The present work is concerned with sulfidation of Cu, Zn and Ni containing plating wastewater with CaS. The sulfidation experiments were carried out at a room temperature by adding solid CaS to simulated metal solution containing either single-metal of Ni, Zn and Cu, or Ni-Zn-Cu mixture. At first, the experiments were conducted without pH adjustment and it was found that the complete sulfidatio...

На Большом Кавказе описаны различные месторождения и рудопроявления золотого оруденения, в том числе эпитермального. Однако типизация золото-серебряного эпитермального оруденения с использованием физико-химических условий их формирования на современном уровне не проведена. Целью исследования является получение комплексной геолого-минералогической физико-химической характеристики руд уровне. Объ...

Two-dimensional and layered MoS2 is a promising candidate for next-generation electric devices due to its unique electronic, optical, and chemical properties. Chemical vapor deposition (CVD) is the most effective way to synthesize MoS2 monolayer on a target substrate. During CVD synthesis, sulfidation of MoO3 surface is a critical reaction step, which converts MoO3 to MoS2. However, initial rea...

the base (cu–pb–zn) and precious metals (ag±au) mineralization at the no. 4 anomaly of golojeh deposit occurred in volcanic and sub–volcanic eocene–oligocene host rocks, in the central part of the tarom–hashtjin zone. basic to intermediate volcanic, volcaniclastic and sub–volcanic rocks are dominated in the area and include andesite, basaltic andesite, trachy-andesite, dacite and tuff with affi...

Čukaru Peki is a recently discovered porphyry- high-sulfidation Cu-Au deposit located 5km south of the mining town Bor in east Serbia. Three styles mineralization are distinguished system: type with massive sulfides (named Upper zone), porphyry Lower zone) and transition (between porphyries sulfides). This study investigates concentration distribution trace elements pyrite from these three zone...

In order to study the sulfidation of a catalyst fixed bed, an in operando single pellet sensor was designed. A catalyst pellet from the fixed bed was electrically contacted and its electrical response was correlated with the catalyst behavior. For the sulfidation tests, a nickel catalyst was used and was sulfidized with H₂S. This catalyst had a very low conductivity in the reduced state. During...

The Suyoc prospect is an epithermal vein-type mineralization located at the southern part of Mankayan Mineral District, Northern Luzon, Philippines. prospect’s veins are hosted in volcaniclastic rocks and conglomerate, which belong to Late Oligocene Early Miocene Balili Formation Middle Conglomerate, respectively. These classified into three major types: quartz vein, quartz-sulfide quartz-carbo...
