The Borax Method of Gold Extraction for Small-Scale Miners
The borax technique spread to fellow miners and presently around 15,000 SSM in a small area of Luzon, the main island in the northern portion of the Philippines, use this method exclusively. The mineral is inexpensive and easily available, and the miners have found that more gold is recovered through its use, as discussed below.
GOLD RECOVERY BY SMELTING WITH BORAX Smelting

The Borax Method of Gold Extraction for Small-Scale Miners,
01-06-2012· Using the borax method, a total of 23 grams of gold was recovered from the remaining 7 sacks of ore. The miners of Kalinga realized through this demonstration that they could potentially recover as much as three times as much gold by using borax compared to mercury, for less money and no additional effort.
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.

The Borax Method of Gold Extraction for Small-Scale Miners. The Borax Method . Not only did the Benguet SSM introduce the borax method of gold extraction as a tool, they also fine-tuned each step of the process from crushed ore to gold pellet. Their method is as follows: The first step after crushing the ore is milling.

Using Borax Flux to Refine Gold - Manhattan Gold & Silver
07-08-2013· With some borax, heat, and a little know-how, it’s possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
Enhanced Gravity Borax Method for Sustainable gold recovery
Enhanced Gravity Borax Method (GBM) of Sustain a ble Au Ore Processing The Innovation enhances the eco-friendly borax smelting efficiency increasing the consistency and purity of the recovered gold ("Au"), it’s amenability to Portovelo-Zaruma’s low-medium sulfide Au quartz geology, and it’s portability with the use of:

(PDF) Borax as an Alternative Method to Mercury for Gold,
Borax and mercury were shown to recover 22.5 g and 7.2 g of gold respectively. Gold obtained from borax recovery method does not contain any amount of mercury compared to gold obtain from mercury recovery method. This indicates that borax recovery method results in purer gold than mercury recovery method.
