innovations: how hydrometallurgy and the sx/ew process

copper is traditionally known as the "red" metal after its natural color. however, it is also known as a "green" metal for the green patina that it acquires due to weathering. indeed, patinized copper is the architectural focal point of many modern buildings for its natural look.inquire now

extracting copper. extracting copper.

extraction: an ore has to be changed chemically into the metal. this process is called reduction. how this is done, and how much it costs, depends upon the metal's reactivity see reactivity properties. in general, the more reactive the metal, the harder it is to extract it from its ore.inquire now
