Copper PrecipitationCementation using Scrap Iron

In the search for lower cost methods of recovering copper, the use of sponge iron or particulate iron (as distinguished from iron powder used in powder metallurgy) as precipitants in place of tin cans, detinned scrap iron, or scrap iron is an intriguing possibility. The relatively faster copper precipitation rate obtained with particulate iron as compared to scrap iron promises economic

Cementation (metallurgy) Wikipedia

Apr 17, 2008Cementation is a type of precipitation, a heterogeneous process in which ions are reduced to zero valence at a solid metallic interface. The process is often used to refine leach solutions.. Cementation of copper is a common example. Copper ions in solution, often from an ore leaching process, are precipitated out of solution in the presence of solid iron.

Since copper cementation on less noble metal is diffusion controlled process [19], the aim of the present work is to enhance the rate of cementation of copper on iron by using a rotating iron cylinder. The rate of the copper (II)/iron cementation reaction in the presence of surfactant was determined by measuring the rate of

The ancient brass cementation processes revisited by

Mar 21, 2010Prior to the mastering of metallic zinc production in the mid-19th century, brass making in Europe was based on the so-called cementation process: within a more or less closed vessel, gaseous zinc is produced by the carbothermic reduction of zinc ore at around 1,000°C (±100°C), and simultaneously diffuses into metallic copper. Few ancient brass objects dated
