Remineralization of desalinated water by limestone …
Dissolution of limestone provides two essential ingredients to the water: bicarbonate alkalinity and calcium content. The kinetics of limestone dissolution with CO 2 was studied as a function of inlet CO 2 concentration, water flow velocity, and temperature. The experimental data conformed very well to the Yamauchi model.

Limestone – Its Processing and Application in Iron and
Limestone is also a very important industrial mineral. Its chemical properties make it a valuable mineral for a wide range of industrial/manufacturing uses. Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight.

A bold plan to save the planet turns carbon dioxide into stone
carbon dioxide: (or CO 2) A colorless, odorless gas produced by all animals when the oxygen they inhale reacts with the carbon-rich foods that they've eaten. Carbon dioxide also is released when organic matter burns (including fossil fuels like oil or gas). Carbon dioxide acts as a greenhouse gas, trapping heat in Earth's atmosphere.

Lesson Explainer: Extracting Iron | Nagwa
Limestone is primarily calcium carbonate. When we add limestone to a blast furnace, the calcium carbonate decomposes to form calcium oxide and carbon dioxide. The calcium oxide then reacts with silicon dioxide in the charge mixture. This silicon dioxide is present as sandy impurities, which exist in the hematite ore.

The process described is to inject liquefied carbon dioxide into basalt formations, even if the basalt is very old. This makes the it plausible that we could scrub the excess $mat{CO}_2$ from the atmosphere by: growing plants, burning those plants, capturing the CO2, and; burying that carbon using, partly, the energy from the burned plants.
