Copper Cement
Description / Application. Cement copper (precipitated copper) is a product obtained by precipitation (cementation), i.e., by adding iron to the aqueous solution resulting from the leaching of certain ores or waste. It is a finely devised black powder containing oxides and insoluble impurities. Cement copper is often added to the charge which goes to a converting furnace to …

Cementing copper with iron
Consider our friend, the copper chloride leach (aka AP). The chloride ions combine with the copper ions from oxidized copper to create CuCl 2. CuCl 2 will then dissolve copper metal, creating two CuCl. Oxygen will then further oxidize the CuCl, which combines with chloride ions to create more CuCl 2. The cycle can continue almost indefinitely ...
