The Sanbao Mn Ag Zn Pb deposit located in the Laojunshan ore district is one of the most important deposits that has produced most Ag and Mn metals in southeastern Yunnan Province China Few studies are available concerning the distribution and mineralization of Ag restricting further resource exploration In this study detailed mineralogy chronology and
Opencast bauxite mining generates massive amounts of overburden and their disposal is a major concern in several countries Rahim et al 2019 The alumina industry produces 150 million tons of bauxite residue annually contributing to an estimated global stockpile of 3 billion tons Evans 2016 Due to the increasing demand for aluminum Al throughout the
The Tiemurt Pb Zn Cu deposit is situated in the southern margin of the Chinese Altay Orogen Fig 2 It was first discovered in 1987 with contained metals of Mt Pb Zn and Mt Cu Wan et al 2010a Some geological and geochemical characteristics of primary VMS mineralization are preserved at Tiemurt but the major Pb Zn Cu mineralization is adjacent to
Some sediment hosted base metal deposits specifically the clastic dominated Zn Pb deposits carbonatehosted Mississippi Valley type MVT deposits sedimentary rock hosted stratiform copper deposits and carbonate hosted polymetallic Kipushi type deposits are or have been important sources of critical elements including Co Ga Ge PGEs and Re

Pyrite geochemistry has been extensively used to reveal ore forming processes in diverse ore deposits but its application in skarn systems is not well understood The Huangshaping deposit in the Nanling Range South China uniquely develops W Sn Pb Zn and Cu Pb Zn skarn mineralization systems and both two systems have formed multi types of
In the bauxite ore The third group included As S T Fe Pb P Cu and Li which could be linked to the presence of sulfides throughout the entire studied profile and Fe minerals goethite and hematite in the iron and bauxitic clay layers The fourth group contained Ca Mn Co Ni Mo and Zn with similar vertical variations
The Miocene magmatic intrusion in the Tavşanlı zone of the Kütahya Bolkardağ Belt KBB in the northwestern region of Turkey is represented by the Eğrigöz granitoids This paper studies the petrology and geochemistry of hydrothermal alterations associated with the vein type Cu Pb Zn mineralization hosted by this pluton focusing on the determination of the mass gains and
Jinchanghe is a Zn Pb Fe Cu skarn deposit in the northern Baoshan block southwestern China It is a typical distal skarn deposit with orebodies in the Cambrian Hetaoping Formation limestone and calcareous siltstone The skarn minerals display a vertical zonation with garnet skarn in the lower part and pyroxene skarn in the upper part Economic metals are also
