Pilgangoora Lithium-Tantalum Project, Pilbara

Mining and processing at the Pilgangoora lithium-tantalum project site. Conventional open-pit mining, using truck and hydraulic excavator operations, along with drill and blast, is applied at Pilgangoora. The concentrator plant has an ore processing capacity of 2Mtpa, which will be expanded to 5Mtpa through stage two expansion of the mine.

Minerals | Free Full-Text | Geochemical Fingerprinting of ...

Columbite, tantalite and local cassiterite and wolframite are mined both from deeply weathered pegmatites and from secondary placer deposits derived from the pegmatites. The secondary deposits formed from these two types of mineralization should have distinct geochemical fingerprints as ore mineralogy in these deposits varies significantly.

Lithium Pegmatites – Is This the Right One?

 · One of the main sources for lithium is pegmatite crystals. A pegmatite is an igneous rock that is created underground when interlocking crystals form during the final stages of a magma chamber''s cooling. The name pegmatite has nothing to do with the mineral composition of the rock, but rather describes a rock''s physical structure.
