The maintenance of waterways generates large amounts of dredged sediments, which are deposited on adjacent land surfaces. These sediments are often rich in metal contaminants and present a risk to the local environment. Understanding how the metals are immobilized at the molecular level is critical for formulating effective metal containment strategies such as phytoremediation. In the present w...

This study encompasses the ore mineralogy, textures and sulphide trace element chemistry of Palaeoproterozoic Lovisa stratiform Zn-Pb deposit stratigraphically underlying Fe Formation in Bergslagen province (Sweden). We investigate relative timing formation subsequent modifications its ores relation to c. 1.87–1.80 Ga Svecokarelian orogeny. The consists several different types. massive sphaleri...

Fluorite is a widespread mineral in porphyry and hydrothermal vein Mo-polymetallic deposits. Here, fluorite utilised as probe to trace the fluid source reveal evolution process Chalukou giant Mo (Pb–Zn) deposit, Northeast China, which characterised early later vein-style Zn–Pb mineralisation. A detailed rare earth element (REE) Sr–Nd isotope study of combined with Sr isotopes sphalerite conduct...

Abstract The Freiberg district hosts one of the largest series epithermal polymetallic vein deposits in Europe. availability a systematic collection historical samples provides an excellent opportunity to study anatomy these systems. Detailed petrographic investigations, geochemical analyses, and fluid inclusion studies were conducted on several vertical profiles within decipher mineralogical z...

One of the main sources non-ferrous and precious metals is sulfide ores. This paper presents a review existing literature on electrochemical properties some most common industrial sulfides, such as pentlandite, chalcopyrite, sphalerite, galena, pyrrhotite, pyrite, etc. The study results surface redox transformations minerals, galvanic effect, cathodic oxygen reduction reaction sulfides are pres...
