Abstract

Warukin Formation has a lot potential as a coal-bearing formation in Rantau South Kalimantan, Indonesia.
However, potential harmful to the environment posed by trace element needs to be examined. Because when the
amount is above a specified threshold, it will be very dangerous because of its toxicity. Trace element in coal is
dependent upon the chemical nature of the elements that are contained inside the coal.Trace element can be
associated with elements of coal or mineral matter there. With the increasing emphasis on the trace element now
routinely performed. The study was to determine the source and the impact caused by trace element. Eight examples
of the coal seam have been taken for analysis: AAS, XRF and coal petrographic. Based on coal petrographic
analysis, the average mineral matter composition was 2.4% consists of mineral oxide, pyrite and clay. The total
amount of sulfur in the seam 0,14 %, it’s much lowest. Most elements are positively correlated with the existing
content in the ash for trace element that is: Cl, As, B,Hg, Se and F. The concentration of trace elements that are in
the world average coal, thus indicating the absence of low-level hazard or danger to the environment.
