Services for

Metal refining


Hydrometallurgical processes can generate significant amounts of dissolved metals. Overtime build-up of these elements can perticipitate and impair the process efficiency or block the entire operation. 

Weeefiner offers solutions and services for recovering dissolved metals from liquid waste and solutions to ensure effective operations and to enable recycling of raw materials.

Example applications

Extend the lifetime of process liquids

Acids are commonly used in acid washing and pickling. Regular cleaning and maintenance of the process baths can help prolong their lifespan and prevent any buildup.

Weeefiner offers compact and cost-effective solutions for batch treatment. Our technology can operate in challenging feeds and remove interfering contaminants. 


  • Operational savings
  • Effective operations

Example applications

Produce recycled raw materials

High-concentration batches need to be properly recycled after usage. If the batch contains hazardous elements disposal costs can be significantly higher. 

Our state-of-the-art 4D Scavenger technology can reduce the amount of hazardous waste and transform the waste into high quality metal concentrate. Many of the metal concentrates have economic value as they could be used as water chemicals, battery materials or green transition materials.


  • Recycle raw materials
  • Reduce disposal costs
