Filter cake recycling recovers metals from process filtration
Filter presses in refineries, chemical plants, plating lines and wastewater treatment concentrate solids into cakes, and those cakes often carry metals from the process: nickel, cobalt, copper, molybdenum, vanadium, tin or precious metals. Compared with liquid sludge, filter cake has less water and a higher metal grade, which makes it a good candidate for recycling instead of disposal.

FAQs
Filter cake recycling: what plant managers ask
Which filter cakes can go to filter cake recycling?
Hydrometallurgical leach and precipitation cakes, plating and wastewater filter cakes, chemical and catalyst production cakes, precious metal cakes, cakes containing molybdenum, tungsten or vanadium, and used filter cloths and cartridges loaded with metal.
What analysis do you need for a filter cake?
The metal content on a dry basis, moisture, and key impurities such as sulfur, chlorine, arsenic, lead and cadmium. A safety data sheet or a description of the process helps us choose the right refiner.
How is filter cake priced?
On the payable metals in the dry cake, less processing costs, impurity penalties and moisture. Higher-grade cakes with one dominant metal command better terms. Oryx makes each offer from your analysis and volume.
Do you accept filter cake classed as hazardous waste?
Often, yes, provided the refiner is licensed for it and the export or transport permits are in place. We check the classification for your country and route and arrange the paperwork.
How do we start selling filter cake to Oryx?
Send the analysis, moisture, monthly or annual volume, packaging and photos. We reply with questions or a written offer and, once agreed, plan regular collections around your production.
Why choose Oryx Metals for filter cake?
Filter cakes are usually treated as waste because few buyers look past the label. Oryx Metals evaluates each cake for its recoverable metals, finds refiners that can process it and handles permits, so filter cake becomes a sale rather than a disposal line in your budget.
