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 ...

The process is generally performed on gold-bearing rock where the powdered gold fragments are so fine that other extraction methods would be less effective.

Progress roundup: Resources like water in the desert and gold trapped in e-waste are recovered in new ways. And globally, more children are in school.

The project team, led by Matthew Flinders Professor Justin Chalker, applied this integrated method for high-yield gold extraction from many sources – even recovering trace gold found in ...

In a groundbreaking scientific development, a strain of bacteria that can produce pure gold has been discovered. This finding ...

Researchers from the University of Flinders in Australia have developed a safer method of gold extraction and recovery from ore and electronic waste.

This discovery may also help better understand the distribution of gold in other minerals, which may lead to more environmentally friendly gold extraction methods.

Millions of tons of electronic waste are produced every year, translating to millions of tons of possible sources of gold. Researchers have come up with a new gold extraction method that is ...

According to research released yesterday, small-scale gold mining has led to the destruction of more than 170,000 acres of primary rainforest in the Peruvian Amazon over the past five years ...
