A new method for gravity separation: Vibrating table gravity
The gravity method offered a sulphur recovery of about 84 wt%. The pyroanalysis of gold (Au) and silver (Ag) on the concentrate of desulphurisation with gravity methods display a gold content of 3,78 g/t and of 4,9 g/t for silver. The precious metals recovery could offset partially the costs related to the waste handling and reprocessing.

Current trends in gold recovery from electronic wastes
E-waste carries up to 10 times more excessive concentration of gold in comparison to gold ores. It approximately contains 10–10,000 g of gold/ton, whereas the gold ore contains barely 0.5–13.5 g of gold/ton.The rapid surge in e-waste generation is due to the increased usage of gadgets as well as their limited life span.

Mexico is the 9th largest world gold producer with 1016 tonnes in reserves as of 2024. 41 % losses of gold with an average consumption of 40 g/t, is due to the escape of fine AC particles because they do not have the scope to prevent the loss of particles below 0.40 mm. The recovery of gold in Mexico is becoming more important. Given the low quantities of this metal …

The highest Fe-bearing gold ore was the most difficult to extract Au in ETU/TU leaching. There are at least two detrimental factors in TU leaching of Fe-rich gold ores, that is (i) the oxidative decomposition of TU, and (ii) complexation of TU with Fe 3+, which both cause to deduce the complexation of TU with Au +.
