Copper sulfate pentahydrate | CuSO4.5H2O - PubChem

COPPER SULFATE PENTAHYDRATE can be dehydrated by heating. Serves as a weak oxidizing agent. Causes hydroxylamine to ignite. Gains water readily. The hydrated salt is vigorously reduced by hydroxylamine [Mellor 8:292(1946-1947)]. Both forms are incompatible with finely powdered metals. These copper oxide ores are usually leached using sulfuric acid to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate solution.

Treatment of Mixed Sulfide Oxide Ores of Copper

Ferric sulfate (or even better, ferric chloride, where salt is easily available) has many possibilities in connection with a mixed copper ore. It will attack and oxidize the sulfides and will dissolve the oxidized minerals and the artificial oxides resulting from the attack on the sulfides. As copper sulphate contains 25% copper metal, the copper content of a 1% Bordeaux mixture would be 0-25 % copper. The quantity of lime used can be reduced considerably. Actually 1 kg copper sulphate requires only 0.225 kg of chemically pure hydrated lime to precipitate all the copper.
