2) The development of new collectors should focus on the selectivity of the collector rather than the ability to capture.
3) The selection and study of inhibitors should focus on the selective inhibition of inhibitors.
Inhibition effect of gangue minerals in the flotation fluorite salt such as Al3 + 4) further polyvalent metal gold.
5) Some patterns or laws have been proposed in terms of grain level control. The general principle should be: in order to improve the recovery rate, rough roughing is appropriate; in order to ensure the quality of the concentrate, the selection must be finely ground.
6) The general principle of the return mode of the mine should be: to ensure the total recovery rate of fluorite, but also to minimize the amount of impurities entering the selected operation.
7) Fluorite flotation must be low energy consumption, low drug consumption, and the process should be as simple as possible.
High temperature alloy is divided into three kinds of material: 760 ℃ high-temperature material, 1200℃ high temperature and 1500 ℃ high temperature materials, the tensile strength is 800 mpa. On other words,it refers to the metal material worked well in the condition of 760-1500 ℃ or above. It owns excellent high temperature strength, good resistance to oxidation and thermal corrosion resistance, good fatigue properties, fracture toughness and other comprehensive performance, this kind of material has became an irreplaceable key material in military and civilian gas turbine engine hot end components . According to the relevant theory, 760 ℃ high-temperature materials, according to the matrix elements,can be mainly divided into high temperature iron base alloy, nickel base superalloy and cobalt-based super alloy. According to the preparation process,it can be divided into deformation and high temperature alloy, casting high temperature alloy and powder metallurgy super alloy. According to the solid methods,it can be divided into solid solution strengthening, precipitation strengthening and oxide dispersion strengthened with fiber reinforced type, etc.
