CONCLUSIONS 1) Mathematical modelling of electrochemical chloride extraction can be undertaken by following classic electrochemical principles. Thus, the movement of chlorides during extraction may be modelled by means of Nernst-Planck equation, specially applied to the boundary conditions of a desorption process.

Step 1: extraction of raw materials. The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting.

Cement production is a carbon-intensive industrial process, with the sector contributing ∼8% of global anthropogenic CO2 emissions. On average, producing each kilogram of cement leads to the emission of 1 kg of CO2─the combination of fuel combustion emissions and carbon released from the feedstock, limestone (CaCO3). Here we report …
