During the exploitation of iron ore, crushing rocks generates particles of iron oxide, quartz, and clay. Depending on the granulometric classification, the tailings can be classified as fine or coarse waste (granular or sandy tailings). Iron ore with high clay content, for example, tends to generate fine particles.33

The formal exploitation of mineral resources in South Africa started with copper mining in Namaqualand (near Springbok in the Northern Cape Province) in the mid-1800s. The discovery of diamonds near Kimberley in 1867 and gold on the Witwatersrand in 1886 led to the significant growth of the mining industry in South Africa.

The quartz used by Yarimburgaz toolmakers is a semi-translucent, milky-white crystalline variety. It shows a marked tendency towards angular cleavage rather than conchoidal fracture. Unlike some types of quartz, the stone used at Yarimburgaz does appear to be relatively tough, and it is suitable for producing robust and quite regular working edges.
