Gravity concentrates can often contain high grinding steel contents and so their removal using shaking tables or magnets is used before smelting During smelting iron can be oxidized using nitre Excessive use of nitre will corrode the smelting pot increasing both maintenance costs and the risk of catastrophic leaks known as runaways or holes in the pot through which the molten charge is lost.
