Copper Sulfate General Fact Sheet

Eating large amounts of copper sulfate can lead to nausea, vomiting, and damage to body tissues, blood cells, the liver, and kidneys. With extreme exposures, shock and death can occur. Copper sulfate affects animals in a similar way. Signs of poisoning in animals include lack of appetite, vomiting, dehydration, shock, and death.

Genesis of copper

Shallow marine sandstone-shale-carbonate sedimentary rocks of the Paleoproterozoic northern Cuddapah basin host copper (Nallakonda deposit), copper-lead (Dhukonda deposit), and lead mineralization (Bandalamottu deposit) which together constitute the Agnigundala Sulfide Belt. The Cu sulfide mineralization in sandstone is both stratabound and disseminated, and Pb sulfide

10 Reasons Not to Use Copper Sulfate for Water Treatment

Nov 30, 2021Thus, using copper sulfate will create more work in the end. It does not biodegrade. As stated above, copper sulfate accumulates as a heavy metal precipitate once it is applied to water. Because of this, it does not biodegrade. A buildup of copper sulfate can lead to a sterile water bottom, which can decrease and kill beneficial bacteria.

Lead isotope compositions of Late Cretaceous and early

Lead isotope compositions of the youngest porphyries in the igneous complexes are similar to those in most sulfide minerals within the associated porphyry copper deposit. This Pb isotope similarity argues for a genetic link between them. However, not all Pb in the sulfide minerals in porphyry copper deposits is magmatically derived.

Role of sodium sulfide in the flotation of oxidized copper

Aug 01, 1986This paper reviews uses of sodium sulfide in the flotation of oxide minerals of copper, lead, and zinc. The activation and depression effects of sodium sulfide are of particular importance because of their applications with oxidized lead and copper ores. In spite of its industrial importance, the nature of the heterogeneous reactions between sulfide ions in solution and the surface of oxidized
