"The United Pyrites Company's Works are situated about three quarters of a mile from Spargo Brothers, and are on the northern side of the Marong road, in Pinch-gut Gully. Two processes are followed at these works, viz., the amalgamating process and the treatment by means of chlorine gas. The latter is called the Newbery-Vautin system, and the mode pursued is that laid down by Mr. Cosmo Newbery and Mr Vautin, whose names have been given to the process. Mr. Edwards manages these works. Three reverbatory furnaces are used to roast the pyrites, which is weighed in the truck before being put into the furnaces. At this weighbridge a sample of each lot is kept, and if the yield is not equal to expectation, the works are carefully gone over to see where the fault occurs. Care is taken at the furnace to regulate the heat, otherwise the pyrites might slag instead of roasting evenly right through. An immense revolving furnace (made of boiler iron) was used at these works. It was found to be suitable for treating blanket sand, but was not a success for roasting coarse pyrites. The process of amalgamating by means of Chilian mills is the same in these works as at the Western Works, but the United Works are on a larger scale, and eleven mills are utilised. It is the chlorine gas process which is most interesting here. The gas is made from sulphuric acid, black oxide of manganese, and common salt, and the gas is introduced into huge vats, where it works its way through a filter of pieces of quartz and then through the bed of roasted pyrites lying above. The action of the gas transforms the gold into chloride of gold. This is easily dissolved in water, and in that form is drawn off into huge delf jars, where the use of sulphate of iron precipitates the gold to the bottom. A small battery—eight head of stamps in two boxes—is in use here to crush small consignments of stone sent for trial. Test crushings come from all the Australasian colonies, and even from India. The jars used are manufactured at Epsom, and some of the salt used is also of home manufacture, from the Salt Lakes on the Northern plains. Mr. Edwards took us over a new building in course of erection, and in which the chlorine gas is to be generated in the midst of the pyrites— a still further advancement in the new process. There is some very good machinery in this new building, and the tailings from the ordinary pyrites works will also be treated by this chlorine gas system, which has been found to work well at Mount Morgan, in Queensland. The purest of gold is obtained by this process, the gold passing in solution into a charcoal filter, from which it emerges in the shape of metallic gold. We saw some nice cakes of retorted gold at the works. One of 26oz. was from some New Zealand pyrites (2½ tons), and assayed over 23 carats. There were also cakes of Avoca gold, of silver, and of the tremulous amalgam."

R.M. Serjeant was listed as a mining manager and Joseph Flude as a metallurgist. In 1875 they were both living in Ballarat. The patent number is A.D.1875, 4th March. No 2031. According to the patent the hearth of the furnace is in the form of a cone revolving horizontally. The feed is supplied to the apex of the cone by an archimedian screw. The crown of the furnace comprises a double covering or roof with an intermediate chamber for receiving heated air. The inner covering is pierced to admit of the heated air being brought into contact with the pyrites on the face of the revolving hearth. The discharge of the roasted substance is affected by means of a scraper at the base of the cone. It was claimed that this was a new mode of introducing heated air, and the exclusion of flame during the operation of roasting pyrites. The self-acting charge and discharge of the furnace and the peculiar construction of the hot air chambers, and the use of perforated bricks through which the supply of air is affected were also new.

This model of a mechanical ore roasting and chloridising furnace was invented and patented by Thomas Edwards of the Edwards Pyrites Smelting and Ore Reduction Company. This new type of furnace produced a high standard of sulphur free ore known as ‘sweet roasted’. Edwards used this model for demonstrations in the USA. Of note is the central large vertical cogwheel (externally driven) which drives small vertical cogwheels via angled cogging drives. These in turn drive a horizontal wheel. Each side of the vertical wheel is set on an opposite side to the horizontal wheel of its neighbours, resulting in opposite direction rotation of neighbouring horizontal wheels. Each horizontal wheel turns a rabble (set of vertical iron paddles) within the furnace. These rabbles, each turning in opposite direction to its neighbours, move the roasting ore in a zig-zag path through the furnace. The elongated furnace with its line of rabbles produced a much ‘sweeter’ roasted ore than could be obtained from a typical tank-shaped furnace. In 1924, when the model was donated to the Ballarat School of Mines, Ballarat’s Courier newspaper reported, ‘Apart from its historical and education value, the gift should serve to stimulate the inventive faculties of the students who have to win fame for the school and for themselves in the metallurgical world.’ The furnace model was donated to Ballarat School of Mines and used as an educational prop from 1924. The model relates to the mining industry which is a significant part of Ballarat's history and heritage. Ballarat School of Mines is the oldest Technical School in Australia and is celebrating 150 years in 2020.Metal model of Edwards' Ore Reduction Furnace. The model includes cogwheels, rabbles and other details. Scale is thought to be around 1:20M259ballarat school of mines, edwards, pyrites, ore reducation, edward retallack, mining, model

Historic photo of mining at Specimen Hill. After crushing ore, the sand pyrites remaining could be treated to extract even finer gold. The sand was placed in large brick ovens to be roasted, which freed the sand of arsenic, sulphur etc, with the fumes containing these elements released into the atmosphere via a large chimney. Spargo's Pyrite Company operated from about 1870. It closed when there became a shortage of workers during WW1 and appears to have not restarted after the war. Black and white image, possibly copy.

This specimen was recovered from Mica Schist, Canada. Chalcopyrite is a copper iron sulfide mineral with a chemical composition of CuFeS2. Its name derives from the Greek words for copper (chalco-) and brass (pyrite). It can be found in shades of yellow, green and grey, and, when exposed to acid, it can change to purple, blue, violet and yellow tones. Weathering can cause loss of its metallic luster and its brass-yellow colour. Chalcopyrite forms under various conditions, with the most significant deposits being hydrothermal in their origin. It is known globally as the most important ore of copper for thousands of years, and is thus considered a very important mineral formation. Given its golden appearance, it is often confused for the mineral gold, earning it the popular reputation as 'fool's gold' or 'yellow copper'. However, it can be straightforwardly distinguished from gold; the latter is soft, with higher specific gravity and a yellow streak, whereas chalcopyrite is brittle, easily scratched by a nail, and has a greenish grey streak. Copper was the first metal that was used by people. It was discovered by the Neolithic man about 9,000 years ago and it gradually replaced stone as it was easier to be shaped. In Australia, search for copper began after the European settlement, leading to the discovery of substantial deposits, like the one at the Olympic Dam in South Australia, which is regarded as one of the largest copper deposits in the world. Chalcopyrite has been used for copper since smelting processes began approximately five thousand years ago. Although by no means rare, this the specimen of this mineral can be used to reflect a wider history of industrial uses of copper for a significant portion of human history. 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 solid hand-sized copper iron sulfide mineral of brass yellow, often with an iridescent tarnish, with greenish-black streak and submetallic luster. Chalcopyrite can be formed in several ways, including crystalizing from accessory minerals in igneous rocks, or from magma or within volcano sulfide deposits. Most commonly, chalcopyrite are found in hydrothermal conditions, where it forms in hydrothermal veins. As a member of the tetragonal crystal system, it often takes the shape of tetra-headed crystals, often with striations along the sides of the crystals. #18 Copper pyrites/(chalcopyrite) in/Laurentian Slate/(page 315 of inventory)/page missing from/descriptive catalogue/ Other label: 81 /fool's gold, chalcopyrite, mineral, rock, geology, geological, hydrothermal, neolithic, european settlement, olympic dam, south australia, stone, deposits, specific gravity, greenish grey streak, brittle, mineral gold, metallic luster, cufes2, greek words
