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.

Bendigo Mining 1993 to present In the 1980s Bendigo Mining listed on the ASX with ownership of leases along the Deborah line of reef. In 1993, the Company consolidated ownership of the entire Goldfield when it purchased WMC’s interests. A detailed account of the recent history of Bendigo Mining is outlined in the Company History.

Effects of cyanide, in the form of sodium cyanide (NaCN) used at the Williams United and Carshalton projects are examined in the paper.

The Archbold (Chewton) Gold Treatment Works was erected c.1884 by Jeremiah Archbold who operated an assay and metallurgical business specialising in the treatment of gold-bearing ore. The battery, furnaces and Chilean mills which survive on the site suggest that the chlorination process was used to assay pyritic ore. The works subsequently incorporated the cyanide process after its introduction to Victoria in the late 1890s. Upon Jeremiah's death in 1917, the works continued to be run by one of his sons, Herbert. Herbert Archbold went on to become widely known throughout Victoria for his cyaniding expertise. Herbert died in 1966 and the property was bought by his son Harry. When Harry Archbold died in the late 1980s the treatment works was closed and everything left as it was. https://vhd.heritagecouncil.vic.gov.au/places/7899/download-reportNineteen page document.
