Mining and Quarrying ImpactsIntroductionMining and quarrying extract a wide range of useful materials from the ground such as coal, metals, and stone. These substances are used widely in building and manufacturing industry, while precious stones have long been used for adornment and decoration. Mining and quarrying involve investigating potential sites of extraction, then .
Mineral Ore Plant. Barite Baryte, or barite, is a mineral consisting of barium sulfate. The baryte group consists of baryte, celestine, anglesite and anhydrite. Baryte itself is generally white or colorless, and is the main source of barium. Baryte and celestine form a .

The increase in the demand for sand and gravel for construction and other purposes such as flood control has placed immense pressure on the environment where sand and gravel resources occur. This study was carried out to determine the environmental effects of sand and gravel mining in Luku, North central Nigeria, using field observations and laboratory analysis of soil .
· The fine particle emissions were mainly low, few tens of μg/m 3, especially for PM 1. This indies that fine particles originate largely from equipment, for example, combustion engines in the quarrying machine.
· Largescale feldspar production began in the US during the 1860s to fill the needs of the New England pottery industry. Feldspar was used in pottery because it gradually melts over a range of temperatures facilitating the melting of clay. It also improves the strength, toughness and durability of the ceramic body.

Common types of material extracted in quarrying activities include limestone, granite and sand. Big Rock Production Plants In Quarry Quarry Process Quarry process, also known as QP, dense grade aggregate (DGA), crusher run and road stone, is a combination of small, 3/4inchorless crushed stone and stone dust.
process is a major source of emissions such as NOx, SOx, CO2, particulate matters etc. In this paper, the role of cement industry is reviewed in causing impact on environment and health. It describes the cement production process and its emission sources followed by overview of emissions and their environmental and health impacts.
emissions. However, since there is sufficient information on the similarity of trapping centres involved in the blue and red emissions (, Bos et al., 1994; Zink and Visocekas, 1997), it can be assumed that IRSL using feldspar''s red emissions may be useful for dating appliions.
