Savona Equipment is your source for New, Used, and Reconditioned Concentrating Tables o of many types, sizes, and manufacturers for recovering fine gold and other precious metals from concentrate. All our refurbished concentrating tables will be completely disassembled and inspected. Any concentrating table parts that are broken or worn will be fully repaired or replaced as required.
If this ore also contains 1g/t Au (for GSR =1), and 90% recovery to concentrate is achieved, then 0.90g will be recovered and with a concentration ratio of 20 (5% to concentrate) this corresponds to 18g/t Au in concentrate. At current gold prices this is worth about US$600.

Concentrating The slurry of water and pulverized ore is mixed with milk of lime to raise the pH and small amounts of special reagents: a frother to make bubbles, and a collector chemical that causes the copper minerals to stick to those bubbles. Air is blown into the tank and the mixture is vigorously agitated like a high-speed blender.
Mining Operations means those activities conducted on the surface of the land for the exploration for, development of, or extraction of a mineral deposit, including, but not limited to, surface mining and the surface effects of underground and in situ mining; on-site transportation, concentrating, milling, evaporation, and other primary processing. .

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...
strip mining – the targeted removal of surface layers to reveal the useful ore/seams underneath. By contrast, sub-surface mining consists of digging tunnels or shafts into the ground to reach deeply buried ore deposits. Some mining, including rare earth elements and uranium extraction, is done using less common methods, such as in-situ leaching.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
