Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of low-grade, oxide deposits.Gold CIP Processing,Gold CIP Plant,Gold CIP Production .CIP process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with high grade silver as well. Generally, the proportion of gold and silver should not exceed 1:5.

Processing, smelting and refining gold | World Gold Council

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.Ore processing – Waihi GoldAt the processing plant, gold and silver are extracted from the ore. The processing plant alternates between treating ore from the Martha Mine open pit and from the Favona underground mine.
