Abstract
Many potentially informative studies of sulfides are handicapped by a lack of methods that readily separate sulfide minerals from one another and from coexisting silicate minerals. Simple chemical procedures were developed that: 1) selectively dissolve the sulfide fraction of comminuted silicate rocks; 2) selectively dissolve galena from ground ores; and 3) selectively dissolve sphalerite from ground sphalerite-pyrite mixtures and inter-growths. The second procedure, in particular, has proven useful in sulfur isotope studies.
