Hebei Messi Biology Co., Ltd. stated that the main advantages of the active magnesium oxide process for hydrometallurgy of nickel-cobalt ore are low acid consumption, high nickel-cobalt leaching rate, low neutralizer consumption and high purity of the leachate. The process flow is shown in the figure. The specific process is: limonite-type laterite nickel ore is […]
Hebei Messi Biology Co., Ltd. stated that my country’s magnesium carbonate output has always been at the forefront of the world rankings, especially the low-end magnesium carbonate output has ranked first in the world, and the average annual growth rate of output has remained above 15%. my country has become a major magnesium carbonate producer
China’s magnesium carbonate output is high but its added value is low Read More »
Hebei Messi Biology Co., Ltd. stated that hydromagnesite (4MgCO3·Mg(OH)2·4H2O) is a natural basic carbonate mineral with abundant reserves. It has a pure texture, white color, and low impurity content. It is a high-quality mineral raw material for preparing magnesium products such as flame retardants, activated magnesium oxide, heavy basic magnesium carbonate, and nano magnesium hydroxide.
Hebei Messi Biology Co., Ltd. stated that as an important functional inorganic material, magnesium oxide is widely used in metallurgy, electronics, catalysis, ceramics, coatings, medicine, adsorption, refractory materials and optical materials. Mineral direct pyrolysis, chemical precipitation, gas phase hydration, carbonization, carbon ammonium method, spray pyrolysis, hydrothermal method, sol-gel method and other methods are used to

Hebei Messi Biology Co., Ltd. stated that magnesium hydroxide is a green and environmentally friendly inorganic additive flame retardant. It has the advantages of good thermal stability, non-toxicity, easy availability of raw materials, low price, and no release of toxic and harmful gases during combustion. It can be widely added to polymer materials such as
Hebei Messi Biology Co., Ltd. stated that hydromagnesite is a natural mineral with a chemical composition of 4MgCO·Mg(OH)·4H2O, which is a superior mineral resource in my country. When hydromagnesite is calcined, magnesium carbonate decomposes, releasing carbon dioxide gas and generating magnesium oxide at the same time. The most important factors affecting the activity of magnesium
Hebei Messi Biology Co., Ltd. stated that high-performance magnesium oxide with specific reactivity, particle size and flow characteristics can be used to manufacture transformer silicon steel sheets with grain orientation. During the annealing process, the steel is treated with a magnesium oxide coating to form a glass-ceramic film (forsterite). The insulating properties of this film
Hebei Messi Biology Co., Ltd. stated that magnesium hydroxide is an important inorganic material and is widely used in daily life. Magnesium hydroxide can be used to neutralize acidic wastewater, absorb heavy metals in water, serve as a wastewater decolorizer, and absorb sulfur dioxide in flue gas. As a green inorganic flame retardant, magnesium hydroxide
