Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·The gold only deposits hosted in rocks of the Rio das Velhas Supergroup show distinctive mineralization styles associated with highly deformed and hydrothermally altered zones along thrust shear belts being characterized by a consistent linear orientation along a plunge defined by the orebodies Lobato et al 1998 They are hosted in banded iron formation BIF
