The aim of this study is to review the literature on the methods of low-rank coal enrichment by using microorganisms and their metabolites. Effective bio-beneficiation technologies for low-rank coals in the future are also suggested throughout this paper. An extensive literature review highlights recent advances in bio-beneficiation technologies for low rank coals. This paper presents the state of the art in the field of the bio-beneficiation technology -carbon leaching with the aid of microorganisms, especially fungi. The knowledge of the low-rank coals leaching is an important step to meet the carbon eco-requirements and improve the economics of mining companies. There are several reasons to investigate microbial activities towards coal. This paper presents the current state of knowledge concerning bioleaching of coal. Thus, in view of the increasing importance of hard coal as a raw material and energy source, it seems hopeful to study the potential of microorganisms to modify the low-rank coal structure.

“…They found 70-80% of total sulfur of coal sample with the size of − 0.074 mm could be removed by using Aspergillus sp. Aytar et al [160] also used Aspergillus sp. in the biological desulfurisation of the coal (Mihaliccik open mine and washing plant, Turkey) and they found that desulfurizing isolate was effective on lignite samples with the size fraction of 0.106-0.038 mm.…”

“…Gravity separation was conducted in MGS and flotation was conducted in flotation cell. The size fraction 0.106-0.038 mm was used as experimental samples based on their previous study [160]. As shown in Table 2, the concentrates obtained from MGS and flotation tests were further desulfurized.…”

“…Sulfur in coal is present mainly in three forms, i.e., organic sulfur, pyritic sulfur, and sulfate sulfur, which the contents of three sulfur forms dominated more than 80% in total content of sulfur types . Pyritic sulfur occurs in coal as mineral matter whereas the organic sulfur is present as an integral part of the coal matrix covalently bounds to its complex structure.…”

The lignite coal collected from Shengli coalfield of Inner Mongolia Autonomous Region in China contains about 5.22% by mass total sulfur with a gross calorific value of 6329 cal g−1. In the present work, the coal sample was subjected to desulfurization by using a new bacterium isolated from the native coal mine site. The native bacterium was identified to be Sinomonas flava XL4 based on the 16S rDNA gene sequence analysis, and reported first time for the capability to remove about 44% of total sulfur from the lignite coal. The influence of various process parameters such as medium pH, incubation time, pulp density, particle size, incubation temperature on sulfur removal from the lignite after S. flava XL4 treatment was investigated, and the experimental results showed that the total sulfur content of lignite coal was reduce to 2.92% under optimum reaction conditions. In addtion, the calorific value of lignite coal after bacterium desulfurization increased from 6329 to 6678 cal g−1, and the ash content was eliminated. © 2015 American Institute of Chemical Engineers Environ Prog, 35: 374–379, 2016
