Iron is chemically active and forms two major series of chemical compounds, the bivalent iron (II), or ferrous, compounds and the trivalent iron (III), or ferric, compounds. Appliions Iron is the most used of all the metals, including 95 % of all the metal tonnage produced worldwide.
Iron (III)Oarsenite caused great problem on environment. Iron (III)O Pentahydrate is also hazardous. When iron containing chemicals enter into the environment they persists and most of the time affects the ecobalance and caused various health problems.
Environmental impact Overall, the entire process of transforming raw bauxite into aluminum is incredibly energy intensive, requiring copious amounts of electricity, water and resources to produce (that is the main reason why power plants are built solely to support the aluminum industry).
Smelting is responsible for 70,000 aciddamaged lakes, 46,000 hectares of stripped vegetation and many more environmental problems. As you see by the pie chart,smelting emits the most sulfur dioxide in Canada by source compared to electric power or transportation.
Environmental Impacts of Mining and Smelting, Environmental Impacts of Mining and Smelting, (extracting the metal from the ore) is associated with the highest exposures and environmental releas
Environmental impacts may also occur through mine establishment, ore extraction, mineral concentration and associated transport, provision of infrastructure (which may include whole townships) and downstream processing.
There are many problems with mining metal ores, such as pollution to the surrounding environment. Mining often means cutting down large areas of land so they make the ores a l ot more accessible. When they have cleared the existing area of land of all the ore then they leave the holes in the ground uncovered which causes many problems.

Oxide copper minerals malachite azurite chrysocolla. Sulfide copper minerals Habitat destruction is one of the main issues associated with mining activity
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".Sources ·
