An increase in gold and copper recovery was found in the <20 μm fraction to a high level of statistical significance. For the >20 and <38 μm size range, the copper recovery increased to a high level of significance, whereas the increase in gold recovery in this fraction was to a lower statistical significance.

Generally, the rates of copper are about 3 to 6 pounds per acre (1.5 to 3 kg. per .5 hectare), but this is really dependent on the soil type and plants grown. Copper sulfate and copper oxide are the most common fertilizers for increasing copper levels. Copper chelate can also be used at about one-quarter of the recommended rate.
