Anhydrous Copper Sulfate as Flotation Activator
YuXing supplies anhydrous copper sulfate for mineral flotation applications where copper sulfate chemistry is required as an activator.
It is commonly evaluated for activation of sphalerite and other sulfide minerals. Buyers may also compare with copper sulfate pentahydrate depending on grade, dosing and logistics requirements.
Selection Notes for Buyers
- Confirm anhydrous grade, CAS, purity and appearance.
- Share whether the application requires activator use in zinc or polymetallic flotation.
- Compare anhydrous and pentahydrate forms based on active content and handling.
- Request available TDS, MSDS and CoA before shipment.
Packaging, Storage & Documents
Typical packaging is 25 kg bags. Store sealed and dry to avoid moisture pickup.
YuXing can provide available specifications, MSDS, CoA and export documents according to supplied batch.
Anhydrous Copper Sulfate: Grade and Hydration Control
Anhydrous copper sulfate and copper sulfate pentahydrate are not purchased on the same mass basis. The water of crystallization changes molecular weight, copper content, appearance and the quantity needed to deliver the same active copper sulfate.
Key Purchasing Parameters
- Specify anhydrous CuSO₄ rather than relying only on the name copper sulfate.
- Confirm CuSO₄ assay, copper content, moisture, iron and water-insoluble matter.
- For flotation activation, provide ore type, mineral target, pulp pH and current dosage.
- Protect the product from moisture and confirm sealed inner packaging for export.

Compare copper sulfate pentahydrate, zinc sulfate, mining chemicals as part of the wider process review; these products should not be treated as direct substitutes without application testing.
Information to Include in an Inquiry
Include the assay basis, required impurity limits, application, monthly consumption, packaging and destination port in the inquiry so the correct copper sulfate form can be quoted.
Frequently Asked Questions
What is anhydrous copper sulfate used for in flotation?
