Hydrometallurgy

A reactive metal plates another out of solution

In hydrometallurgy, cementation is the recovery of a dissolved metal from solution by adding a more reactive metal: the added metal dissolves and its electrons reduce the target metal ions, which plate out as a solid, classically copper cemented from solution onto scrap iron. Lung's 1986 The history of copper cementation on iron traces the process to medieval China as arguably the first hydrometallurgical operation. The referent is an electrochemical displacement reaction used to win or purify metals, measured by reaction kinetics and recovery; it has nothing in common with pore-filling rock cement beyond the shared Latin root caementum.[1]

Unit
The amount and rate of metal reduced from solution onto a sacrificial metal
Recovery means
Not applicable
Measured by
Followed by the kinetics of metal deposition, recovery efficiency, and the morphology of the cemented deposit

Sedimentary geology

Precipitated mineral binds grains into rock

In sedimentary geology, cementation is the diagenetic process by which minerals precipitate from pore fluids into the spaces between grains, binding loose sediment into solid rock and reducing its porosity; common cements include quartz, calcite, and clay. Worden and Morad's 2000 review of quartz cementation in oil-field sandstones examines what controls when and how much cement forms. The referent is the precipitation of pore-filling mineral that lithifies sediment, measured by cement volume and its effect on porosity, a different construct from the metallurgist's metal-displacement reaction that carries the same name.[2]

Unit
The volume of precipitated cement filling pore space between grains
Recovery means
Not applicable
Measured by
Quantified by point-counting cement volume, porosity loss, and the paragenetic timing of cement phases
