FIELD: compositions of lumpy process limes applicable in chemical industry as process raw material, and in metallurgical industry, as fluxes. SUBSTANCE: process lumpy lime contains, wt.%: magnesium oxide 2.5-3.5; sum of iron and aluminum oxides 1.0-1.5; the balance, calcium oxide. Lime density is 2.6-2.8 g/cu.cm. Offered lime due to balanced composition is suitable for use not only in chemical and metallurgical industries but also in construction and agriculture. EFFECT: higher quality of product.
