Mar 13 2018 · How to Melt Gold Out of Rocks The process of extracting gold from ore is a multistep one and historically it has involved the use of some dangerous chemicals including cyanide and mercury Cuttingedge extraction techniques have eliminated the need for these chemicals and made the process much safer Its still too dangerous to try at

Bromine acts more energetically than chlorine and has also been employed in the extraction The recovery of the gold is effected similarly and the bromine is then liberated by the action of chlorine but it is impossible to prevent loss of bromine Cyanideprocess The extraction of gold by the cyanidemethod is of great technical importance

Hand Crushing and Processing Rich Ores Here is a discussion of the procedures to crush Quartz or other minerals and extract the gold from these rich ores Sometimes heavyduty chisels can also come in handy in this part of the process as one breaks down large chunks into fist sized and smaller pieces that can be more easily handled

Aug 06 2016 · The simplest method to extract gold from rocks is following 1 Get a larger hammer or mortar and pestle 2 Get the gold pan 3 With the hammer crush the rock down to the powder 4 Separate the gold from other minerals by using the gold pan Mo

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
