Cementation - an overview | ScienceDirect Topics

Cementation is beneficial to thick sands for the formation of good reservoirs. The middle part of thick sands is even good for high porosity development. According to the correlation between mid-deep reservoir properties and the content of carbonate cement in the Raoyang Sag, when the shortest distance from sandstone to mudstone is less than 0.5 m, the content of carbonate cements is usually ...

Copper cementation on nickel discs: Canadian

1971-10-3 · The cementation of copper on various types of nickel discs has been studied in dilute cupric sulphate solutions. Activation of the cathode nickel discs with Te +4 was necessary to achieve reproducible rates, whereas satisfactory results were obtained with mint nickel discs using only a chemical polishing treatment Attempts to cement copper on discs of nickel-copper alloys were

Tellurium - an overview | ScienceDirect Topics

Tellurium is recovered from the solution by cementation with copper. Copper telluride is leached with caustic soda and air to form a sodium tellurite solution. This solution, along with excess free caustic soda, is then electrolyzed in a cell using stainless steel anodes to produce tellurium metal (Kirk-Othmer, 1997).
