Albemarle Corp. has completed the previously announced sale of its minerals business, which includes mineral flame retardants and specialty chemicals, to Huber Engineered Materials.

The deal for Albemarle’s Martinswerk mineral flame retardants and specialty chemicals businesses included a manufacturing facility in Bergheim, Germany and Albemarle’s half of Magnifin, a joint-venture with RHI AG at Breitenau, Austria, that produces magnesium hydroxide.

Terms of the transaction were not disclosed. However, the minerals segment generated annual revenue of about $250 million. The segment’s EBITDA margin — earnings before interest, tax, depreciation and amortization divided by total revenue — was about 10 percent. Higher EBITDA margins indicate a more profitable operation.
