Difficulties in mine ventilation in the future

1. Thermal damage control in deep well mining As the surface minerals are increasingly mined, the mining depth increases, as the ground temperature increases with the depth of the mine, coupled with the exothermic effects of other heat sources (air compression, oxidation process, mechanical equipm

High purity metal preparation technology (2)

Where V is the ion drift velocity; U is the ion mobility; F is the external force acting on the ion, which consists of the electric field force and the force of the conductive electron scattering on the ion. These forces are related to the effective charge number of the ions. The separation is achi
