This is a colour image of a model of a molecule of ethanol, CH₃CH₂OH. In this model, atoms are represented by coloured spheres held together by grey rods that represent covalent bonds. The molecule contains two carbon atoms (the black spheres), one oxygen atom (the red sphere) and six hydrogen atoms (the grey-white spheres).

This fact sheet describes oxyfuel combustion, the technology that burns fuel in almost pure oxygen. Because this makes it easier to capture carbon dioxide from flue gas, there is the potential to achieve near-zero carbon dioxide emissions from the production of coal-fired electricity. A diagram illustrating this process ...

• TLF-IDM008848

Find out how gas-fired power stations work. This fact sheet describes the generation of electricity in gas-fired power stations, which typically produce 50 per cent less carbon dioxide than conventional coal-fired power plants. Information is provided about the Daandine Power Station located west of Brisbane, which uses ...

This interactive activity allows students to explore the processes involved in the mining and processing of copper ore and the production of copper. Students initially put the processes in the correct sequence and then select each stage to animate it and access relevant information. The smelting stage includes an activity ...

Find out what minerals can be found in beach sands and why they are important to us. This is a PowerPoint presentation about sand minerals and the products derived from them. It deals with the origin and deposition of the mineral deposits, the properties of the minerals zircon, rutile and ilmenite and their uses as well ...

• TLF-IDM008847

This fact sheet provides information about how coal seam gas or methane is extracted and used as an energy source. It describes several coal seam gas operations in the Bowen and Surat Basins in Queensland. Several photographs and a map of projects in the Surat Basin are also included.

• TLF-IDM008864

Find out how a coal-fired power station makes electricity. This animated video in 11 parts shows the components and processes in a coal-fired power station. The narration explains what happens at each stage. Most of the statistical information and examples relate to locations in Queensland.

• TLF-IDM008840

This is an information sheet containing a student activity simulating geological sequestration of carbon dioxide as well as background information for teachers. The background information describes sequestration in geologic formations, including oil and gas reservoirs, unmineable coal seams and deep saline reservoirs. The ...

This is a 36 cm x 55 cm hand-coloured lithograph of a pair of thylacines (‘Thylacinus cynocephalus’), commonly called Tasmanian tigers, against a background of small bushes and an open plain.

• TLF-IDR6881

This is a colour photograph of a 'Zygomaturus tasmanicus' fossil skeleton. The skeleton is a museum specimen and has been braced with metal rods. It is displayed in a standing posture.
