Hydrogen peroxide first oxidizes the cyanide to cyanate, and then the cyanate is hydrolyzed to carbonate. The reaction formula is: CN - +H 2 O 2 - CNO - +H 2 O CNO - +2H 2 O - NH 4 + +CO 3 2 - The reaction is very rapid. H 2 O 2 does not produce any harmful toxic products after reaction with cya

First, the activation of the mine (1) activity Some scientists recommend using the following formula to determine the activity of a mine. Where A—the volume of the active flow belt; V———The total volume of the mine bin. If there are no arches or nodules at all, the

Electrodialysis is widely used in the treatment of brackish water, fluorine-containing water, seawater desalination, salt production, boiler feed water purification, etc. due to its high salt removal efficiency. Kunming Institute of Metallurgy cyanide barren solution for both CN - from recovering,

The oil viscosity is an important factor affecting the performance and life of the Cummins generator set. If the oil viscosity is too high, the engine friction resistance of the generator set increases, and at the same time, the pumping performance of the oil is poor, and the local lubrication can

Rapid economic development in China, leading to a huge demand for steel products. Iron ore is used as a raw material for iron making, and the development of its sorting technology is directly related to the utilization level of iron ore raw materials.
