EXCLUDING mechanical, smelting, and amalgamation processes, the methods of extracting gold from its ores may conveniently be grouped together under the heading of wet or chemical methods. In these, ...

Forward-looking: A team of Australian researchers has unveiled a breakthrough method for extracting gold that could dramatically reduce the environmental and health hazards long associated with mining ...

At Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool ...

Refractory gold ores present significant challenges to conventional extraction methods. In these ores, gold is tightly encapsulated within sulphide minerals or locked by carbonaceous matter, thereby ...

Quantitative models show that New Kingdom expeditions in Nubia achieved significant profits, with alluvial mining in streams and the Nile as the most productive sources, challenging previous theories.
