Extraction of Gold using the Borax Process. The borax process is also an environmentally-friendly method of extracting gold. Here the gold-bearing rock material is placed in a melting crucible and then borax (sodium borate) is added. The borax sinks the melting point of the ore mixture and makes the molten mass more fluid.

Therefore we could not o btain a gold concentrate. Amalgamation works fine on the Mt Muro ore. Gold is often enclosed in iron sulphides. If that gold shall be extracted either using amalgamation or borax the ore has to be roasted. Without visible gold the mercury -free gold extract ion method using borax does not work properly.

The random selection was used to compensate for the heterogeneity of gold content in the ore. The Kalinga miners processed a sack with their usual amalgamation technique. They recovered 1.2 grams of gold. A second sack was then processed using borax. Recovery jumped to 3.5 grams of gold. This process was repeated.
In some cases the gold in the ore is extremely fine sized, and using mercury to capture it makes sense. This is also true for operators processing large quantities of hard rock material. I've done up a web page on using Mercury to capture fine gold and you can view it here. (link to page)
Nov 27, 2012· Even gold miners who still use mercury to separate gold from ore use borax at the end of the process to make gold shiny, said Budi. Borax reduces the melting point of metals and minerals allowing small-scale miners -- often called artisanal miners -- to extract and smelt their gold.
In Benguet province, a group of miners have been using the mercury-free gravity-borax method (GBM) for gold extraction for decades. This method basically requires the same equipment as the amalgamation methods. However, after the rod milling, an ore concentrate holding the heavy minerals is produced by using a launder (gold sluice) and a gold washing pan.
