25.2 Extracting ores | Mining of mineral resources | Siyavula
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.

How the Gold Business Operates
Gold mines produce rough gold, called a dore bar. These bars are typically about 80 percent pure gold. The gold is then sent to a refinery, where it is refined into gold of different forms and purity.

How is Gold Made
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.

How to Make Flux for Gold Refining
Refining gold from ore or concentrates is done during the smelting process. During this process, flux is used to dissolve contaminates such as metal oxides from the gold. The flux is added to a crucible with the gold that is then melted in a furnace. You can make flux for gold refining by first obtaining all of the

Gold
The processing of gold ore involves crushing, treatment with chemicals, melting (smelting) and further purification. It is then poured into moulds where it cools and hardens as gold bars called ''bullion'', which make the gold easy to stack and transport. The first stage of processing gold ore is crushing.

Gold mining
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.

Cyanide Leaching Of Gold
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.
