Iron oxide‑copper‑gold (IOCG) deposits are a rare type of magmatic-hydrothermal deposits that were initially proposed for the giant Olympic Dam deposit and Cu-Au deposits in the Cloncurry region, Australia (e.g., Hitzman, 2000; Williams et al., 2005; Groves et al., 2010).They are commonly hosted within breccia bodies and are related to regional-scale hydrothermal …

Recycling Efficiency. Recycling Efficiency is the percentage of used materials, that can be re-used by recycling them. The initial value of 25% can be raised up to 90% using different Edicts and Research.. An efficiency of 25% means that for every 100 Iron used by a machine, 25 Iron can be created by processing the Recyclables from that machine in the Waste Sorting Plant.

gold uptake from 96.5 % (by ICP-MS) at 5.0 ppm HAuCl 4 to 83.3 % at 1.0 ppm, with 24.7 % uptake seen at 0.1 ppm (Table S1, Figure S2). It is therefore evident that while this method is effective for recovering low concentrations of gold from solutions relevant to e-waste recycling it is not usable for trace gold uptake. The gold-containing ...

5. Be Aware!! Metal ore deposits are a finite resource (there are only a certain amount of them) and non-renewable (once used, they are gone and will not be replaced). Many metals are obtained today from recycling (melting and refining) scrap metals. Native Metals: Gold and platinum occur in the Earth as native metal, which means that they are found as the element, …

The average grade of gold ores has been falling over the years. Between 1830 and 1900, the average grade of gold ore was around 20 g/ton and in 2000; it had dropped to around 3 g/ton (Muller and Frimmel 2010). Gold mining companies are processing lower grades of ore as the higher-grade ores are getting depleted.
