: Making Metal Powder

Copper is the primary metal produced by electrolysis but iron, chromium, and magnesium powders are also produced this way. Due to its associated high energy costs, electrolysis is generally limited to high-value powders such as high-conductivity copper powders.

: Copper Precipitation Cementation 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 and ...

1 Chapter 17. Processing of Metal Powders 17.1 Introduction This chapter describes the powder metallurgy (P/M) process, in which metal powders are compacted into desired and often complex shapes and sintered (heated without melting) to form a solid piece. This process first was used by the Egyptians in about 3000 B.C. to iron tools. One of its first
