Assessment of Blood Lead Levels Among Children Aged ≤5 ...

This assessment found that most families are using safer ore processing methods and blood lead levels among young children are lower than those found in 2010. Only 20 families (5%) were processing ore within the family compound, where children aged ≤5 years spend most of their time, compared with 84 families (71%) in 2010.

Silver processing |

Silver processing |

A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.
