Applications:
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth. Open-pits are sometimes called ‘quarries’ when they produce building materials and dimension stone. TNR‘s 46/90R57 40.00R57 27.00R49 is one of the most used sizes in open pit mining.
Materials commonly extracted from open-pit mines include:
Bitumen Clay Coal Copper oquina Diamonds Iron Gold Gravel and Bedrock Granite Gritstone Gypsum Limestone Marble Molybdenum Silver Uranium Phosphate
