Messi Biology said that after the cobalt concentrate is precipitated by magnesium oxide or made into cobalt intermediate products (generally crude cobalt hydroxide) or directly made into cobalt chloride, cobalt sulfate and other cobalt salt products. Therefore, the amount of active magnesium oxide used is the most important, and then the active magnesium oxide quantitative slurry transfer device in cobalt precipitation production highlights its necessity.
The utility model discloses a quantitative magnesium oxide slurry transfer device for cobalt sinking production, including: screw feeder, magnesium oxide slurry transfer tank, magnesium oxide slurry transfer pump and cobalt sinking reaction mixing tank; the top of said magnesium oxide slurry transfer tank is provided with a feed inlet, the lower part of the side wall is provided with a discharge outlet, the top of said magnesium oxide slurry transfer tank is connected to the lower end of the new water pipe, the said new water pipe is provided with an electric valve, the said magnesium oxide slurry transfer tank The inlet of said magnesium oxide slurry tank is connected with the discharge end of screw feeder through pipe; the inlet of said magnesium oxide slurry transfer pump is connected with the discharge of magnesium oxide slurry tank through pipe; the upper end of said cobalt sink reaction stirring tank is provided with inlet, the inlet of said cobalt sink reaction stirring tank is connected with the outlet of magnesium oxide slurry transfer pump through pipe. The utility model can realize the uniform addition of magnesium oxide, control the amount of magnesium oxide added, and facilitate the preparation of magnesium oxide slurry according to the requirements of cobalt production.
Messi Biology nickel and cobalt special active magnesium oxide, using Tibetan water magnesite production, raw materials clean and pollution-free, high content, low heavy metal, fast reaction rate, very suitable for application in nickel and cobalt wet metallurgy refining, after many customers many times test data show that in the best process conditions, cobalt recovery rate of more than 99%, slag in Co products more than 36%, higher than sodium carbonate sink cobalt obtained about 25%! Grade of cobalt carbonate, the unit consumption of magnesium oxide is about 0.8tMg0/tCo, and the utilization rate can reach 91%.
