What is the separation method used in gold mining Answer Wiki User May 06 5 54AM Gold is a kind of metallic ores When mine gold the flotation magnetic separation process is needed if Mar 14 32 In gold mining artisanal miners use different methods depending on the equipment available to them Some of the common artisanal mining includes Concentration Methods This is a mining method that employs the processes that increase the concentration of gold in the ore by selectively removing the lighter materials

Jul 23 32 Traditional surface mining can be classified into two groups on the basis of the method of extraction Mechanical extraction or aqueous extraction The primary differences between these mining methods are the location of the ore body and the mode of mechanical extraction Adapted from Yamatomi and Okubo Hartman and Sharma May 05 32 77 Gold Prospecting Tips How to Find Gold Like a Pro Rare Gold Nuggets May 5 so you are better off using more traditional methods After your ores are crushed into a fine dust then you can use any sort of gravity separation method to capture the gold

Separating gold from sand is very easy The main principle used to separate free gold from other material almost always takes advantage of golds relative weight Very few natural materials come even close to being as heavy as gold The proc The life cycle of mining begins with exploration continues through production and ends with closure and postmining land use New technologies can benefit the mining industry and consumers in all stages of this life cycle This report does not include downstream processing such as smelting of

Another technique commonly used in mineral beneficiation is density separation This can be as simple as panning for gold In a simple panning operation or more complex sluice boxes or jigging tables the heavy mineral the gold stays at the bottom whereas the Separation methods like the ones described above if employed properly should yield a high grade concentrate with a large proportion of gold relative to other materials However this gold still needs to be separated from the other remaining minerals before it can be sold
