Al, Zn, Pb, Mn, Na, K, S (in decreasing order of occurrence) indicating that these particles containing a few of the above elements are homogeneous in nature. The larger particles show wide variation in intensity ratios and hence variation in the chemical composition of the grains from point to point. Thus the approximate size of the zinc-containing and other homogeneous grains in the retort residue is in the range of 0.5 to 8.0 µm.
