Ultracentrifugation (UC) is currently the most widely used isolation technique and is also known as the gold standard for exosome extraction and separation. UC mainly harvests the required components based on the size and density differences of each component in the original solution, so it is suitable for the separation of large-dose sample

From the framework provided by La Brooy et al. (1994), there are three main classification categories for gold ores: free-milling, refractory, and complex. Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 % of the gold, under the condition that the ore size is

Cyanide extraction of gold through milling of high-grade ores and heap leaching of low-grade ores requires cycling of millions of liters of alkaline water containing high concentrations of potentially toxic sodium cyanide (NaCN), free cyanide, and metal-cyanide complexes. Some milling operations result in tailings ponds of 150 ha and larger.
