Silicon steel grade magnesium oxide series products are key basic coating materials for the domestic production of oriented silicon steel, irreplaceable high temperature annealing isolation agents and surface generators, and are also new materials in the field of national strategic industries and high-tech industries that are supported by the state. In the past few years, […]

Hebei Messi Biology Co., Ltd. stated that magnesium oxide, as an additive for chemical materials, starts with magnesium oxide and ends with magnesium oxide, without chemical structure changes. In theory, it will not cause artificial changes to the ecology, which is in line with the new trend of the world’s industrial development that attaches importance

Hebei Messi Biology Co., Ltd. stated that with the increase in China’s electrical steel production, the demand for silicon steel grade magnesium oxide has continued to increase, and the traditional process of preparing magnesium oxide using dolomite as raw material can no longer meet market demand. China is a country rich in brine resources, so

Hebei Messi Biology Co., Ltd. stated that the activated magnesium oxide cobalt extraction process is a method for efficiently recovering cobalt from low-grade cobalt ore. It adopts a combined process including leaching-iron removal-manganese removal-two-stage cobalt precipitation, supplemented by self-produced cobalt precipitation slag and two-in-one oxidant to obtain qualified cobalt hydroxide, realizing the utilization of low-grade

Hebei Messi Biology Co., Ltd. stated that the efficient cobalt extraction process with activated magnesium oxide involves a method for efficiently recovering cobalt from low-grade cobalt ore, which is suitable for application in the mining and metallurgy industry. Cobalt is an important material for manufacturing high-temperature resistant alloys, hard alloys, catalysts, new energy vehicle batteries

1. Brine-lime method Preliminary purified and refined brine and lime milk made from digested and deslagging lime are precipitated in a sedimentation tank, and flocculants are added to the obtained slurry. After sufficient mixing, the slurry is separated in a sedimentation tank, and then filtered, washed, dried, and crushed to obtain the finished magnesium oxide.
