Processing, smelting and refining gold | World Gold Council

For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining

Ores and Minerals - Introduction, Extraction

We get minerals and ores in abundance in the earth’s crust. Some ores have been proven themselves a great resource for mankind. Such as iron obtained from ore of iron (Hematite) built the foundation of industrial revolution. Out of total naturally occurring elements 70% are metals. Metals occur in nature in free as well as in combined states.

Ore Refining - an overview | ScienceDirect Topics

In the metal refining of ores, the metal is solubilized in an aqueous solution. The optical control of metal refining requires quick, accurate analysis of the major chemical species present in solution. Raman spectroscopy and resonance Raman are used to identify the amine complexes of Co, Ni, and Cu species, as well as ammonia sulfate and sulfamate, present in these industrial solutions.
