Sulfuric acid heap leaching of nickel. The technique is an acid heap leaching process like that of the copper method in that it uses sulfuric acid instead of cyanide solution to liquefy the target minerals from crushed ore. The process has been urbanized by European Nickel PLC for the rock laterite deposits of Turkey and the Balkans.
Tantalum and niobium extraction from domestic tantalite concentrates was studied by the United States Department of Interior, Bureau of Mines, using HF, H 2 SO 4, and HF/H 2 SO 4, mixtures.Sulfuric acid additions to HF greatly enhanced the dissolution rate of tantalite.

Tantalite (Fe, Mn)Ta 2 O 6 is the most important mineral for tantalum extraction. Tantalite has the same mineral structure as columbite (Fe, Mn) (Ta, Nb) 2 O 6; when there is more tantalum than niobium it is called tantalite and when there is more niobium than tantalum is it …
The decomposition was greatly improved compared to hydrofluoric acid leaching. According to our analysis, the tantalite used in this study is of a higher grade, and can only be decomposed by hydrofluoric acid, HF, or mixture of hydrofluoric acid and sulphuric acid, HF and H 2 SO 4.
The leaching reagent (dilute sulfuric acid) is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap, where it dissolves the copper from the ore. The resulting "pregnant" leach solution of sulfuric acid and copper sulfate is collected in a small pool.
