Economic feasibility and sensitivity analysis of integrating industrial-scale mineral carbonation into mining operations

Hitch and Dipple's model shows the tradeoff of carbonation cost versus carbonation efficiency.

“whose model shows the tradeoff of carbonation cost versus carbonation efficiency (Figure 6).”

Integrated mineral carbonation within the mining industry has the potential to compete with geological storage methods.

“From an economic perspective, integrated mineral carbonation within the mining industry [122] has the potential to compete with geological storage methods [124].”

The economic analysis on the integrated mineral carbonation process in mining industry was first studied by Hitch and Dipple.

The cost of mineral carbonation is reduced via integrating into the mining industry.

The integrating mineral carbonation process yielded a net present value of $131.5 million at a discount rate of 8%, with an operating cost of $82.5/t CO2.

Cubic CaCO3 increases dispersion in paint; acicular or rod-like CaCO3 reinforces rubber and plastics; spherical CaCO3 impacts brightness and transparency of ink.

“For example, dispersion can be increased if cubic CaCO 3 is added as an addition in paint; acicular or rod-like CaCO 3 has a reinforcing effect on rubber and plastics; and spherical CaCO 3 has a significant impact on the brightness and transparency of ink.208”

Different CaCO3 polymorphs were generated by changing carbonation time or after aging.
