Kajian Teknis Manajemen Stockpile Pada Area Exportable Transit Ore Terhadap Moisture content Bijih Nikel Di PT. Koninis Fajar Mineral Kabupaten Banggai, Provinsi Sulawesi Tengah

Abstract

PT. Koninis Fajar Mineral is a company engaged in nickel mining operating in Banggai Regency. In the nickel
mining process, nickel is not sent directly to the smelter, but nickel is stored first in the stockpile. The nickel
produced must comply with the demand and conditions desired by the smelter, the specifications for the request
for smelter nickel content are Ni 1.8%, Fe 15-40%, moisture content (MC) <35%, and SiO2 <2.5%. This study
focuses on moisture content levels. This study aims to analyze the potential for increased moisture content
levels from various factors in stockpile management activities. The method used is to observe the stockpile
management process from the beginning of nickel being stacked until it is transported. Based on the results of
research and observations made, there are several factors that have the potential to increase the moisture
content of nickel piles. Factors causing an increase in the moisture content in the piles include the condition
of the stockpile floors being unfavorable, not closing the piles when it rains, not optimally stacking the piles,
and unfavorable ditch conditions. Efforts that can be made to maintain nickel quality so that moisture content
does not increase include repairing stockpile floors, covering piles using tarpaulin when it rains, maximizing
stockpile maintenance and supervision, and repairing stockpile area ditches.
