Gold extraction

The solubility of gold in a water and cyanide solution was discovered in 1783 by Carl Wilhelm Scheele, but it was not until the late 19th century, that an industrial process was developed.The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore.The gold could not be extracted frompound with any

What Does Gold Ore Look Like? Sciencing

4/25/2017· A common misunderstanding about the appearance of gold ore is the idea that all gold ore contains visible pieces of shiny gold. While this is sometimes the case, spotting gold within gold ore rocks is occasionally impossible too. A jewelers loupe can help you distinguish flecks of gold within gold bearing ore bodies.
