Introduction Fluorite can be used in three major industries such as metallurgy, chemical industry and building materials, having an important relationship with the developing of the national economy.
Materials and Methods In order to investigate the mechanism of effect of pH on the flotation about fluorite, how the recovery and zeta-potential of fluorite and calcite change with the pH changing from 4 to 11 respectively was investigated.

As to insulation of external wall mainly rely on thermal insulation material to control heat transfer coefficient of the entire wall.
Now commonly used materials are EPS, XPS boards, polyurethane, ETIRS, thermal insulation glazed hollow bead mortar and inorganic thermal insulation mortar mineral wool, etc.
About the choice of materials, should consider the factors, such as local materials, actual weather conditions, construction technology and cost of local conditions.
