MINING 
JWK filter presses are used in processing plants of the mining industry due to the positive aspect of the great process-technical flexibility among other things. The most frequent applications are the dewatering of fine coal and coal tailings (finest fractions) as well as the solid-liquid separation of the ore concentrate suspension concentrated by flotation and subsequently separated from mineral by-products. At this point, metals such as zinc, iron and copper are extracted, but precious metals such as gold, silver and platinum are also extracted in corresponding mines in the form of a puncture-proof filter cake. Membrane filter presses are preferably used here to achieve quantitatively high yields in cake washing and high dry matter contents by means of squeezing processing.

This filtration is used to separate different metals. To this end, One of the metals gets dissolved and can then be removed during the filtration with the filtrate, while the other metal, that is not dissolved, remains in the filter cake. To remove the residues of the dissolved metal from the filter cake, this is washed after filtration, blown dry and be squeezed. Metallurgical industries have challenging process water conditions and the streams tend to be large containing fine particles. These kinds of waters are difficult to treat with traditional methods such as settling, because the fine particles do not settle by gravity efficiently. Therefore a method for high-rate filtration and a small footprint is crucial for increasing the water re-circulation rate at a plant, as well as the benefits of having clear water for process.

Aggregates

Aggregates like gravel and in particular sand, because of their applications, need to be washed to recover fine particles and eliminate the silt which adheres to their surfaces. Usually, the water used for sand washing can be recycled by using settling ponds in which heavier particles settle down and where they are collected from the bottom to be stocked.

JWK filter press allows to get rid of settling ponds and produces dry cakes easy to stock and dispose of, it also recovers water which is particularly important in dry areas.

JWK offers a wide range of filter press technologies – tailored to your specific needs. This includes the fields of municipal and industrial waste water, drinking water, ground water and organic waste treatment as well as sludge recycling. Our chamber filter presses and membrane filter presses are the optimal solution for your individual application due to their process variability and the waste water filter plate and filter cloth technology. These are specially designed for the best possible filtration result, high filtration rates, low energy costs and a high degree of dewatering. Efficient solid/liquid separation is of great importance not only in terms of economy but also in terms of sustainability. Accordingly, our aim with our products is to provide a far-reaching answer for the protection of the environment.
