Custom smelters
Smelters can be classified into two types depending on their business model; custom smelters and integrated smelters. A custom smelter is a smelter that treats ore on behalf of customers or buys ore for treatment. Custom smelters obtain ore concentrates from mines of different ownership. Integrated smelters depend directly on a specific mining operation and tend to be located next to a mine.
