Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore.Jun 19, 2012 David Shukman takes a look inside the world's largest iron ore mine.

Iron ore production Interesting Facts about Iron Ore 9 The history. Australia is the first country where iron ore was deposited in 1880. Whereas small scale mining was begun early 1900s.
Processes copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.
Mining of coal and metallic minerals in Washington began in the mid to late 1800s. Coal production in Washington hit a high in 2003 with an estimated total production of 6,232,000 short tons, yet production ceased in 2006. Metals mining during the same general time period occurred on both sides of the Cascade divide, but was largely concentrated in the northeastern portion of.

Lode Mining. Lode deposits are the targets for gold prospectors seeking gold at the site of its deposit from mineral solutions. Gold is collected in a precipitate form and further purified. in lode mining, ores of gold are collected from the source by quarrying rocks with the ore.
Education. Copper is an amazing element. It transmits electricity and transfers heat efficiently. It delivers drinking water superbly. It’s an effective anti-fouling agent (kills algae, barnacles and worms at sea) and antimicrobial surface (kills infectious bacteria, fungi and viruses in the indoor environment). Yet, it is essential nutritionally for a healthy life.
