Metals Gold Borax

In gold refinement, Dehybor ® anhydrous borax is used in flux formulations to dissolve metal oxides and as a flux in gold assaying. The addition of Dehybor to the smelt is generally 10-50% of total smelt weight, depending on the process. The borax contribution to flux composition can be up to 60% of total flux weight but is typically around 30

Using Borax Flux to Refine Gold Manhattan Gold & Silver

Aug 07, 2013· As the process continues, the borax causes the other minerals to oxidize and breakdown even further. Gold is unaffected by this reaction and sinks to the bottom of the mixture, intact. The mixture of oxidized impurities and flux becomes slag, which is scraped away to reveal the pure gold at the bottom of the crucible.

Borax method Wikipedia

The borax method is a technique of artisanal gold mining, which uses borax as a flux to purify gold concentrates. By using borax, no mercury flour is produced, hence gold recovery increases.

Gold Recovery : 8 Steps (with Pictures) Instructables

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.

How Gold Is Refined: A Step-By-Step Guide Pease Curren

The refiner takes either the sample or the entire portion of gold and mixes it in a crucible with a flux (soda or borax) and lead or silver. The flux lowers the melting temperature of gold, making the process somewhat easier to complete, and the lead helps to collect the pure gold from the alloy.

A Poor Man's Method of Smelting Gold Sciencing

Pour off the slag into a heat resistant container. The liquid will be too thick to pour once it is cold. Add in some borax to thin out the liquid. When the liquid cools, chip off the glass — which will have floated to the top during the cooling process — and there is your gold, smelted to perfection.
