5. Importance to the global supply of minerals
Artisanal and small-scale mining activities are also important to the global supply of minerals and metals contributing to 20 percent of annual production.
A range of metals, minerals, and precious and semi-precious gemstones are mined on an artisanal and small-scale as well as materials for industrial processes and construction.
The most common mineral mined on a small scale is gold, accounting for approximately 20 percent of world gold supply.
The sector also produces 80 percent of sapphires and 20 percent of diamonds mined in the world.
Approximately 25 per cent of global tantalum production of global tin production come from ASM.
Industrial minerals and construction materials, referred to as Low Value Minerals and Materials (LVMM) or Neglected Development Minerals, mined on an artisanal and small-scale include sand, limestone, dimension stones, and phosphate.
