After leaching the nickel out of the nickel speiss and turning it into nickel sulfate, the remaining precious metals residue is treated at the precious metals refinery. The copper matte is returned to the smelter. The depleted blast furnace slag is physically calibrated for use in the concrete industry or used as dyke fortification substance.
