In research related to pollution cleanup, a team of UMass microbiologists led by noted researcher Derek Lovley has extracted gold solids from water containing dissolved gold. The work uses technology Lovley developed 10 years ago to clean up heavily polluted water and soil around the U.S. using bacteria and archaea, or ancient microorganisms, to break down heavy metals in affected environments.
Phytomining is the use of hyperaccumulating plants to extract a metal from soil with recovery of the metal from the biomass to return an economic profit. This work looks at the possible methods for recovering gold from plant material, including chemical reduction with and without solvent extraction, thermal reduction and copper electrodeposition.

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
08-05-2020· The soil extraction test consisted of four parts. Firstly, the species, concentration and soil ratio of extraction agents were investigated. Secondly, the water bath oscillation conditions (pH, temperature, time, rotation speed) were optimized to determine the best experimental conditions. Then, the effect of Au 3+ on extraction effect was ...
