High-purity magnesia is purified by flotation and purification of natural super magnesite ore

The so-called burnt magnesite is called sintered magnesite after calcination at 1550-1600°C. The price of fused magnesia The price of high-purity magnesia is sintered with high-temperature equipment such as shaft kilns, rotary kilns, or two-step calcinations. The burnt magnesia fired from natural magnesite is called sintered magnesia; The physical and chemical indicators are divided into 18 grades, see the national standard GB/T 2273-1998 for details. The molten magnesia formed by smelting magnesite as raw materials in an electric arc furnace to a molten state is called fused magnesia; the magnesia produced by extracting magnesia from seawater is called seawater magnesia. High-purity magnesia is made by flotation and purification of natural super magnesite ore, which is lightly burned, finely ground, pressed ball, and calcined in ultra-high temperature oil shaft kiln. It is a high-quality raw material for making bricks and indeterminate refractories. Light burnt magnesia powder

The mid-grade magnesia is produced from light-burned magnesia with 97% MgO content as raw material, and is produced by pressing ball and high temperature shaft kiln calcination. The product has good sintering degree and dense crystals. It is a high-quality raw material for the production of mid-range magnesia refractory products. It can also be used to manufacture various magnesia bricks, magnesia alumina bricks, ramming materials, and repairing materials.
