Impure copper-sulphate solutions other than those obtained from ores such as those obtained in electrolytic operations, may be purified from iron in the same way by distributing the liquid upon the porous mass and exposing it to the air as above described. The Specification in the original form...
A comparison has been made of the extraction of Cu(II) and Fe(III) from chloride and sulphate solutions with LIX 64N in kerosene. The effects on extraction of pH, anion concentration, and temperature were examined, and attention was paid to the ionic strength of the aqueous media, some ...

Calcium sulphate hemihydrate plaster slurry comprising a set-inhibiting agent, for example, a polymer or copolymer of an acid having the formula R 1 HC═CR 2 --COOH wherein R 1 and R 2 are hydrogen or methyl. The invention also includes a method of rapid setting of the inhibited slurry ...
Samples of four metals A, B, C and D were taken and added to the following solution one by one. The results obtained have been tabulated as follows. Metal A. Iron II sulphate Cooper II sulphate Zinc sulphate Silver nitrate B. Displacement 2c No rea
Copperas is iron sulphate mixed with lime, and oxidation produces a golden colour. Usually, the methods are distinguished by appearance. Knowing the original painting method is critical for historical context and conservation, so the research program evaluated characterization methods to supplement visual...
Much is known about genetic susceptibility, uptake and dissemination of PrPSc in the body, but many aspects of prion diseases are still unknown. Different proteomic techniques have been used during the last...
