Coltan / Tantalite
Characterized by a refractory nature, low natural abundance, extensive solid solution, few known deposits, sporadic supply and difficult metallurgy, tantalum is a complex, high tech metal of the future.
Tantalum and niobium processing can be difficult because the minerals are brittle, heavy and typically highly intergrown with sulfide and other oxide minerals. East African Precious Metals has contributed to many tantalum projects over the years and can bring an integrated suite of services to tantalum and niobium exploration or development projects.
Early identification of the tantalum or niobium minerals in an ore as well as their deportment, textural associations and micro-chemical composition plays a critical role in determining a deposit’s amenability to metallurgical processing.
