Gold Ore Furthermore

Furthermore, the low gold leaching from the carbonaceous ore is probably due to the adsorption of gold–iodide species on the carbonaceous materials. This kind of adsorption has been observed by Cashion and Brown (1998) for adsorption of AuCl 4 − on modified activated carbons in an aging process over several weeks.

Solutions to this problem typically propose the use of larger sample sizes, typically 30 g or greater. 3 Furthermore, when using acid digestions, in the absence of hydrofluoric acid, low recoveries have been associated with the encapsulation of gold in the siliceous rock. 1,2,4,5 Here, it is presumed that gold is secreted within a refractory matrix, making it inaccessible to solvent …

The gold-bearing ore was heated as a thick slurry of ore, air, water and limestone in large pressure chambers. The slurry interacted with thiosulfate and a fine, bead-like material that collects the gold. At full capacity, 13,400 tons of ore can be processed daily, with leaching taking place simultaneously in two sets of seven tanks.

Gold mining has brought great wealth to human society and promoted economic development (Cosmos et al., 2020). However, the number of gold ore tailings (GOT) was, is, and will also increase rapidly with the enlargement of gold mining scale and speed.
