21. Surface mining can make use of any of the following three types: (a) Open-pit mining in which machines dig holes and remove the ores (e.g. copper, iron, gravel, limestone, sandstone, ma rble, granite). (b) Dredging in which chained buckets and draglines are used which scrap up the minerals from under-water mineral deposits.

Milling or Mineral Processing 26 Primary Steps in Processing Minerals 1. Sampling - is the removal of a portion which represents a whole needed for the analysis of this material. 2. Analysis - is important to evaluate the valuable component in an ore. This includes chemical, mineral and particle size analysis. 3.
2. The general definition of a mineral encompasses the following criteria: 1. Naturally occurring 2. Stable at room temperature 3. Represented by a chemical formula 4. Usually abiogenic 5. Ordered atomic arrangement The …
15. Type of Extraction of Minerals The process of taking out minerals from rocks buried under the earth's surface is called mining. Minerals that lie at shallow depths are taken out by removing the surface layer; this is known as open-cast mining. Deep bores, called shafts, have to be made to reach mineral deposits that lie at great depths.
8 Columbite-tantalite Columbite-tantalite group is a mineral used widely in technology. Electronics, automotive systems and health products like the pacemaker need this mineral to operate. It is mined in Africa and has earned the name of Coltan over the last few years. 9 Copper Copper is a common metal throughout the world.
