Leaching. [image 145-7-02] Traditional methods viz – ore sieving, washing, etc. are obsolete and uneconomical. Pyro-metallurgy is highly costly and non-viable for low-grade ores. Leaching is the only process to extract metallic content from the low-grade ores. Among leaching methods — Heap leaching is most economical.

Gold Heap Leaching Process Xinhai

Sep 10, 2021 The gold heap leaching process is to crush low-grade gold ore to a certain size, then pile it on a leak-proof bottom mat to spray the cyanide solution from above for getting gold when the solution is infiltrated through the ore layer. Because the investment and production cost of the gold ore heap leaching process is lower than that of the conventional cyanidation method and the process is.

Gold And Silver Leaching By Cyanidation

Apr 18, 2016 Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.
