The recovery of the minus 75 ?m (200 mesh) fraction was 58%. /// a) Either no sets were received using digestion by two acids (hydrochloric and nitric acids) or the sets using digestion by two acids were declared method outliers based on statistical tests. / b) The mean is based mainly on data from samples of 1 to 2 grams ignited for 1 to 2 hours at 900 to 1050°C. / c) The mean is based mainly on data derived from various complete digestion methods.
