Physicochemical constraints and fluid evolution pathways in skarn mineralization: insights from sphalerite geochemistry at the Dafang Pb–Zn–Au–Ag deposit, South China

Frontiers in Earth Science
Important Mid-Late Jurassic Pb–Zn polymetallic skarn deposits are widely distributed in South China, yet physiochemical conditions and migration of the ore-forming fluids in skarn deposits are poorly constrained. The Dafang Pb–Zn–Au–Ag deposit (38 kt Pb @

OXIDATIVE AMMONIA LEACHING OF SPHALERITE CONCENTRATE

Selçuk Üniversitesi Mühendislik, Bilim ve Teknoloji Dergisi, 2005
This paper presents a study of kinetics of leaching of sphalerite concentrate in ammoniasolutions. The effects of ammonia concentration, oxygen partial pressure, reaction temperature andparticle size on the leaching rate were investigated. The shrinking core model was applied to the resultsobtained from these experiments. Reaction on order with respect
