Calcining magnesite

Among 619 workers in a magnesite plant with 6-20 years of employment, 13 cases of pneumoconiosis were observed, mainly among workers exposed to calcined magnesite. The workers were exposed to dust from crude or calcined magnesite that also contained 1-3% silicon dioxide. [Pg.429]

Owing to its greater purity, synthetic magnesia is whiter than calcined magnesite. [Pg.60]

Stage 5, Cooling The calcined magnesite leaves the calcination zone and starts cooling. [Pg.86]

A typical temperature profile for calcining magnesite to produce caustic-calcined magnesia in a MHF is shown in Figure 5.2. [Pg.86]

Anhydrous magnesium chloride in the molten state has been produced extensively from MgO obtained either from calcined magnesium hydroxide from seawater or from calcined magnesite, as shown in reaction (14.7) ... [Pg.221]

The chief value of calcined magnesite lies in its resistance to attack by basic slags containing CaO and FcgOg. On the other hand, it is susceptible to attack by acidic oxides such as Si02, combining with them to form low-melting compounds. [Pg.100]

Even after it has been calcined, magnesite is attacked by strong acids this property is made use of in the analysis of magnesite. [Pg.100]
