Copper sulfate

It is the compound of copper, sulfur and oxygen which is very useful chemicals and can be used in different industries.


  • In the Oil refinery
  • Electroplating
  • Antiseptic
  • In the preparation of pigments
  • Tanning industry
  • Agriculture
  • In the textile industry use as mordent
  • In the batteries use as electrolyte
  • Preserver for wood pulp and ground pulp
  • Lithography and engraving process
  • Rayon preparation
  • Rubber manufacturing
  • In the preparation of steel


  • Technical
  • Laboratory grade
  • AR grade

Pure grade can be used in the pharmaceutical and electroplating industries.

Technical grade is used in wood and Leather preservation.

AR grade can be used in analytical process

Manufacturing process

Copper sulfate can be obtained by the reaction of dilute sulfuric acid and copper scrape.

In other words copper wasted put in the sulfuric acid solution which is performed in the Lead lined vessels along with lead coils. By adding the concentrated sulfuric acid, water and mother lacquers 50% minimum concentration is achieved.

It keeps in open steam while the temperature held between 60 to 70 C.

By air blower continuously supply the air to solution for getting oxygen .After the completion of the reaction the solution is to be filtered. For this purpose an open pane evaporate  has been used.

After that process the solution becoming cool and getting the form of crystals.

These crystals are called copper sulfate.

Heathen the  crystals on the wire gage screen kept the minimum temperature  at 60 C
