Copper and nickel slags are produced by 1 roasting in which sulfur in the ore is eliminated as sulfur dioxide SO2 ; 2 smelting in which the roasted product is melted in a siliceous flux and the metal is reduced; and 3 converting where the melt is desulfurized with lime flux iron ore or a basic slag and then oxygen lanced to remove other impurities

In contrast with the iron metallurgy the oxidation of sulphide minerals proceeds as an exothermic reaction The heat thus generated within a furnace is utilized to some extent even in the case of blast furnaces The fl ash furnace makes use of the heat of reaction to the utmost and utilizes it to melt matte and slag In order to achieve this the Outokumpu type flash furnace applies a
Slag from the reactor and the converters is sent to the concentrator to recover the copper This concentrate is fed back into the reactor and the slag tails go to the tailings pond The acid plant production is currently 525 000 tonnes sulphuric acid per year and comprises the largest gas cleaning installation of any acid plant in the world
To anticipate a possible hazard resulting from the plant uptake of metals from slag contaminated soils it is useful to study whether vegetables exist that are able to mobilize a given metal in the slag to a larger proportion than in an uncontaminated control soil For this purpose we studied the soil to plant transfer of arsenic copper lead thallium and zinc by the vegetables bean
