    2013-8-7 · 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.gold ore processing by using borax Pixis Mining ,The mercuryfree gold extraction method uses borax in the process of gold smelting. Borax is used in the smelting process because it lowers the melting point of gold and other metals. In this method, the mining of goldbearing ore, the grinding of the mined material and the concentrating from sluicing are the same as in the amalgamation method

  • Mercury-Free Gold Extraction Using Borax for Small

    Abstract. Small-scale gold mining is the largest anthropogenic contributor of mercury pollution on planet Earth. The miners grind gold ore together with mercury in order to recover the fine gold grains. The gold amalgam is burned whereby the mercury evaporates and gold is left behind. This processing extracts only a fraction of the gold in the oreMercury-Free Gold Extraction Using Borax for Small ,2014-6-19 · The mercury-free gold extraction using borax has successfully been tested on a variety of gold ores in Philippines, Indonesia, Tanzania and Bolivia. Recently a successful gold extraction using the method in Zimbabwe was carried out (Stephen Boese-O’Reily personal communication). In the Philippines a Danish-funded two year Figure 2.
