Crushing of air-cooled nickel slag produces a low quantity of finer particles, and consequently blending with additional crushed fine material may be necessary to satisfy gradation requirements. (1,5) Other nonferrous slag aggregates may also require blending with conventional granular aggregates to optimize aggregate properties.

nickel processing, preparation of the metal for use in various products.. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high melting point of 1,453 °C (2,647 °F) and a face-centred cubic crystal structure, which gives ...

Pyrometallurgical nickel industry in New Caledonia produces several tons of slag per year, which is stocked on site. There is no valorization today, except for a small transformation into sand. Pyrometallurgy highly consumes fossil-fuel energy and electricity for ore pre-treatment and nickel extraction inside electrical furnaces, which produces significant CO2 emissions.

The slag that comes off of that is not as hard and dense as steel slag. Steel slag is what happens when molten iron is introduced to other elements needed for steel, such as nickel, chromium, and manganese. The steel slag is much harder, making it harder to crush because of its higher compressive strength.

Oxides form slag that is skimmed off and is processed in an electric furnace prior to discard to recover nickel. The discarded slag typically contains 0.3–0.4% Ni, 0.2% Cu, 39% Fe, and 35% SiO 2 (Ray et al., 2014). In some nickel ore smelting, slag formation is complex because of the presence of MgO in various silicate minerals.
