Refractory gold deposits pose the biggest challenge to mineral processing plants as the particles are ultrafine and found within other types of minerals. Three factors cause gold to be refractory: physical encapsulation, chemical interference, and preg-robbing minerals.

Gold deposits. There are a number of important gold deposits in South Africa, accounting for significant gold production in the past and into the present (Janisch, 1986). The Witwatersrand Basin is host to the largest gold deposit in the world, accounting for nearly a third of the world's total gold production (Frimmel, 2005).
