This would decrease its usefulness in making blister steel ( cementation ), where the speed and amount of carbon absorption is the overriding consideration.
42.
Carbonate concentrates are a relatively minor product produced from copper cementation plants, typically as the end-stage of a heap-leach operation.
43.
This can then be sent to the lab where the two pieces will be soldered and returned for another try-in or final cementation.
44.
Brass is an alloy of copper and zinc and, when it was first developed, methods for producing metallic zinc were unknown . cementation.
45.
Conversely, quilted fossils tend to decompose " after " the cementation of the overlying sediment; hence their upper surfaces are preserved.
46.
Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by biofilms of microorganisms, especially cyanobacteria.
47.
The production of steel by the cementation process was described in a treatise published in Prague in 1574 and was in use in Nuremberg from 1601.
48.
The cementation process, which was lost from the end of the Roman to the early Medieval period, continued in the same way with brass.
49.
Cementation occurs in fissures or other openings of existing rocks and is a dynamic process more or less in equilibrium with a dissolution or dissolving process.
50.
These crucibles are used in the same way as other cementation vessels but with a hole in the top of the vessel to allow pressure to escape.
