Gold mining is a global business with operations on every continent except Antarctica and gold is extracted from mines of widely varying types and scale Mines and gold mining operations have become increasingly geographically diverse far removed from the concentrated supply of four decades or so ago when the vast majority of the world’s

In addition to surveying mining geologists use portable XRF analyzers to perform ore grade control to figure out where the most profitable ore bodies are in terms of location and mineral concentration variability Ore deposits are inconsistent in nature having high concentrations of metals in one area but much lower concentrations in others

Mineral concentration has been known since ancient times The first description of many processes for concentration of minerals the processes were of course primitive was given by Agricola 1556 The development of mineral concentration in Russia was associated with the extraction of gold from ores

Peru privatized and deregulated its traditionally stateowned mining sector Transnational mining companies attracted by Peru’s rich mineral endowment quickly began to invest The largest investmentand what is still Peru’s largest gold minewas the Yanacocha Mine in Cajamarca USbased Newmont Mining Corporation operates the mine

A lower grade gold ore would contain something like 5 grams of gold per ton of earth 5 parts per million So gold ore needs to be concentrated by about 1000 times its average concentration to become viable High concentrations of gold were discovered in South Africa in the 1880’s
