Water is required for all types of mining
It is impossible to exaggerate the relevance of Netsol's wastewater treatment for non-metals and ferrous applications. When there is a lot of rain, acid overflow from mine drainage, tailings heaps, and surface mines can damage streams and rivers in specific places. In dry places, ores mining and processing consume a large amount of scarce water.
What Are tailings Dams and why are they so risky?
Tailings are slurries of concentrated water, silt, and gravel that are produced as a by-product of mining operations. Tailings must be appropriately handled after removing any important metals from a mine, as they are unstable and cannot be easily integrated back into natural mineral basins.
Many mining operations invest in tailings dams or infrastructure to control these wastes. These dams, on the other hand, fail at a far higher rate than most other types of dams, posing a serious threat to both humans and the environment. The most vulnerable dams are those located upstream.
What are more effective mining wastewater water treatment options?
Rather than relying on tailings dams, companies offer a wide range of improved mechanical filtration options for better tailings management, including:
· Hydro cyclones: for low-cost tailings management that can remove large amounts of solids without the use of chemicals.
· Belt Filters are ideal for tailings management since they have a small footprint and need little initial investment.
· Filter presses are useful for practically any mining activity and are great for removing solids at low and high pressures.
Filter press for mining industry
A filter press is one of the most well-known and reliable types of dewatering equipment. It's employed in a range of industries and applications for wastewater treatment. A filter press removes pollutants and suspended sediments from industrial effluent by separating solids from liquids. This makes it simple for plant managers to handle and dispose of trash while yet returning clean water to their systems.
Liquids and solids are separated using filter presses. Specifically, the filter press uses pressure filtration through a filter media to separate liquids and solids. The slurry is then poured into the filter press, where it is dewatered under pressure.
What are the four main filter press components?
• Filtration Plates
• Diverse (piping and valves)
• Filtration Cloth
What is the purpose of a filter press?
While different types of filter presses work in different ways, they all follow the same principles. A feeding pump is used to pump slurries of water mixed with particles into the press. Pressure from a centrifugal pump or similar equipment drives the slurry through chambers composed of filter plates once within the press. As "filter cakes" of solids pile up on the machine's filters, pollutants are removed from the water.
When the chambers of a filter press are filled, the machine's filtration cycle is finished, and the filter cakes are released. These cakes are simply removed, allowing for high-efficiency water filtration. In filter presses, fast action automatic plate shifters can help speed up cake removal and cycle time. In tougher settings where continuous operation is required, such as mining processes or chemical production plants, a completely autonomous filter press design is required to satisfy the 24-hour demands.
The filter cloth should be specifically developed for your application and the types of solids you are filtering to obtain the maximum performance out of your filter press.
Our team of water treatment professionals at Netsol Water can help you combine your dewatering efforts with a thorough water treatment that optimises your systems. We can perform a chemical analysis of your water to determine the best flocculants, coagulants, and pH balancers to utilise, to treat it before it goes through mechanical separation. This improves the effectiveness of your clarifiers and filter presses, resulting in a more effective and efficient total water treatment.
Aside from chemical goods, Netsol is a liquid and solid separation expert, with a variety of filter press types and capacities to meet individual application needs for trouble-free, cost-effective dewatering.
