The Borax Method is a technique of artisanal gold mining, with its basis in the principle that borax reduces the melting point of all minerals, including precious metals like gold. The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases ...
· Updated smallscale gold mining operations data: Majority of the activities of the ASGM sector in the Philippines remain undocumented due to the absence of gold production data at the level of the miners, illicit financial flows in gold trading, insufficient government budget, and poor implementation of and compliance to policies, among others.
