Wooden model of a cyanide plant. A cyanide plant was used for dissolving gold from finely divided ores by means of dilute solutions of sodium or potassium cyanides. The model has five metal bins, there is some rust on the bins and scorch mark on the wooden base.mining, equipment, cyanide plant, gold cyanidation (also known as the cyanide process or the macarthur-forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. it is the most commonly used leaching process for gold extraction. the ore is comminuted using grinding machinery. depending on the ore, it is sometimes further concentrated by froth flotation or by centrifugal (gravity) concentration. water is added to produce a slurry or pulp. the basic ore slurry can be combined with a solution of sodium cyanide or potassium cyanide, however many operations utilize calcium cyanide, which is more cost effective. to prevent the creation of toxic hydrogen cyanide during processing, slaked lime (calcium hydroxide) or soda (sodium hydroxide) is added to the extracting solution to ensure that the acidity during cyanidation is maintained over ph 10.5 - strongly basic. lead nitrate can improve gold leaching speed and quantity recovered, particularly in processing partially oxidized ores.

Miners' picks were commonly used in the nineteenth and early twentieth century for extracting gold from underground mine tunnels.Found in the Harrietville area. Similar to those used in the nearby Kiewa Valley where prospecting for gold was also an occupation.Formerly KV 071. Handmade - of steel with a wooden handle. It was used to break up rock and ore, making it easier to extract valuable minerals. The pointed end of the pickaxe was used to chip away at rock, while the flat end was used to strike the rock for breaking it apart. This one has a long handle.gold mining, miners' pick

Cast iron mercury bucket, used to hold mercury, potentially in the process of recovering minute pieces of gold mixed in soil and sediments. See research page for description of one process of using mercury to extract gold.gold mines, mining equipment, mercury bucket, miners used mercury in a number of ways to amalgamate gold, with each mill or battery operator having their preferred method depending on the nature of the ore. by the late 1850s the most common way of crushing goldbearing quartz ores or consolidated alluvial cements was in a stamp battery. the battery featured heavy iron stamp heads held in a frame, with each head often weighing up to 500 pounds (226 kg) or more (see msv 1880, page 45) (birrell 2005). stamp heads were lifted and dropped by a rotating overhead cam shaft driven by a steam engine or water wheel. ore was fed into a large cast-iron battery box, mixed with a steady stream of water, and pulverised by the stamp heads. in some batteries, mercury was placed in the base of the boxes to amalgamate with freed gold. the violent agitation of the mercury in the mortar box, however, could cause the mercury to break into myriad tiny globules that were carried away by the water with the tailings, thus losing a certain amount of gold in the process (thompson 1867; ritchie & hooker 1997). the water and sand slurry was splashed by the falling stamps from the box through fine mesh screens and onto inclined wooden tables below the mortar box (figure 2). the tables were covered with copper sheets or plates coated with mercury, which caught and amalgamated with a portion of the gold. the grey putty-like amalgam was periodically scraped off the sheets and retorted in a furnace to collect the gold and recover the mercury for reuse. mercury was inevitably lost from the plates, while poor maintenance resulted in further losses of gold and mercury in the tailings. mercury use and loss from gold mining in 19th century victoria. peter davies1, susan lawrence, and jodi turnbull, department of archaeology and history, la trobe university.

Four male gold miners pose for the camera on their mine site on top of a hill. It appears they are using the underground hard-rock method of mining to extract gold encased in rock.

Gold usually is found as a native metal, but it also forms minerals with tellurium, sulphur, or selenium. The gold-bearing minerals that contain tellurium are called tellurides. Kalgoorlie, Western Australia contains greater than 1500 tonnes of gold.Seventy to seventy-five percent of the deposit occurs as native gold, but a further twenty percent appears as tellurides. What remains is in the form of 'invisible' gold. Extracting gold from telluride minerals, such as calaverite, which contains around forty-two percent gold, has produced approximately three hundred tonnes of gold. Prior to 1896, rocks containing tellurides were not recognised as rich gold ores, and were discarded.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 silvery to pyrite-yellow striated mineral containing tellurium and goldburke museum, beechworth, beechworth museum, geological, geological specimen, mineralogy, telluride, tellurite, gold-bearing, kalgoorlie, tellurium

This photograph depicts mining operations within the Beechworth area, in an unidentified valley where sluicing was utilised as a method for extracting gold from the environment. After gold was discovered in the region in 1851, sluicing became a characteristic of gold mining in the region - "Ovens miners carved intricate networks of races" throughout the region - involved the diversion of water in many channels, or water races, which contained inbuilt 'ripple devices' designed to trap gold for later extraction. By 1871, 900 miles of water races had been cut into the Beechworth Mining District. As suggested by the numerous figures involved in labouring along the water race, sluicing was a source of considerable employment within the region. This image is of important historical significance for its ability to convey information about sluicing and the methods used to find gold in the 1850s, and provides clues as to how sluicing and the widespread construction of water ranges changed the environment of the region. This image is important for current research into the history of the Ovens region in Victoria, which played such a prominent role in the early Australian gold mining industry. Therefore, this image has the capacity to be beneficial for research into society and the motivations of those living and working in this region during this period and therefore, has social significance. The Beechworth Burke Museum has additional images relating to gold sluicing and and the mining activities in the area more generally, which can be analysed and studied alongside images like this one.A black and white rectangular photograph printed on matte photographic paperbeechworth, mining, miners, labour, water race, sluicing

Electro hydraulic dredge Snake Valley 1909. J Mc Bennett, was an engineer back at the main base, at Dawson's dam on the Carngham Road, Between Linton and Snake Valley. These dredges were used for getting gold. The streams of water under high pressure just washed the hills and ground away. This dredge closed down early 1910. 200 H.P. motors were used and 10 in. pumps.Black and white image of three workmen, one beside mining building the other two at dredge pump outlet. Image mounted on dark brown card. Between 1904 and 1911 the Electro Hydraulic Company sought to extract gold in an area north of Linton known as the Hard Hills. By blasting water from high-pressure hoses into the hillsides, soil containing gold was washed out for sluicing. Two gravel pumps in Dawson's Dam pumped the wash through the sluices. Despite considerable investment in expensive equipment, the Company did not have a great deal of success, and the mining operation ceased in 1911.mining, gold, mining equipment, electro hydraulic dredge, dredging, sluicing, dawson's dam, snake valley, miners
