The direct recovery of precious metals from alkaline cyanide solution is frequently accomplished by the wellestablished MerrillCrowe process involving zincdust cementation. This is particularly true for silver. Plant data from two operations are presented and analyzed in terms of intrinsic reaction features. In such MerrillCrowe plants a plateandframe filter press acts as a ...
We claim: 1. A process for nonferrous metals production from complex sulphide ores containing copper, lead, of zinc, silver and/or gold which comprises: grinding said ore and subjecting it to a flotation operation for obtaining a bulk concentrate of the nonferrous metals minerals and for separating most of the pyrite as a flotation tail, slurrying said concentrate in .
· Co has been known since ancient times, and the first evidence is attributed to blue glazed pottery found in Egyptian tombs dated at 2600 BC. For centuries, Cocontaining materials have been used as pigment. Co as a pure metal was isolated by Georg Brandt in 1735 (Donaldson and Beyersmann 2005 ). Deposits and mining.
· According to Eq. 2, during the cementation reactions with zinc dust, hydrogen is released from acidic, based on Eq. 3, zinc dust can be combined with water and release reactions compete with the reaction of nickel and cadmium, which result in the consumption of zinc dust and limit the available surface for nickel and cadmium .

In 1096 a cementation plant was begun in Chianshan with a yearly production of 190 tonnes. Later, in Europe, the alchemist Paracelsus () described cementation of copper as an example of transmuting Mars (iron) into Venus (copper).

Copper is a fundamental base metal. Approximately 16m tons of the metal are produced every year and 3m tons recycled. Copper is the most efficiently priced conductor, thus is among other things involved in most wiring appliions in many different industries such as: Finally and this is fundamental to the ELSA product, copper is also widely ...
· The Chemical of Africa (CHEMAF) is a hydrometallurgical plant that was commissioned in 2001. It produces copper (Cu) hodes and salts of cobalt (Co) using a process encompassing the sulphuric acid leaching of CuCo oxidised ores under reducing conditions (Na2S2O5 or SO2) followed by the leach liquor purifiion by solvent extraction .

process of cementation arsine also was not detected. In the third experiment the original vaporized electrolyte from the copper sulphate production plant with 300 g/dm3 H 2SO 4, 25 g/dm 3 Cu and 12 g/dm3 As, in the cementation with iron staple, arsine was detected. Copper cementation reaction is represented by the chemical reaction: 2
