Lime and dolomite are commonly used in converters and electric arc furnaces, where they help to form slag which draws off harmful impurities such as silicon and phosphorus. Lime is also used to improve productivity in the ore agglomeration process.

More recently, new products and services have been introduced in various steps of the steelmaking process. These have led to major quality improvements in processes such as hot metal desulphurisation and in effluent handling, to name but two.

Steelmaking industry also requires large quantities of water for all its processes. Lime and lime-based products are a cost-effective way of adjusting the mineral content.
