processing of ore after extraction is covered in the Mineral Processing guideline as this is common to both open cast and underground mining operations. Open cast mining involves the removal of ore from seams relatively near the surface by means of an open
Welcome back to the surface mining model. In the previous topic we learned about different types of surface mining operations about equipment about different methods that are commonly used to extract coal or different ore deposits. It’s not difficult to understand that mining is one of the most dangerous working environments in the world and in this topic we will go through some of the

Since the identifi ion and characterization of iron and sulfur oxidizing bacteria in the 1940s a rapid progress is being made in minerals engineering based on biological activities. Microorganisms can play a beneficial role in all facets of minerals processing from mining to waste disposal and management. Some of the appli ions such as biologically assisted leaching of copper sulfide
1.2. Open Pit vs. Underground Mining Methods While most mineral deposits can be mined by either surface or underground methods some minerals can only be recovered in a hybrid manner usually by initial extracted by open pit mining followed by
What Are The Advantages And Disadvantages Of Open Cast Mining Advantages and disadvantages on open pit mining? ? Adavantages; Easier access to materials Easier to transport materials to the destination Less hazards in regards to mining in tunnels or underground.
Unit operations. Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classifi ion; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation.

open-cast mining. Deep bores called shafts have to be made to reach mineral deposits that lie at great depths. This is called shaft mining. Petroleum and natural gas occur far below the earth’s surface. Deep wells are bored to take them out this is called drilling
