Geological context
Tanzania's tin deposits sit within the Karagwe-Ankole Belt, one of Africa's most established cassiterite-bearing regions. Ore is predominantly extracted by artisanal and small-scale miners across Shinyanga, Geita, and Kagera before aggregation and processing.

Every shipment is traceable to its point of origin. See Compliance & Traceability for the full chain-of-custody process.
How tin ore becomes ingot
Processed on-site through the Westfield facility, adding value to Great Lakes Region ore before export.
Step 01
Processing
Tin ore is crushed and washed to remove dust and sand, then separated from other minerals such as iron ore.
Step 02
Black Tin
Tin ore concentrate is smelted (heated up to 1300°C) to separate the metal from the remaining rock material, creating black tin - basically unpurified tin metal with 90–95% tin content.
Step 03
Ingots
Black tin is purified to produce tin metal ingots with +99% tin content.
Step 3.5
Tin Solder
Using a tin alloy of tin-silver-copper, lead-free solder bars are manufactured for use in electronic products.
