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.
Lead and zinc ores (usually sphalerite, ZnS) often occur together and may also contain silver, copper and gold. The ore has first to be separated from clays and other silicates ('gangue') after which the lead ore and the zinc ore are separated. The process used is froth flotation, a succession of stages each delivering a greater concentration ...

Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydro-chloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from low-grade ore.

of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis. Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals.
Oct 24, 2018· Gold mining underground and the extraction of gold A gold bar being cast Even though to free the gold particles from their solid mantle in the ore extracted underground. For this process the gold-bearing rock is crushed to sand and dust.
Extraction of Silver by cyanide process and its uses. Silver also occurs both in combined state as well as in free state. The important ores of silver are: Argentite (Ag 2 S), Copper silver glance, Horn silver, Ruby silver. The silver ores are found along with gold ores in some parts of India.
Extraction of Gold using the Borax Process. The borax process is also an environmentally-friendly method of extracting gold. Here the gold-bearing rock material is placed in a melting crucible and then borax (sodium borate) is added. The borax sinks the melting point of the ore mixture and makes the molten mass more fluid.

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.
Once extracted, the gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp. Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore. Mining
This process is necessary because platinum, even in ore, needs to be removed from other substances. Platinum is an incredibly rare metal that is mined and extracted in a variety of different ways depending on the technological sophistication of the miners attempting to extract it.
Gold Separation Process In The Mining The process of separation of concentrate mineral ore in a Gold Mining in general should be done in a gradual manner, and the function of the separation process is to separate gold ore minerals from mineral impurities or mineral carrier.
First, crush the ore. Then, a chemical process is generally used to extract the metal. In gold's case, I believe it's a leeching process involving an arsenic compound. The solution is essentially sprayed on a big pile of crushed ore, with a rubber mat underneath to catch the runoff.
