How does weathering affect limestone?
Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the …

Extraction of iron
The raw materials: iron ore (hematite), coke (an impure form of carbon), and limestone are added into the top of the blast furnace. Hot air is blown into the bottom. Zone 1. Coke burns in the hot air forming carbon dioxide The reaction is exothermic so it gives off heat, heating the furnace. carbon + oxygen → carbon dioxide. Zone 2

Why do we use coke instead of coal in order to reduce FeO as …
Also, coke helps to make the charge of iron oxides and limestone more porous to permit gas flow up and droplets of liquid iron and slag down. The coke oven heating drives off volatiles from the coal, which are a valuable source of chemicals, and contain much of the undesirable $ce{S}$ and $ce{P}$, which would otherwise go into the pig iron.

Dissolving Limestone
Why are you "trying to extract the bones quickly!"? As a rule, quickly dissolving the limestone will require a strong or concentrated acid, which will etch the fossils. All the fine structure, thin bones, and surface detail will be destroyed, and you will end up with a half-dissolved lump remaining from only the largest and thickest bones.
