The Mining Process – Waihi Gold The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Gold mining - Wikipedia Romans used hydraulic mining methods, such as hushing and ground sluicing on a large scale to extract gold from extensive alluvial (loose sediment) deposits, such as those at Las Medulas. Mining was under the control of the state but the mines may have been leased to civilian contractors some time later.

Jan 23, 2012· Gold miners too take special care to make the impact of mining for gold as light as possible Reclaiming land to its previous natural state is the final and perhaps most important step to ensuring the process of obtaining gold doesn’t result in permanent damage to the landscape.

9 Step Process for Discovering, Mining & Refining Gold Finding Deposits. The first step is discovering where gold deposits may be. Geologists use special ‘geology’ maps to look for promising areas to explore further. Analysis of Promising Areas. Once some promising areas are identified through their geological characteristics, targets for drill testing are outlined using a variety of techniques, including remote sensing, geophysics and geochemistry (…both air and ground based). Drill Testing/Samples. Next, rock samples are taken through drill testing and analyzed. Geologists and mining engineers use these samples to determine if gold actually exists, the size of the deposit and the quality of gold in the ground beneath. Type of mine. If it’s determined the amount and quality of deposits makes mining worthwhile, engineers will next determine the type of mine that’s needed, any physical obstacles and the impact the mine will have on the surrounding environment. process in mining of gold Gold mining Wikipedia.
