Mozambique will take a 15% stake in domestic mining ventures and ban exports of non-processed minerals to prioritize local processing. The policy aligns with similar moves in other African nations, including DR Congo and Zimbabwe, to increase government control over critical minerals like graphite, gold, copper, titanium, and tantalum. Experts warn that smelting and refining could introduce volatility into the value chain.

DR Congo added lithium, niobium, tantalum, tungsten, and uranium to a higher 10% royalty tax bracket to increase revenue from natural resources. The move follows similar strategies by other African nations, including Ghana's sliding-scale gold royalties and Zimbabwe's lithium export suspension.
