CJ Filter Press successful application in hydrometallurgy industry

November 28 , 2022

It's critical to make comprehensive recovery of mineral and slags for sustainable development. New technology and equipment will be key factor.

In order to cater to the marketing demands, we innovatively designed the CJW washing filter press. CJW can process the washing and filtration all-in-one. The comprehensive recovery of valued metals in the slags can be possibly maximumly reached. What’s more, it will reduce secondary pollution by harmful materials, perfectly process the washing and filtration for neutralization slag, acid leaching residues, and metal tailing slags. It’s the most effective and reliable solution for hydrometallurgy.

Let's introduce the CJW to you.

filter press
