__What is mining?__
Mining is the process of valuable minerals from the earth being extracted, such as gold copper and silver.

__What is metallurgy?__
Metallurgy is the study of chemicals for mining. It involves the separation of minerals from rocks. This takes a number of processes to achieve there complete form.

__Steps For mining Copper.__

 * //Grinding//
 * //Concentrating//
 * //Roasting//
 * //Smelting//
 * //Conversion//
 * //Anode Casting//
 * //Electro Refining//

This type of steps for mining is used for copper there are other steps as well but they are not all the same because different chemicals maybe be used As well as different procedures.

//**Variety of mines**//

__**//Tools used for mining Past/Present?//**__


 * //Present//**
 * Draglines

 * Loaders
 * Haul Trucks
 * High wall Miner
 * Blast hole
 * Dozers
 * Graders


 * //Past//**


 * shovel
 * pick
 * rope
 * saw
 * axe

 * //Types of mines//**




 * //Tunnel mine//**

There created by blasting water and digging in to the soil. Tunnel mines are very dangerous due to cave in and toxic gas. //**Surface mining**//

Surface mining involves soil and rock being removed. It’s the complete opposite of Tunnel mining because the rocks are just left there and the minerals are removed.

__//**Impact on the environment.**//__

Mining involves destruction of habitats and ecosystem. Also it causes problems for people living nearby the mine. Its not just the destruction of land but as well all the carbon dioxide that is used in those gargantuan machines. They require a huge amount of fuel.
