Sulphide Minerals in Limestone: Trap rock of Buton Asphalt (Asbuton) on Block Kabungka Mine C PT Wikaya Karya Bitumen, Buton Regency, South East Sulawesi

EasyChair Preprint 4157

Abstract

We present data to analysis presence the sulphide mineral from three sample from, two sample limestone trap rocks with low grade asphalt and one sample asbuton rock. Sulphide minerals found from all three samples were Pyrite (FeS2), Chalcopyrite (CuFeS2), Bornite (Cu3FeS4), and Covellite (CuS). There were no traces of hydrothermal solusion such as altered rock or quartz veins, but the composition of the analized sulphide minerals had similarities to the sulphide mineral composition in porphyry type andesite rocks from Central Lombok. The presence of sulphide minerals in asbuton trap rocks has the potential to produce pollution in the form of acid mine drainage (AMD), so it needs proper treatment so that water pollution does not occur.

Keyphrases: Limestone, asbuton, sulphide
