Magnesium sedimentation wastewater treatment In addition to calcium ions, the liquid after magnesium precipitation basically does not contain other metal ions, but the pH value is higher than 11, can not be directly discharged. Part of the magnesium wastewater can be used for lime slurry, and the remaining wastewater can be neutralized and discharged to […]

About 20% of the cobalt is still not recovered in one section of the cobalt precipitation process, and this process uses lime neutralization and precipitation to recover the cobalt in the liquid after one section of cobalt precipitation: Ca(OH)2+CoSO4=Co(OH)2↓+CaSO4 At the same time, under the alkaline environment, part of magnesium sulfate will react with lime

After the initial purification of the post-removal liquid and magnesium oxide slurry under certain conditions, that is, to generate cobalt hydroxide precipitation, the reaction is as follows: Mg(OH)2+CoSO4=Co(OH)2↓+MgSO4 In order to get high grade cobalt hydroxide product and high cobalt recovery, the experiment of active magnesium oxide usage was carried out to find out its

Heat dissipation in electronic devices is becoming increasingly important as the packaging density of these devices continues to increase, resulting in the generation of large amounts of heat in a compact packaging space, and poor heat dissipation can significantly compromise the lifetime and performance stability of electronic products. To improve heat dissipation, electrical insulating materials

Congo (Kinshasa) is the country with the largest reserves of cobalt resources in the world, and its production capacity accounts for more than half of the world\’s total production. Cobalt resources in Congo (DRC) mainly exist in the form of copper-cobalt symbiotic ores, and a few are independent cobalt ores. The hydrometallurgy of copper-cobalt ore

At present, global magnesium oxide is mainly used in medicine, food, plastic, paint, coating, rubber, cable, feed, ceramics and other fields. Hebei Messi Biology Co., Ltd. points out that in 2023, China\’s magnesium oxide consumption structure and demand market mainly have the following points. (1)Plastic field Magnesium oxide is widely used in filling polyvinyl chloride

Magnesium hydroxide [Mg(OH)2] is a flame retardant that we are all familiar with. It is often added to polymer materials to improve the safety factor of polymer materials that have problems such as flammability and large smoke. When encountering a fire, magnesium hydroxide will decompose and release bound water after being heated to absorb a

Since the new century, China\’s magnesium carbonate industry has made great development. The annual production of magnesium carbonate in China accounts for one-third of the total global production. With the rapid increase in the production of downstream products, the demand for magnesium carbonate raw materials in China is also increasing rapidly. At present, the annual

Hebei Messi Biology Co., Ltd. adopts the method of producing high-purity nano-magnesia from Bange Lake hydromagnesite in Naqu, Tibet. This method uses the principle of chemical reaction. First, the hydromagnesite is calcined to obtain magnesium oxide, reacted with sulfuric acid, and filtered. The magnesium sulfate solution is obtained, and the solution is purified by using

Recently there are customers consulting food additive magnesium oxide, the volume of magnesium oxide (also called the bulk density) is not very well understood, today Hebei Messi Biology limited company for you to explain in detail the food additive magnesium oxide is light or heavy. First of all, let\’s understand the difference between light magnesium
