锰为炼钢用的重要脱氧剂和合金添加剂,随着钢铁工业的发展,锰铁合金的需要量也日渐增长。我国锰矿资源较为丰富,是钢铁工业的有利因素,但就目前已探明的锰矿资源看,除富矿以外,有些矿区的矿石含锰较低,含铁高或含磷高,或含脉石高,对锰铁合金的生产造成不少困难。 Manganese is an important deoxidizer and alloy additive for steel making. With the development of the steel industry, the demand for ferromanganese alloy is also growing. In our country, manganese ore resources are more abundant, which is a favorable factor for the steel industry. However, in view of the proven manganese resources, some mines have lower manganese content, high iron content or high phosphorus content, , Causing a lot of difficulties in the production of ferromanganese.
