Potential for stratiform base-metal sulphides in SW England [PDF]

, 2004
The British Geological Survey (BGS) has recently re-evaluated the potential for stratiform base-metal sulphide mineralisation in Devon and east Cornwall (Rollin et al., 2001) (Figure 1). On the basis of their stratigraphy and tectonic setting the Lower

Quantitative leaching of galena

Bulletin of the Chemical Society of Ethiopia, 2000
Abstract (Received September 25, 1999; revised January 19, 2000) Experiments on the quantitative leaching of lead from galena in hydrochloric acid solutions are reported. The effects of contact time, acid concentration, number of leaching stages, solid to liquid ratio, particle size, temperature, and stirring speed, on the leaching reaction are ...
