Agitated Copper Leaching & Cementation Process

Hydrometallurgy is used for copper recovery for than 300 years Already in 1670 the mine waters were treated with iron to precipitate copper However two hundred years were needed to process oxide ores by vat leaching and copper cementation with iron The development most important to copper hydrometallurgy both with respect to theCementation and precipitation were the main recovery methods until earlier this century and produced impure copper products Electrolysis or electrowinning of 99 15 to 99 85 percent copper from vat leaching of high grade copper ore was proven feasible in the United States in 1914This paper deals with the investigation of column leaching of low grade ores from the copper mine Cerovo Serbia (the approximate Cu content in the ore ranges from 0 2 0 3 with 10 copper in the form of oxide minerals) The leaching experiments were performed using sulphuric acid solutions whereby the kinetics of copperSilica Ore Quality Copper Ore Vat Leach Cementation Ore Agitation Equipment Numerous In Variety In Cyanide Solution Needed Per Tonne Of Ore Cyanidation How Do You Process Tin Ore Sketch Of Lump Ore Process Slurry Pump For Gold Ore Quality Control Aluminum Ore Manufacturer Sell Ore For Gold Mine In North Korea Africa Suppliers Of Nickel

Copper Oxide Ore Leaching Ability And Cementation Behavior

In the leaching operation four factors of acid concentration temperature time and pulp density have been studied at three levels over in order to study copper cementation by iron powder four factors of pH temperature time and amount of iron powder are optimized at three levels Finally it is found that increasing acid concentration temperature and time will cause an increase in the copper recovery of ores with the leachingMethod that contains three main steps 1) Leaching 2) Solvent Extraction (SX) and 3) Electrowinning (EW) [7] [9] [10] There are other methods to recover copper after leaching [5] Cementation and Ion Exchange (IX) are the two main methods [5] [7] Cementation is the basic method of ydrometallurgy that was h applied by alchemists many years ago [6]Jan 05 2015 both ecology and economy Copper is among the most prevalent and valuable metal used by industry Cementation is one of the most effective and economic techniques for recovering toxic and or valuable metals from industrial waste solution and from leach liquors obtained by leaching low grade copper ore The present study was carriedMar 01 2007 Copper ores are generally found in sulfide and oxidized form in nature Copper may be directly transferred to the aqueous phase by leaching oxidized ores but leaching of sulfide copper ores is difficult The composition and purity of the resulting leaching solution depend on the structure of the ore and the type of reactants used for leaching
