This study aims to correlate fixed carbon content using proximate analysis and calorific
value analysis of the South Sulawesi Mallawa Formation coal. The study was conducted at …

Coal petrography extraction is crucial for the accurate analysis of coal reaction
characteristics in coal gasification, coal coking, and metal smelting. Nevertheless, automatic …

One of the main parameters that determine the processing and utilization of coal mining is
the quality of the coal. This research was conducted to determine the quality of coal based …

Abstract The Mallawa Coal Formation in general, has a high sulfur content even though the
calorific value is quite high. Deposition environment will affect the sulfur content in coal. This …

Coal that is deposited in the same depositional environment, age, and formation will usually
have the same characteristics. However, the influence of geological conditions in an area …
