 · 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.

A population balance model can incorporate each of these key factors. The power of the model not only helps to predict gravity gold recovery but can also assist in trouble shooting existing circuits. The GRG Test (Ore Characterization) The gravity-recoverable-gold content of an ore, as obtained via a GRG test, provides a quantitative theoretical limit of gold that …
