Gossan ore of sulfide zinc deposit contains abundant zinc, iron, and other metal elements, which is a significant resource with complex components can be utilized. In this study, new technology preparing ferrite from gossan was proposed. The effects Al2O3, CaO, SiO2 in on the formation were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), specific surface area pore s...
The study of heavy metal speciation is of interest for the evaluation of their ecotoxicological risk. Free heavy metal ion concentrations of Cu2+, Zn2+, Ni2+ and Cd2+ were studied at different soil to soil solution ratio (SSR) to discuss metal bioavailability and toxicity in circumstance. The samples were collected from two farmed soils, impacted by a cadmium rich zinc deposit, Guizhou, China. ...
Two-dimensional polymeric nanosheets have recently gained much attention, particularly top-down nanosheets such as graphene and metal chalcogenides originating from bulk-layered mother materials. Although molecule-based bottom-up nanosheets manufactured directly from molecular components can exhibit greater structural diversity than top-down nanosheets, the bottom-up nanosheets reported thus fa...
(1) Background: The importance of Zinc in today’s world can hardly be exaggerated—from anticorrosion properties, to its durability, aesthetic, and even medicinal uses—zinc is ever-present our daily lives ever since discovery ancient times. natural, essential, durable, recyclable features zinc make it a prized material with uses many applications across wide array fields. purpose this study was ...
Zinc and its alloy coatings are commonly used to provide cathodic protection for weathering steel. However, the steel substrate corrodes faster than coating because of coating's negative corrosion potential. Many studies have examined coatings' resistance corrosion. Hot-dip galvanizing, Electrodeposition, Zinc-rich coat (ZRC) spray just some methods that can be deposit such coatings. Commercial...
