What we do
At Horne Smelter, we produce 99.1% pure copper anodes. From their arrival at our Rouyn-Noranda smelter, whether by train or truck, to casting in our anode furnaces, the concentrates and recycled products go through various processing stages before the material can then be processed into cathodes at the CCR Refinery in Montréal-Est.
