Sphalerite or sphaelerite is named from the Greek word for 'treacherous' or 'deceiver' as specimens can vary widely in appearance, making them hard to visually identify. It is a zinc sulfide with the chemical composition (Zn,Fe)S, the most important ore of zinc. Specimens of sphalerite can contain iron as a substitute for up to 25% of the usual zinc present, as well as trace elements of gallium, cadmium, geranium and indium. Small amounts of arsenic and manganese may also be detected. Sphalerite is found in igneous, sedimentary and metamorphic rocks. It forms when carbonate rock encounters acidic, zinc-bearing fluid. It often forms in veins or in fissures of the existing rock, with colours and crystal shapes dependent on the composition of the the combining elements. It forms isometric crystal shapes including cubes, tetrahedrons, octahedrons, dodecahedrons. This specimen was collected in approximately 1852, in Broken Hill, NSW, as an adjunct to the Geological Survey of Victoria. It was donated to the Museum in 1868. Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century. The identification of sites containing valuable commodities such as gold, iron ore and gemstones in a locality had the potential to shape the development and history of communities and industries in the area. The discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole.The specimen is significant as an examples of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.A pipe-shaped specimen of sulfide-mineral zinc ore displaying patches of black, brown, beige and gold colouring.

This specimen was recovered from Broken Hill, NSW. It was given the name Mangan Hedenbergite in 1819 by Jöns Jakob Berzelius in honor of Mr. Anders Ludvig of Hedenberg who was the first to define hedenbergite as a mineral. Hedenbergite, belongs in the pyroxene group having a monoclinic crystal system. The mineral is extremely rarely found as a pure substance. Mangan Hedenbergite is a manganese bearing variety of Hedenbergite. Manganese is the world’s fourth most used mineral after iron, aluminium, and copper primarily because it has no satisfactory substitute in its major applications. Globally, the steel industry is the primary user of manganese metal, utilizing it as an alloy to enhance the strength and workability of steel and in the manufacture of tin cans. Manganese is a key component of certain widely used aluminium alloys and, in oxide form, dry cell batteries used in electric vehicles. These batteries are in high demand. Another potential use for manganese may as an additive to help coat and protect a car’s engine. Manganese is also used for non-metallurgical purposes such as plant fertilizers, animal feed, and colorants for bricks. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A hand-sized mineral specimen in shades of silver and blackmanganese, open cut mine, manganese ore processing, bell bay, tasmania, northern territory, steel industry, zinc-carbon batteries, alkaline batteries, tin cans

A wooden miner's cradle with metal sieve used to separate gold or other heavy minerals from soil and water. Washdirt and water were tipped into the sieve at the top while the cradle was rocked. The oscillating motion washed away sand and fine particles, leaving the gold trapped behind ridges across the bottom. Large rocks and gravel caught by the sieve were discarded by hand. The metal sieve is slightly damaged.gold minning, gold washing cradle

BHS CollectionNine typed pages of notes on a preliminary draft for a brochure on the Bendigo Diggings. First part is the objective which is to preserve the mining history and to have exhibits in the places they were used, e.g. quartz mining machinery exhibited in a quartz mining area, not on an alluvial field. Part B is historical notes on the area. Part C is the Site - Victoria Hill area. Part D is Stage One which consists of carpark area, technological museum, restaurant, mineral haulage line, picnic ground, earthworks and planting over the area. Part E is Stage Two which will consist of the open-air exhibits, in the area surrounded by the mineral haulage line, and the Central Nell Gwynne mine on the west side of the site. Part F is Stage Three which will consist of the winery, the steam tram track, the lake, the wildlife sanctuary and various buildings associated with gold mining.
