·Gold mining from gold sources such as natural ores electronics and other industrial wastes is not yet feasible in terms of environmental costs and production efficiency The trace quantity of Au in the aqueous solution limits its effective capture and extraction through conventional methods Here we report a homogeneous spontaneous and selective Au
·Gold is a valuable metal extensively utilized in jewelry aerospace medicine and electronic devices Given the finite nature of gold reserves in ore and its very low concentration <10 g/t merely mining is not adequate to meet global gold supply needs [1] [2] [3] [4] The rapid growth of gold demand has promoted the development of gold recycling technology
·With the ever increasing production of electronics there is an ensuing need for gold extraction from sources other than virgin mines Currently there are no technologies reported to date that can effectively and selectively concentrate ultratrace amounts of gold from liquid sources Here we provide a blueprint for the design of several highly porous composites made
·A systematic review of gold extraction Fundamentals advancements and challenges toward alternative lixiviants August 2022; Journal of Hazardous Materials 440 6 129778; August 2022;

·In the light of mentioned above pyrolysis pretreatment of sulfide gold ore can expose the encapsulated gold Meanwhile the pyrolysis products of pyrite are self generating thiosulfate at atmospheric pressure by our proposed scheme and applying it to the green extraction of gold has become a reality Ou et al 2022 Hence the specific aim of this study is
·In order to extract gold from electronic waste first unwanted elements must be removed from the combination Thus copper silver and selenium were omitted from waste sludge using hydrometeorology method acidic leaching In this research as the aim is analyzing the extraction of gold to achieve the waste containing gold all the
·To extract gold from ore various methods are employed each suited to different types of ore and scales of production The primary goal of gold processing is to efficiently and economically recover gold from its host materials while minimizing environmental impact This passage will explore the most common gold processing methods used in modern mining and
·Gold and silver are two precious metals among the few metals that occur in nature as native forms by virtue of their chemical inactivity They are good electricity conductors in addition to their ability as optical reflectors of visible and infrared electromagnetic radiation respectively [1] At the current time both metals have various applications in different areas of life
