Smelting and Roasting Ores to recover gold, silver and other metals
The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.

Method of Gold Extraction using Borax -Small Scale Miners No Mercury
Gravity Borax Method GBM Mercury Free Gold Recovery. The Gravity-Borax Method GBM is still unknown to most Artisanal and small-scale gold miners (ASGMs) worldwide as most still use mercury to extract gold. “Whole-ore amalgamation ” is a technique that requires the use of 10–25 g of mercury to produce 1 g of gold.

Artisanal and Small-Scale Gold Mining Without Mercury | US EPA
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 miners, and high gold recoveries.

Philippines: Child Labor and Gold Mining | Pulitzer Center
A little boy, perhaps about five-years-old carries a half-filled ore sack up a hillside at the Panique mine. An estimated 18,000 children work in small-scale mines in the Philippines. The country ranks 18th in gold production worldwide and the steady increase in global gold prices have had a corresponding impact on the number of child laborers.

The Mercury Problem in Artisanal and Small‐Scale Gold Mining
Mercury‐dependent artisanal and small‐scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with a torch or over a stove—to distill the mercury and isolate the gold.

Heavy Metals in the Soils of Placer Small-Scale Gold Mining Sites in
Background: Artisanal and small-scale mining activities are widely practiced globally. Concentrations of heavy metals associated with gold, such as copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb) can increase in the environment as a result of mining activities, leading to environmental pollution and pose toxicity risks to humans and animals.
