Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves.

What is high grade gold ore?

Gold grade is a term used in gold mining, and should be used as a measure of the quality of gold ore – that is the raw material obtained from mining. High-grade gold ore contains more gold per tonne; this means that more gold is obtained from every tonne mined. This greatly increases the profitability of a mine.

What is a good gold ore grade?
