Copper Products

The Copper Products Plant produces three commercial chemical products: copper sulphate crystals, copper arsenate and sodium antimonate.

Matte from the Kivcet Smelter is ground and leached using pure oxygen and sulphuric acid. The resulting slurry is filtered and the solution is evapourated to produce copper sulphate crystals, which are dried and packaged for sale.

Arsenic- and antimony-bearing dusts are pressure leached using pure oxygen and caustic. A sodium antimonate is produced by filtration and crystalline copper arsenate is made from the resulting filtrate.

As can be seen below, a shipper loads a bag of copper arsenate.
