Gold Processing Methods & Gold Ore Extraction


Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...

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

Gold Mining | Gold Prospecting | U.S. Gold Bureau


While gold sourcing is often referred to simply as "mining," mining is, in fact, just one piece of the production puzzle. The process of obtaining gold is actually multi-faceted and can be more or less summed up in four steps: prospecting, mining, extracting and refining. In this blog post, we'll explore the initial phases of prospecting and mining.
