Tailings solutions: How to filter down the options
tailings, a filter with a large disc diameter of 5.6 m (L-type) is the appropriate filter size; this is available with one to four filter discs. A more detailed description is given by Hatzenbühler et al. (2013). These disc filters can be operated in a fully automated mode and thus can react online to changes in the filtration properties of the thickened tailings to maintain the required,
FLSmidth Filtration for Tailings Management
The Ajka Timfoldgyar Alumina Plant Tailings Dam Accident October 4th 2010 in Hungary. Hungary's government estimated that it would cost more than US$51 million and take at least a year to clean up the damage. Hungarian state news service MTI estimated at the time of the accident that Hungary stores about 50 million tons of the red tailings with about 800,000 tons
Tailings Filtration Technologies and Systems - Thickening,
Belt filters normally provide very high equipment availability compared to disc and drum filters, as they are very simple to operate and maintain. Where Cake washing is required, there many case studies where multiple disc / drum filters used for cake washing are replaced with one belt filter to filter and cake wash in one unit.

Tailings Filter Press - Dewatering Solutions for Mining Dry Stack Tailings are becoming an increasingly viable and attractive alternative to tailing impoundments in the mining industry. A Filter Press delivers some of the best results from competing dewatering technologies.
Best Practices for Tailings Dam Design - KCB
In the past, the OPEX of filter presses was considered higher than that of maintaining tailings dams. But the value is incalculable and incomparable when it comes to an extreme case caused by the rupture of a dam. With regard to the controls and associated risks, the safe stacks of dry tailings are an advantage over the dams.
A comparison of alternative tailings disposal methods,
• Filtered tailings disposal: involves removal of water by vacuum or pressure methods. Tailings are ‘dewatered’ using drum, disc, or belt filters (by vacuum) or with filter presses or belt press filters (using pressure) to slurry densities greater than 85% solids by weight. The ‘dry cake’ or ‘filter cake’ material requires transportation by truck or conveyor. doi:10.36487/ACG_rep,

The project is expected to be completed by February 2022. This new order follows a previous tailings-related order for Hindustan Zinc at its Zawar mine site in 2018. Hindustan Zinc operates beneficiation
Tailings Filter Press | Dewatering Solutions for Mining,
Dry Stack Tailings are becoming an increasingly viable and attractive alternative to tailing impoundments in the mining industry. A Filter Press delivers some of the best results from competing dewatering technologies. By dewatering tailings to a relatively “dry cake,” this stable and stackable form of storage is ideal for mining companies.
Economical dewatering of tailings for mine backfill with,
4 Filtration of gold/copper tailings with the Boozer disc filter 4.1 Filter layout In the case of a copper and gold mine, the tailings are used for mine backfill. During layout tests the tailings consisted of particles with a mean diameter size of d 50 of 20-30 microns and were thickened to >50 wt% in a thickener. Filtration tests with two tailing samples, one with a d 50 close to 20
Dry Stacking of Tailings (Filtered Tailings)
Filtered tailings allow better recovery of dissolved metals and process chemicals (e.g. gold and cyanide). Dry stack facilities are also easier to close and rehabilitate, require a smaller footprint compared to other surface tailings storage options (i.e. higher density), can be utilised in aggressive environments (e.g. undulating and steep terrain) and generate better regulator and
