The results of leaching show that the combination of sulphuric acid and hydrogen peroxide enhances the dissolution of the bulk sulphide ore. The Leaching rate was studied as a function of the leaching temperature, the leaching time, the particle size and the sulfuric acid H 2 SO 4 concentration...

Sulphation roasting has been applied in extracting Ni and Mo from lateritic ores (Guo et al., 2009, Wang and Wang, 2010) or Cu from sulphide minerals (Güntner and Hammerschmidt, 2012). Galaxy Resources is using sulphuric acid to crack Li from its pre-roasted silicate host (spodumene) and...
Such a well-known acid-roasting method involves firstly decrepitation (at 1070–1090 °C) to convert α-spodumene to a more reactive β structure, followed by sulphation using sulphuric acid at 250 °C and subsequent leaching (at 90 °C) of the calcine obtained to extract lithium into ...
produce segregated particulate copper and magnetite. These double roasts provide an attractive route to copper from copper iron sulphides. However, a significant proportion of the magnetite dissolves in dilute sulphuric acid at a pH of 2.5 or less in water, so that acid leaching is not ...
