some of the impurities in the charge oxidize with the fluxes to form a slag on top of the molten bath, which is periodically removed and discarded. Copper matte remains in the furnace until tapped. Matte ranges from 35 to 65 percent copper, with 45 percent the most common. The copper content percentage is referred to as the matte grade.
With less surface area, briquettes minimize oxidation and formation of slag. Because at least 90 percent of the briquette is submerged in the melt bath, the material does not have a chance to become slag. This typically produces yields between 94-96 percent, as opposed to only 45-80 percent for clean, dry turnings
