The gold in the veins can be in many different forms like nuggets or sheets, or in gold compounds. In recovering gold from vein ore, the ore is first crushed in rod or ball mills. In this process the ore is crushed to a powdery substance from which the gold can be extracted by gravity separation.

Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram: In this chapter we will look at each of the steps in more detail.

Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the Merrill-Crowe zinc precipitation process and the other is the adsorption of the gold onto activated carbon.

Gold mining is the extraction of gold resources by mining.Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning.However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation.

The process of placer mining is the process that is used to find the gold that has been eroded from the lode. Very generally speaking, placer mining involves sifting through gravel to separate the pieces of gold. Placer mining can be done by a single prospector with a gold pan. The process of lode, or hard rock, mining, on the other hand, is

The second method of refining gold involves the use of chemicals. Strong acids are used to dissolve the impurities in the gold ore and afterwards, are neutralized and washed away, taking the impurities with them. The resulting product is a muddy substance that is almost pure gold (99.999% or 24K).
