machine separating gold from iron ore

Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold

Selective separation of gold from iron ore samples using

Gold in iron ore samples is separated from iron (major matrix cation), antimony and vanadium using anion exchange resin in (0.2 M) HBr, potassium peroxodisulfate and acetone:water:nitric acid media. The exchangeable anion Cl − of the ion exchanger Dowex 1X 4 is replaced by Br − using (6 M) HBr solution.

Selective separation of gold from iron ore samples using

Dec 01, 2003· The anion exchange resin Dowex 1X 4 Cl − in HCl medium could not be used to separate gold from iron in this kind of samples (iron ores) due to two reasons: the first one is that iron forms in HCl medium, the FeCl 4 − complex which adsorbs on the resin, and the second reason is that AuCl 4 − has stuck in the column and has never eluted. The following eluents have been used but without

Extracting Gold HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
