In the refining process of copper, cobalt and nickel ore in the Democratic Republic of the Congo, a two-stage leaching process is often used. Hebei Messi Biology Co., Ltd. stated that the purpose of adopting two-stage leaching is to achieve a higher leaching rate of copper, nickel and cobalt in the ore, especially the indispensable

Hebei Messi Biology Co., Ltd. stated that polyethylene materials are widely used in high-voltage transmission lines and industrial production. Polyethylene materials have become cable insulation materials due to their superior insulation properties, environmental friendliness and high cost-effectiveness. However, under the DC electric field, space charges are easily accumulated in the internal traps of polyethylene, resulting

With the advancement of science and technology, the performance of electronic components is constantly improving, and the requirements for thermal conductive raw materials are getting higher and higher. Spherical magnesium oxide is gradually being used in the production of large-scale electronic circuits due to its superior properties that other types of thermal conductive materials cannot

Hebei Messi Biology Co., Ltd. stated that nickel and cobalt are valuable metals with a wide range of uses. The methods for extracting nickel and cobalt from nickel-cobalt ores are generally divided into two categories, one is pyrometallurgy and the other is hydrometallurgy. Hydrometallurgy has the advantages of low energy consumption, less pollution and environmental

Hebei Messi Biology Co., Ltd. stated that magnesium oxide production has a history of several decades in my country, and the production process of the product has been basically mature. China has become the world’s largest magnesium oxide producer, with an annual production volume accounting for more than 75% of the world’s total production. However,

Purpose: Hebei Messi Biology Co., Ltd. studies the bactericidal effect and antibacterial ability of nano-magnesium oxide. Method: Different amounts of magnesium oxide were dispersed on the bacteria-contaminated bacterial tablet carrier and left for different times, and the killing rate was calculated to evaluate the bactericidal ability of magnesium oxide; different amounts of magnesium oxide mixed
