The clear solution drawn off from an agitator is run to two settling vats 16 ft. 6 in. in diameter by 4 ft. deep. The solution stands in settlers until any cloudiness has settled. It is then run through a sand filter and then to the zinc boxes. An 80 per cent gold recovery was made by the method of treatment described.
Notes on the Ore Reserve estimate: Ore Reserves are a subset of Mineral Resources. Ore Reserves are estimated using a gold price of A$1900/ounce. Ore Reserves are estimated using a cut-off grades between 0.3g/t and 0.4g/t Au. The above data has been rounded to the nearest 100,000 tonnes, 0.1 g/t gold grade and 1,000 ounces.

Initially, bottle cyanidation tests are conducted on 200- to 500-gram charges of ground ore to determine the degree of gold extraction and reagent consumption. If the gold content of the ore is leachable at a relatively coarse grind, column percolation tests are made on ore crushed to various sizes, ranging from minus 2- to minus ¼-inch feed.
Sulfide sulfur oxidation through the autoclave is typically of the order of 90—92%. Residual S exiting the autoclave is targeted at less than 0.2%. Values greater than 0.25% S" typically result in poorer gold recoveries in the C1L circuit. Free-acid levels in the autoclave discharge are a function of S2 and CO2- in the autoclave feed, but ...

Project Description. The Mercur Gold Project consists of a 2700 tonne (3000 ton) per day carbon-in-leach (CIL) gold plant. In addition to the process facilities, the project incorporated the following: a) Upgrading and modifying of the existing 11 km (7 miles) of Tooele County road, from State Highway 73 to the project area.
Two tests were made in the laboratory of which I have a note: one for 10 minutes and one for 15 minutes. The ore contained $6.50 gold and 2% copper; 12% of this sample would remain on a 60-mesh screen. The first one gave a concentrate containing $22.70, 9.4% copper, and 18% insoluble, with an extraction of 51% of the gold and …
