1.1.5 Ore extraction After a mining company has removed overburden, extraction of the mineral ore begins using specialized heavy equipment and machinery, such as loaders, haulers, and dump trucks, which transport the ore to processing facilities using haul roads. This activity creates a unique set of environmental impacts, such as emissions of
A uranium ore sample containing 1 weight percent uranium has approximately 3,300 pCi/g of 226Ra. Most of the radium in older oil-field scale is 226Ra, because the shorter lived 228Ra decays with a half-life of 5.8 years. Figure 3B illustrates the distribution of dissolved 226Ra concentration in 215 samples of produced water from seven major

Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining
Iron ore can be extracted underground by using tunnelling and shaft equipment, or it can be sourced at ground level through the use of open pit mines (also known as surface mines). Iron ore is then
All equipment that is used to collect and prepare sludge samples must be prepared so that it does not contaminate or react with the material being sampled. Contamination can arise if equipment is improperly cleaned or is made of materials that are released into the sample. (Galvanized or chrome-plated implements must be avoided.)
