How Aluminium is Made The Australian Aluminium Council

Bauxite Mining Bauxite in Australia is almost always found near the surface and is generally extracted using open cast (surface) mining The processes involved include land clearing, removal of overburden where required, transport, and crushingOpen pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coalBasics of an open pit mine Mine Jan 09, 2016 Basic Concept 12) Open pit Mining method 13) Bench 14) Open Pit Bench Terminology 15) Bench height 16) Cutoff grade 17) Open Pit Stability: i) Pit slope ii) Pit wall stability iii) Rock strength iv) Pit Depth v) Pit diameter vi) Water Damage vii) Strip Ratio (SR) 18) Openpit mining sequence 19) Various openpit and orebody Surface mining planning and design of open pit miningThere are four main mining methods: underground, open surface (pit), placer, and insitu mining Underground mines are more expensive and are often used to reach deeper deposits Surface mines are typically used for more shallow and less valuable deposits Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environmentsWhat are the main methods of mining?
