What is a high grade ore?
It's an ore that doesn't contain a very high proportion of valuable minerals. The term could also be applied to richer ores containing large amounts of undesirable impurities, arsenic for example. Low-grade ores are less valuable than higher-grade 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. The definition of low-grade depends on the resource in question. For copper, low grade ores have less than 1% copper. For gold, an ore having 1% gold by mass would be considered (very) high-grade, as gold is more valuable than copper.
