Minerals Free FullText Ore Genesis of the Toudaochuan Gold
The Toudaochuan gold deposit is a recently discovered lode gold deposit in Central Jilin Province Gold ore bodies are dominantly controlled by NEtrending fault The major hydrothermal period can be further divided into the quartz–pyrite stage (stage I), quartz–gold–polymetallic sulfides stage (stage II, major gold mineralization stage), and Five geological materials, thirteen weathering profiles, and a cross section of a gold ore vein are selected to construct, test and apply a geochemical gold metallogene Five geological materials in China are acidic rock, intermediate rock, basic rock, soil, and stream sediment which elemental abundance data are excerpted in Table Construction, test and application of a geochemical gold
Construction and Application of a Knowledge Graph for Gold
Over the years, many geological exploration reports and considerable geological data have been accumulated during the prospecting and exploration of the Jiapigou gold metallogenic belt (JGMB) It is very important to fully utilize these geological and mineralogical big data to guide future gold exploration This work collects the original textual data of different gold Hydrometallurgy is a demanded method of processing gold and other noble and nonferrous metals, due to low operating costs and ease of use Based on the analysis of the literature, it can be argued that this direction is relevant and promising [2, 3]Nevertheless, the problem of creating efficient and environmentally friendly Hydrometallurgical Processing of Gold Ore SpringerLink
