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.

The Jubilee Mine at Scarsdale was started by Thomas Greenwood of Italian Gully.Jubilee Company Quartz Gold Mine has one of the most comprehensive range of quartz mining foundations in the State. The brick and concrete foundations cover pumping, winding and crushing operations, as well as cyaniding of mine tailings. The machinery foundations are the remnants of large scale quartz mining operations carried on at the site between 1899 to 1912. During this time the mine produced over 125,000 ounces of gold and was the district's most important gold mine.

Ordered by Langwill Bros., & Davies Ltd Melbourne Used for saw milling, dam constructions and log haulingFoden Traction Engine This engine is a compound traction engine built by Foden Ltd of Sandbach England in 1914 – builders number 4525. This was ordered by Langwill Bros and Davies Ltd of Melbourne and was used by Mr F Orr on his farm at Bullarto South Victoria. On the farm it was used for many agricultural purposes and was used at times as a stationary engine to run a wooden thrashing machine. The unit was last used on the farm in 1947 and put aside on the farm with a “museum” of other old agricultural tractors and machinery. Mr Orr gave us the engine as an exhibit for the Menzies Creek Museum of Puffing Billy in the 1960s. At that stage he was an elderly gentleman of 97 years and maintained a great interest in his farm which had been in his family’s hands for three generations at that stage. His grandfather had cut the farm from the bush. The traction engine in its youth was used to go around other farms in the district and went as far away as the Wimmera and Mallee farms thrashing crops of wheat, barley and oats. It towed the wooden thrashing machine behind it on its trips to these farms on hire to the farmers. Foden Compound Traction Engine Built by Foden Ltd., Sandback, England in 1914 to the order of Langwill Bros., & Davies Ltd., Melbourne, it was used on a farm for sawmilling, dam constructions and log hauling.
