  • How Is Gold Graded? | BullionByPost

    The term gold grade is commonly confused with gold purity, with the two meaning something quite different 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 Gold purity measures the amount of natural gold mixed with other metals in finished gold products or, more strictly, gold alloy products0–05 g/t gold is low grade; 05–15 g/t gold is average grade; Over 15 g/t gold is high grade Underground: 0–50 g/t gold is low grade; 50–80 g/t gold is average grade; Over 80 g/t gold is high grade; Gold measured in ounces per tonne is “bonanza” grade Silver Open pit: 0–30 g/t silver is low gradeWhat Is High Grade? independentspeculatorThe former involves smelting of the ore or concentrate at high temperatures, while the latter involves leaching the ore or concentrate at relatively low temperatures, including ambient These two broad processing paths may be broken down further into the following routes, as shown in Fig 5, for copper and nickel ores:Low grade ores – Smelt, leach or concentrate?
