gold ore tailings concentrate process

Gold Concentrate - ECO - English Wiki

Oct 06, 2020  Gold Concentrate is created by purifying Crushed Gold Ore in one of two different crafting stations. The crafting stations come with different ratios, labor cost and time cost. The process to make Gold Concentrate also gives a byproduct of Wet Tailings which is a pollutant. Gold Concentrate is the last step in the production line for a Gold Bar.

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
