Get PriceAfter the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and worthless rock, called gangue pronounced gang. The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.

Get PriceFroth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.
Get PriceFlotation of copper is effected in the copper flotation circuit at a slightly acidic pulp pH of about 6.5 to 6.8, the pH being governed by the quantity of sulfur dioxide SO 2 used during conditioning and aeration. A collector selective for copper in an acidic medium is employed, such as ethyl isopropyl thionocarbamate.
Get PriceFlash flotation was developed several decades ago, with the first commercial installation of this technology being at Hammaslahti concentrator in Finland in 1982 Kallioinen and Niitti, 1985. This was a relatively modest sized SK80 cell producing final grade copper concentrate. Since that time, the.

Get Price1 Froth Flotation Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineralwater slurry.
Get PriceA Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1 copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation.
Get PricePine oils, cresylic acid, and longchain alcohols are used for the flotation of copper ores. The flotation concentrates are then dewatered by clarification and filtration, resulting in 10 to 15 percent water, 25 percent sulfur, 25 percent iron, and varying quantities of arsenic, antimony, bismuth, cadmium.
Get PriceTypical applications of flash flotation can be found in gold, silver, platinum and other PGMs, lead, copper, nickel, and combinations thereof. It is worth noting that typically flash flotation is not extensively evaluated during a feasibility study and hence it is unknown if it would be suitable for the project ore and mineralogy.
Get PriceThe copper ions replace zinc atoms on the sphalerite surface creating a pseudocopper mineral surface coverage on the sphalerite which is then collected using copper flotation type collectors. Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit, typically lime is used to raise pH for iron sulphide depression.
Get PriceApproximately two tons of overburden must be removed along with each ton of copper ore. The ratio of overburden to ore is sometimes as high as 5 to 1. The ore itself averages less than 0.7 copper in US mines. Copper ore normally is crushed, ground, and concentrated, usually by flotation, to produce a beneficiated ore containing about 25 copper.
Get PriceCopper in the USA Bright Future Glorious Past US History. The largescale mining of copper had its origins in the late 1800s, primarily in the American West. Small mines existed around the country, particularly in the Upper Peninsula of Michigan and in Arizona, but they were able to extract copper only from highgrade ores.
