What is a low grade oreYahoo Answers

Oct 03, 2021 The opposite would be a highgrade ore, which contains a lot of the mineral or metal that you want to extract. Lowgrade ores are less valuable than highergrade ones. Also, recovery rates for low grade ores tend to be lower than for high grade ores that is, a lower percentage of the total amount of metal in the ore is extracted successfully.
