Gold from this source is estimated to be some 5 t/year and is considered to be a by-metal with the six PGMs— namely, platinum, palladium, rhodium, iridium, ruthenium, and osmium. The igneous techniques developed for the recovery of gold from primary and secondary sources mirror the state-of-the-art in the field of extractive metallurgy.

for example, contain ca. 40 other elements [3]. Consequently, the ability to recover gold, along with other rare and valuable metals, in a sustainable manner will play a central role in the development of the metals circular economy. The dominating state-of-the-art technology for gold containing metal rich waste relies on

Since the dawn of the human history, gold has incalculable applications, especially as the prime sources of currency entry in the economics of any state [1]. Gold is a lustrous metal of great beauty that has enthused great works of art which have persisted to remain unchanged for thousands of years.

However, global demand for gold has demonstrated a notable increase, with an average annual demand of approximately 4,271 tonnes (Fig. 2 a). Additionally, global gold recycling has demonstrated a notable increase, with a near 9 % surge observed in 2023 (1237.34 tonnes) in comparison to the recycled volume in 2022 (1140.14 tonnes).
