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.

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.

Image of Cocks Pioneer Gold & Tin Mines NL directors with Mrs Molly Moline and children, Dorothy and Geoff. Taken at Sherwood - the mine manager's residence. (1914) Cocks Pioneer Electric Gold & Tin Mine Company was formed in 1899. The company's first power station, located at the eastern end of the valley began operating with its 340 Kilowatt steam-powered generator. By 1909, from 2,500,000 cubic yards worked, reported recovery was 17,284 ounces of gold and 224 tons of tin ore. By 1909, Cocks Pioneer’s power plant had become inadequate and uneconomical. The barge was floated downstream about a mile, but lost time caused the operations to cease. Following testing, a new mine was established by diverting Reid's Creek at a cost of £25 000. Settling dams were built, one of which held 1,935,900 cubic feet. Sold earth banks, built against a wall of stringy bark saplings constructed and laced with vertical props, were built. In 1914, the company was reformed as Cock’s Pioneer Gold and Tin Mines NL, another power station was constructed at the western end of the township, near the junction of Clear and Reid's Creeks. From 6,800,000 cubic yards of material processed, the returns were 64,397 ounces of gold and 855 ton of tin. Cocks Pioneer mine then moved the barge downs stream and continued sluicing. In 1929 Cocks Pioneer Electric Gold and Tin Mining Company ceased operations due to a drop in values. Cock’s Pioneer Gold and Tin Mines NL carried on large-scale hydraulic sluicing operations until 1941.
