This International Standard specifies a flame atomic absorption spectrometric method for the determination of the aluminium, copper, lead and zinc contents of manganese ores and concentrates. The method is applicable to a concentration range of 0,1 to 4,0 % (m/m) of aluminium; 0,005 to 1,0 % (m/m) of copper; 0,005 to 1,0 % (m/m) of lead; 0,005 to 0,25 % (m/m) of zinc. This International Standard should be read in conjunction with ISO 4297.
