Gold Mine Construction and Operation - gototps

19-12-2018  Constructing a Gold Mine: Variables to Consider The type of mine dictates the tactics that a company can use to extract the minerals. Different processes are required when comparing an open pit (surface) mine to an underground mine. Some mines are constructed so that both the pit method and underground method may be used.

Lifecycle of Gold Mine: Mine Construction

It is important to note that there are other ways to mine for gold, such as dredging, and some mines are even a hybrid open pit/underground mine. While gaining access to the minerals can be considered a construction phase undertaking, this is a bit of a grey area because some of this overburden that is removed may actually be processed for minerals.

The Mining Process – Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called ‘beneficiation.’ Milling is one of the most costly parts of
