Tanzania first legalized ASGM in 1995 after recognizing the sector's poverty-alleviating effect on rural populations. Government regulation requires that miners obtain a Primary Mining License (PML) to work their land or employ others to do the same. The mine site resembles a feudal economy. The License holders collect ~30% of the ore produced.

Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.
