Mine <br />operation includes establishments <br />operating mines, quarries, or oil <br />and gas wells on their own account or for others on a contract or fee basis. Mining support activities <br />include establishments that perform exploration (except geophysical surveying) and /or other mining <br />services on a contract or fee basis (except mine site preparation and construction of oil /gas pipelines). <br />Establishments in the Mining sector are grouped and classified according to the natural resource mined <br />or to be mined. Industries include establishments that develop the mine site, extract the natural <br />resources, and /or those that beneficiate (i.e., prepare) the mineral mined. Beneficiation is the process <br />whereby the extracted material is reduced to particles that can be separated into mineral and waste, the <br />former suitable for further processing or direct use. The operations that take place in beneficiation are <br />primarily mechanical, such as grinding, washing, magnetic separation, and centrifugal separation. In <br />contrast, manufacturing operations primarily use chemical and electrochemical processes, such as <br />electrolysis and distillation. However, some treatments, such as heat treatments, take place in both the <br />beneficiation and the manufacturing (i.e., smelting /refining) stages. The range of preparation activities <br />varies by mineral and the purity of any given ore deposit. While some minerals, such as petroleum and <br />natural gas, require little or no preparation, others are washed and screened, while yet others, such as <br />gold and silver, can be transformed into bullion before leaving the mine site. <br />Mining, beneficiating, and manufacturing activities often occur in a single location. Separate receipts will <br />be collected for these activities whenever possible. When receipts cannot be broken out between mining <br />and manufacturing, establishments that mine or quarry nonmetallic minerals, beneficiate the nonmetallic <br />minerals into more finished manufactured products are classified based on the primary activity of the <br />establishment. A mine that manufactures a small amount of finished products will be classified in Sector <br />21, Mining. An establishment that mines whose primary output is a more finished manufactured product <br />will be classified in Sector 31 -33, Manufacturing. <br />Cabarrus Economic Development 3003 Dale Earnhardt Boulevard, Kannapolis, NC 28083 USA <br />704.782.4000 1 CabarrusEDC.com I Face Book.com /CabarrusEDC I Twitter.com /CabarrusEDC <br />1 -1 <br />INTERNATIONALECONOA C <br />/���� / ^ /�J /ADDEEEWLLOPMENT COUNCIL <br />Altaalefl �dd�A# DAi W iyAo¢rtiw� <br />Page 494 <br />
