Maximum gold recovery at a very minimal cost in a much safer way is the prime goal of any gold processing operation. Intensive cyanidation on gravity recoverable gold is the best for maximum recovery (cost on reagents), yet, it produces a pregnant solution which must go through electrowinning (cost), and finally through smelting (another cost).

The Hill reporter Sharon Udasin writes that MIT researchers have developed a new solar-powered desalination device that "could last several years and generate water at a rate and price that is less expensive than tap water." The researchers estimated that "if their model was scaled up to the size of a small suitcase, it could produce about 4 to 6 …

This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for …

Plants accumulating more than 1 mg kg −1 of gold are considered as hyperaccumulators; this limit is based on the normal gold concentration in plants of 0.01 mg kg −1 (Sheoran et al., 2013). Plants do not normally accumulate gold due to the low solubility of gold in most soils.

Nanoscale gold particles. Gold has oxidation states between − 1 and + 5, but mainly + 1 and + 3. Adding a reducing agent to reduce Au 3+ or Au + to Au 0 is the usual first step in the synthesis of nanoscale gold particles (AuNPs). In addition, the addition of polymers, surfactants or sulfates can enhance the stable dispersion of the particles formed.
