Spedden and his coworkers [28}introduced a cone-shaped cementation apparatus. The cone is filled with shredded iron through which copper-bearing solutions are pumped upwards. During operation of these cones they observed that the application of kinetic principles resulted in the production of a more granular and high purity copper cement as

significantly alleviated by the introduction of the Kennecott cone (7)in the USA . Some of the attractions of cementation remain valid today, namely low capital cost and low power consumption, which have resulted in a number of relatively small scale operations. I. t can be a useful option where there is an on-site smelter.

Copper Cementation on Iron
The conditions present in drum cementation most closely resemble a slurry of cement copper. However, similar conditions may exist to some extent in launders, cones, and columns. The cement copper that is abraded from the iron during a normal cementation test contributes to rate enhancement by forming a slurry.
