Given the active growth of emerging technology industries, it has become essential to have large quantities of critical metals to meet the current demand. In the Chilean mining industry, there is a depletion of high-grade mineral ores, and there is hence a need to increase production levels in the copper industry and diversify its market by extracting other elements.

Carbon dioxide (CO 2) is involved in the processes that affect calcite in karst cavities (White 1988).This gas increases the dissolution capacity of condensation water and, potentially, of the exfiltration water. On the contrary, decrease in the partial pressure of CO 2 (PCO 2) in the cavity can augment degassing of exfiltration water and calcite precipitation.

In the South Pacific between 10°S and 45°S, where the aragonite and calcite saturation horizons are much deeper, the largest gradients are between 800 m to 1800 m. Farther south in the South Pacific, the TA* increase begins at much shallower depths, consistent with the shoaling of the aragonite saturation horizon in these waters.

Marine biogenic calcification is the process by which marine organisms such as oysters and clams form calcium carbonate. Seawater is full of dissolved compounds, ions and nutrients that organisms can use for energy and, in the case of calcification, to build shells and outer structures. Calcifying organisms in the ocean include molluscs, foraminifera, coccolithophores, crustaceans, echinoderms ...
