From ore to doré. More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore ...

The technological mineralogy of a gold deposit located in North-Western province of Zambia was carried out by using X-ray fluorescence spectroscopy (XRF), X-ray diffraction spectroscopy (XRD), and scanning electron microscope (SEM). The results showed that gold was highly dispersed in gold-bearing minerals such as pyrite, arsenopyrite, and some gangues in the form of natural gold and electrum.

Mineral exploration of gold, silver and PGM metal ores becomes more challenging every year. Mines increasingly facing lower ore grades and complex mineralogy, forcing mills and concentrators to process more material. Mine planning, separation and concentration are directly related to mineralogy, metallurgy and variability of the ore body.
