Zinc Phosphate Nanoparticles Produced in Saliva

European Journal of Inorganic Chemistry, Volume 2020, Issue 38, Page 3654-3661, October 15, 2020., 2020
Water‐soluble zinc compounds are frequently added to food and cosmetic products as trace element supplements. They form nanoparticles upon contact with saliva. Their chemical and structural evolution was subsequently followed using small‐angle X‐ray scattering and X‐ray absorption spectroscopy.

Multianalysis Characterization of Mineralogical Properties of Copper‐Lead‐Zinc Mixed Ores and Implications for Comprehensive Recovery

Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020
Copper‐lead‐zinc mixed ore in Tibet, China, is a complex and refractory polymetallic ore resource; thus, ascertaining its mineralogical properties is very important for comprehensive recovery of valuable elements. In this work, the mineralogical properties of this copper‐lead‐zinc mixed ore have been characterized in detail following a ...

Concentrating Mill Wastes are the Source of Pollution of Human Environment and Natural Ecosystems with Heavy Metals: A Case Study in Primorsky Krai, Russian Federation

Journal of Chemistry, Volume 2020, Issue 1, 2020., 2020
Elevated contents of hazardous elements in natural ecosystems are often associated with human activities. Significant quantities of these elements, including heavy metals, are concentrated in tailings. The goal of the study was to assess the mineralogical and geochemical features of the old tailings of the decommissioned Krasnorechenskaya concentrating
