Alternate uses for brown coal - Earth Resources Brown coal is not currently widely traded due to the challenges in exporting the raw resource. 'Run of mine' brown coal from Victoria's reserves in the Latrobe Valley is reactive and has a high moisture content, which makes it unsafe and uneconomic to export without processing (drying and stabilising).

A process of manufacturing briquettes from brown coal includes drying brown coal, which is preferably in fine granular form. The dried brown coal is then heated at a first rate up to a temperature in a range of from about 300° to about 320° C. The brown coal is subsequently heated at a second rate, which is less than the first rate, to a ...

The ANLEC R&D Brown Coal research node is managed through the Australian Carbon Innovation (ACI), where a comprehensive list of brown coal related activities may be viewed. The Victorian Government has established the ACI to foster and support world class research and development (R&D) to reduce greenhouse gas emissions from brown coal utilisation.
Coal Processing Steps: The first step of the coal preparation process involves feeding the ore through a size reduction stage which is typically a roll crusher or mineral sizer and then a …
Nemec 151 decomposed the brown coal in a water steam plasma generated in an arc discharge of 60 kW power. The mass flow of coal amounted 0.42 - 4.2 kglh. The gas reaction product contained: H 60-83, CO 28-16 and CO 12-0 vol. %. Stuart, Munz and Gauvin 161 designed a reactor in which peat was injected into water steam plasma.
Mining and advanced processing of brown coal is to enforce utilization of national energy resources. Brinev deposit • After detailed exploration carried out in 1996-2001 an …
Brown coal, stored under the relative humidity of 74% for 7 days, lose water in the amount of about 34% by mass. Brown coal based fertilizers, stored under the relative humidity of 74% for 7 days, lose water in the amounts of 13–16% by mass. It was found that brown coal and brown coal based fertilizers underwent a natural drying process.

Brown coal is produced and utilised almost exclusively in Victorian mines and power stations. The Loy Yang Complex and Yallourn W power stations are located in the Latrobe Valley within the Gippsland Region of Victoria, the coal is mined from near-surface deposits in the Yallourn-Morwell and Loy Yang coalfields.
In 2013-14, Australia produced 57.8 million tonnes of brown coal. This is about 10 per cent of the global output. The Australian output of brown coal has been consistent and, most likely, will remain consistent, as it is produced entirely for the local market. The Australian resources of brown coal are estimated at over 400 billion tonnes.
Many brown coals of lighter colour have a fibrous structure in which roots and other plant matter are still recognizable, indicating little coalification beyond peat. Brown coals can be distinguished from higher-ranked coals by observing their behaviour in dilute nitric acid or boiling potassium hydroxide solution.

The Australian resources of brown coal are estimated at over 400 billion tonnes. The current economic downturn and low prices on thermal and metallurgical coal, as well as low oil prices, may delay the development of some lignite projects and, most importantly, the development of lignite processing technologies.
