Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to

Dump leaching is an industrial process to extract precious metals and copper from ores. Dump leaching is similar to heap leaching, however in the case of dump leaching ore is taken directly from the mine and stacked on the leach pad without crushing where, in the case of gold and silver, the dump is irrigated with a dilute cyanide solution that percolates through the ore to dissolve gold and

Cyanidation tests by bottle agitation were conducted on an oxidized lead-silver ore containing approximately 12% Pb and 500 g/t Ag. Over 60% of the silver was leached when the ore was ground to passing 0.15mm, whereas 50-60% of the silver was leached

Sequential leaching is a well-established testing procedure, which has been in use since the 1980s. Sequential leaching is a complex procedure. Staff conducting these tests require a high level of mineralogical expertise and strictly controlled laboratory quality control if the test results are to be accurate and reproducible.

(leaching) Basically gold and silver leaching involves spraying a cyanide so- lution on the ore to dissolve the metal values, collecting the solution contain- ing the dissolved metals, and recovering the metal from the solution By elimi- nating milling, leaching reduces.

Ovacik cyanidation plant leaching time, 24 hours for the constant 100 Mg/h ore feed rate was applied as optimal for all lead nitrate tests. Results showed the increase in gold and silver recoveries between 0.4-1.2% for gold and 3.9-11.6% for silver at the end of 24

became feasible with introduction of heap leaching technologies (Marsden, 2009). In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in Figure 2.

Microbial ore leaching (bioleaching) is the process of extracting metals from ores with the use of microorganisms. This method is used to recover many different precious metals like copper, lead, zinc, gold, silver, and nickel. Microorganisms are used because

Microbial leaching is the process by which metals are dissolved from ore bearing rocks using microorganisms. For the last 10 centuries, microorganisms Bioleaching has been discussed with copper, uranium, gold, silver and silica. Copper Leaching Throughout the

Leaching of a high grade gold/silver ore with the celp resulted in higher silver and gold extractions while using a lower cyanide concentration. As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying rational solutions

Phase II Final Report -- Cyanide-Free Biocatalyzed Leaching of Gold and Silver Ore (research sponsored by U.S. National Science Foundation), January 1998, pp.42 plus appendices. Paper presented at the Third International Conference on Minerals Bioprocessing in Mining, Big Sky, MT, 1996 -- A New Alternative to Cyanidation: Biocatalyzed Bisulfide Leaching .

1.4 Chemistry of Gold and Silver Heap Leaching The chemistry of leaching gold and silver from their ores is essentially the same for both metals, and many ores contain a mixture of the two. A dilute alkaline solution of sodium cyanide dissolves these metals without dissolving many other ore components (copper, zinc, mercury, and iron are the most common soluble impurities).
