Smelting - an overview | ScienceDirect Topics

Flotation concentrates undergo smelting and converting in a furnace at a temperature exceeding 1300°C to produce a silicate melt (slag) and an immiscible sulfide melt (matte) due to density differences. Limestone is added to the furnace to reduce the melting temperature of the platinum and base-metal sulfides accumulated in the matte (green matte).

Copper extraction - Wikipedia

Copper concentrates produced by mines are sold to smelters and refiners who treat the ore and refine the copper and charge for this service via treatment charges (TCs) and refining charges (RCs). The TCs are charged in US$ per tonne of concentrate treated and RCs are charged in cents per pound treated, denominated in US dollars, with benchmark prices set annually by major Japanese smelters.
