Slagging behaviour of Australian brown coals and
Utilisation of brown coal in slagging gasification technologies requires a detailed assessment of coal ash chemistry in terms of potential slagging behaviour. We investigated the phase compositions of four categories of brown coal ashes and synthetic slags after processing at 900–1100 °C and 1200–1600 °C, respectively, under reducing ...

Australia Coal Usage/Consumption 1960-2024 | MacroTrends
Coal refers to all coal and brown coal, both primary (including hard coal and lignite-brown coal) and derived fuels (including patent fuel, coke oven coke, gas coke, coke oven gas, and blast furnace gas). Peat is also included in this category. Australia coal usage/consumption for 2015 was 62.87%, a 1.71% increase from 2014.
Integrated processing of brown coal and coal sludge (short

Lignite
Lignite, or brown coal, is the lowest-ranked coal, and is placed just above peat in terms of calorific value. It is not a feature of international seaborne coal trades, primarily due to its high water content (which can reach up to 60 per cent) and its lower Btu values (which average 4000–8300 Btu/lb compared with bituminous coals, which ...

Study of Victorian Brown Coal Dewatering by Super …
The difference spectra indicate that the drying of as-received coal at room temperature using a Super Absorbent Polymer (SAP) removes only 44% of moisture compared to oven drying at 105 °C. As the SAP does not completely remove the water from the coal the possibility of explosion due to oxidation of the coal powder is greatly reduced.
The mine | EnergyAustralia
Bringing coal to light. The Latrobe valley is rich in one of Victoria's most important resources: lignite, or brown coal as it's commonly known. This coal is responsible for 85% of the electricity in Victoria, and also supplies electricity to Tasmania and New South Wales. The Yallourn mine is the oldest in Victoria, and Australia's second-largest open cut mine.
20 Shades of Brown Coal
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.
