Our processes for the treatment of anode slime have been constantly developed and improved in order to get a high recovery of gold, silver and platinum group metals (PGM). 

Outotec's know-how in precious metals has been further strengthened by the acquisition of Boliden Contech AB. As a result of this, our portfolio comprises also Kaldo treatment for precious metals in addition to TROF converting process. Both technologies have convincing reference lists.

Outotec offers technologies also for treatment of gold ore. In addition to our copper refinery slime treatment, we sell Circulate Fluid Bed technologies for roasting of gold concentrate.
