    Creating the zero-carbon mine | McKinsey

    Jun 29, 2021 To understand this variation, we have created a comprehensive mine-decarbonization model. This breaks down mining emissions at an equipment level and assesses more than 20 decarbonization options (Exhibit 2). We have used an iron ore mine in Australia as an example to see what the world’s first zero-carbon mine could look like

    The carbon is then removed by screening, across a carbon screen, allowing the liquid and finely ground ore (-100 mesh) to pass through easily, and retaining the carbon on the screen. The carbon is then generally subjected to a heated solution (200 deg to 250 deg F) of (1%) sodium hydroxide and (0.1%) cyanide and the gold is re-dissolved and

    He believes water and gangue removal is something Australian iron ore producers can do onshore to lower the carbon intensity associated with out iron ore exports. Also, a higher quality ore would impart a further economic benefit to iron ore producers through their products commanding higher prices as well as spurring jobs growth in this part

    Feb 18, 2021 In heap leaching highly oxidized ores, the decomposition of cyanide by carbon dioxide may be as great as that caused by the acid constituents of the ore. The decomposition of cyanide by carbon dioxide, as well as by ground acids, is minimized by using sufficient alkali such as lime (CaO) or caustic soda (NaOH) in the leach solution to maintain

    Iron ore mining methods vary by the type of ore being mined. ... a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond, at high temperatures. Thus, the iron ore must be powdered and mixed with coke
