When gold is extracted from the earth, it is often attached to a variety of other minerals. A gold nugget, for example, is likely to have a purity of just 70 to 90%. In many cases, gold occurs in low-purity ore in the form of flecks or fine grains. Vast quantities of soil or sediment must be processed to find tiny quantities of gold.
The motivation for both is generally to increase the plant throughput. Crucial in this aspect is that the viscosity modifiers must not influence the gold adsorption capacity of the activated carbon used. In this work the fraction adsorbed gold is determined in the presence of typical concentrations of viscosity modifiers in a model slurry.
