copper L/SX/EW operation, the Bluebird plan of Ranchers Exploration and Development Corporation, came on line1. Copper recovery by L/SX/EX in 1968 In 1968 there were only two widely practiced copper leaching processes using dilute sulphuric acid. The first process, vat leaching of highgrade copper oxide ore followed by EW of

rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated [48]. Pyrometallurgical copper production
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important byproduct of this process is used for the extraction of oxide ores.
CPS Electroless Copper Plating Bench consists of a 6 station wet cleaning and electroless plating process, with 3 pretreatment stations and 3 electroless plating stations respectively. This process is commonly used in semiconductor manufacturing or other high technology products. Stock No TZ270 Category Associated Process Plant Equipment Model
In recent years, apart from a few older plants, direct copper EW has been replaced by copper SXEW in order to make LME Grade 'A' specifiion. The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt
COPPER PLANTS Coarse Copper oxide mineralisation can be preconcentrated by Dense Media Separation (DMS). Preconcentration for low grade copper ore in order to maximise concentrator throughputs and revenues. Our modular of DMS, optical sorting, and spiral concentrator modules are ideally suited and cost effective.
