  • Extracting Gold HowStuffWorks

    Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

  • Method of Gold Extraction using Borax -Small Scale

    2020-6-25  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.

But the amount of gold in the earth is extremely small, so that mining is not really worthwhile. Generally there are two types of gold: primary gold (“mountain gold” from mines) and secondary gold (“stream gold” , “nuggets”). Above all the extraction of primary gold is associated with considerable effort. There are various methods to free...
