlesReliably protects drilling rigs and quarry drainage pumps from abrasive wear by sand and rock particles.
Role in laboratories and pilot test sites
- Sample beneficiation and analysisSeparates coarse sediment from ore samples after chemical treatment under laboratory conditions.
- Multi-stage filtrationWith fabric or polymer laboratory bag filters installed in the housing, it provides ultra-fine filtration at the micron level (0.5–100 µm).
- Process modellingAn ideal device for testing large-plant filtration processes at laboratory scale and determining the composition of solutions.

Advantages for mining and laboratories
High mechanical strength
Fully withstands intense rock abrasion (abrasive wear) and water hammer.
Chemical inertness
Stainless steel does not react with the reagents or laboratory samples being filtered, which keeps analysis results accurate.
Cost-effective and eco-friendly
The stainless-steel basket inside the strainer is washed and reused many times, sharply reducing consumable costs.
