This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US$.
Valuation of Aggregate Operations for Banking Purposes (Sand and Gravel and Crushed Stone) Aggregate consists of sand and gravel and crushed stone. The principal consumers of sand and gravel and crushed stone materials are the highway and building construction industries. The principal construction uses include:
Mining companies are likely to find two types of rock when prospecting in Florida for new deposits: relatively hard limestone and soft limestone. The hard limestone will yield a range of high value products including aggregates and other finished stone materials. The soft limestone will be used for lower value products such as limerock base, shell

Due to a lack of current information, the energy requirements of mining and processing, the SHERPA Mine Cost Estimating Model along with the Mine and Mill Equipment Cost, An Estimators Guide from Western Mine Engineering, Inc., was used to calculate the energy required to mine and process limestone. .
Large cars such as these were typical of limestone mining operations in the mid-20th century. Source: Unknown. This old photo provides a good example of a mine, located far from the lakes, which was opened early because it had high quality limestone and thin overburden, reducing quarrying costs.
inventory found 165 active operations, 88% of which were limestone quarries (Nelson and others, 1990). That same inventory counted 1,367 inactive operations, 70% of which were limestone quarries. Aggregate mining is an extractive use of resources: mining alters the landscape and its natural hydrologic system.
