• Extraction Calcium

    In fact, extracting pure calcium via electrolysis, the developed process is clean and reduces unwanted wastage. However, in terms of mining its ore, there are a few issues, environmentally in particular. In terms of quarrying limestone (an ore of a calcium), the waste product and results of pollution need to be taken into account.
