Activated magnesium oxide has a variety of important functions and application advantages in the field of metallurgy, especially in the process of hydrometallurgy. The following is a detailed description of its metallurgical functions:
I. As precipitant
Enhance the grade of nickel and cobalt slag: activated magnesium oxide in the wet precipitation of nickel and cobalt in the process, compared with the traditional precipitant such as sodium hydroxide, can significantly enhance the grade of nickel and cobalt slag, thereby improving the quality and value of the final product.
Reduce water content: after using active magnesium oxide as precipitant, the filtration efficiency of nickel and cobalt slag is significantly improved, and the water content after filtration is greatly reduced, which helps to reduce the transportation cost or drying cost, and improve the overall economic efficiency.
Improve filtration efficiency: the high reactivity and suitable particle size distribution of activated magnesium oxide make it able to form precipitation faster when reacting with nickel and cobalt solution, thus improving filtration efficiency.
Simplify the tail water treatment: after using activated magnesium oxide as precipitant, the tail water treatment process becomes simple, efficient and low cost, and easy to recycle, reducing the pollution of the environment.
Reduce costs: due to the advantages of active magnesium oxide in enhancing the grade of nickel and cobalt slag, reducing the water content and improving the filtration efficiency, etc., the overall production cost can be reduced, which is more attractive to downstream customers.
II. The promotion of metal precipitation
High precipitation rate: activated magnesium oxide shows high precipitation rate in the process of hydrometallurgy, which helps to improve the recovery rate of nickel, cobalt and other metals and reduce the waste of resources.
Low magnesium residue: the use of activated magnesium oxide as a precipitant can ensure a high precipitation rate while reducing the residual amount of magnesium in the final product and improving the purity of the product.
III. Application prospects in specific fields
Metal precipitation of copper-cobalt ore and nickel laterite ore: active magnesium oxide shows broad application prospects in the metal precipitation process of copper-cobalt ore and nickel laterite ore. With technological advances and cost reductions, it is expected to be applied on a larger scale in the coming years.
Substitution of traditional precipitant: In specific areas, such as the precipitation process of nickel laterite ore MHP (mixed hydroxide precipitation), activated magnesium oxide has the potential to replace the traditional precipitant, which will promote technological advances and cost reductions in related industries.
Other metallurgical functions
In addition to being a precipitant, activated magnesium oxide can also be used as a sintering aid, stabilizer, etc. in the metallurgical process due to its high activity and high dispersibility, which helps to improve the performance and quality of metallurgical products.
In summary, active magnesium oxide has many important functions and application advantages in the field of metallurgy, and is one of the important materials to promote the technological progress of the metallurgical industry and reduce costs.
