Other articles where Lump ore is discussed: iron processing: Lumps and fines: As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must.
But by the 1950s, most of the easily accessible ore with high concentrations of iron was gone, and mining companies had to dig much deeper and develop new techniques to extract and concentrate iron from lower-grade ore.
