Step 7 Processing on-site Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing. Step 8 Refining off-site

2020-5-30Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the worlds gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in ...

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.

Soil sampling is a basic technique of mineral exploration. Cheaper than drilling, sampling can be used to quickly establish the existence and extent of hoped for mineralisation.. Initial geophysical and other remote sensing methods are used to target a geological structure which may contain mineralisation.
