Limestone - Wikipedia

Limestone formations are also common sources of metal ores, because their porosity and permeability, together with their chemical activity, promotes ore deposition in the limestone. The lead - zinc deposits of Missouri and the Northwest Territories are examples of ore deposits hosted in limestone.

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.

Lead smelting - Wikipedia

Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting.

Limestone - Official Satisfactory Wiki

Limestone is a basic type of ore which is abundant in the world. It is primarily used to produce Concrete, an essential material in factory construction.

Copper extraction - Wikipedia

The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation.

Iron ore - Wikipedia

There have also been iron ore mines in Utah and Alabama; however, the last iron ore mine in Utah shut down in 2014 and the last iron ore mine in Alabama shut down in 1975. Canada . In 2017 Canadian iron ore mines produced 49 million tons of iron ore in concentrate pellets and 13.6 million tons of crude steel.
